+/**
+ `AFHTTPRequestOperationManager` encapsulates the common patterns of communicating with a web application over HTTP, including request creation, response serialization, network reachability monitoring, and security, as well as request operation management.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
+
+ ## Methods to Override
+
+ To change the behavior of all request operation construction for an `AFHTTPRequestOperationManager` subclass, override `HTTPRequestOperationWithRequest:success:failure`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSSecureCoding & NSCopying Caveats
+

+/**
+ `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
+
+ ## Methods to Override
+
+ To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:completionHandler:`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+/**
+ `AFURLConnectionOperation` is a subclass of `NSOperation` that implements `NSURLConnection` delegate methods.
+
+ ## Subclassing Notes
+
+ This is the base class of all network request operations. You may wish to create your own subclass in order to implement additional `NSURLConnection` delegate methods (see "`NSURLConnection` Delegate Methods" below), or to provide additional properties and/or class constructors.
+
+ If you are creating a subclass that communicates over the HTTP or HTTPS protocols, you may want to consider subclassing `AFHTTPRequestOperation` instead, as it supports specifying acceptable content types or status codes.
+
+ ## NSURLConnection Delegate Methods
+
+ `AFURLConnectionOperation` implements the following `NSURLConnection` delegate methods:
+
+ - `connection:didReceiveResponse:`
+ - `connection:didReceiveData:`
+ - `connectionDidFinishLoading:`
+ - `connection:didFailWithError:`
+ - `connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `connection:willCacheResponse:`
+ - `connectionShouldUseCredentialStorage:`
+ - `connection:needNewBodyStream:`
+ - `connection:willSendRequestForAuthenticationChallenge:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Callbacks and Completion Blocks
+
+ The built-in `completionBlock` provided by `NSOperation` allows for custom behavior to be executed after the request finishes. It is a common pattern for class constructors in subclasses to take callback block parameters, and execute them conditionally in the body of its `completionBlock`. Make sure to handle cancelled operations appropriately when setting a `completionBlock` (i.e. returning early before parsing response data). See the implementation of any of the `AFHTTPRequestOperation` subclasses for an example of this.
+
+ Subclasses are strongly discouraged from overriding `setCompletionBlock:`, as `AFURLConnectionOperation`'s implementation includes a workaround to mitigate retain cycles, and what Apple rather ominously refers to as ["The Deallocation Problem"](http://developer.apple.com/library/ios/#technotes/tn2109/).
+
+ ## SSL Pinning
+
+ Relying on the CA trust model to validate SSL certificates exposes your app to security vulnerabilities, such as man-in-the-middle attacks. For applications that connect to known servers, SSL certificate pinning provides an increased level of security, by checking server certificate validity against those specified in the app bundle.
+
+ SSL with certificate pinning is strongly recommended for any application that transmits sensitive information to an external webservice.
+
+ Connections will be validated on all matching certificates with a `.cer` extension in the bundle root.
+
+ ## NSCoding & NSCopying Conformance
+
+ `AFURLConnectionOperation` conforms to the `NSCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. However, because of the intrinsic limitations of capturing the exact state of an operation at a particular moment, there are some important caveats to keep in mind:
+
+ ### NSCoding Caveats
+
+ - Encoded operations do not include any block or stream properties. Be sure to set `completionBlock`, `outputStream`, and any callback blocks as necessary when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+ - Operations are paused on `encodeWithCoder:`. If the operation was encoded while paused or still executing, its archived state will return `YES` for `isReady`. Otherwise, the state of an operation when encoding will remain unchanged.
+
+ ### NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new operation with the `NSURLRequest` of the original. So rather than an exact copy of the operation at that particular instant, the copying mechanism returns a completely new instance, which can be useful for retrying operations.
+ - A copy of an operation will not include the `outputStream` of the original.
+ - Operation copies do not include `completionBlock`, as it often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ operation when copied.

+/**
+ `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+ ## Subclassing Notes
+
+ This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
+
+ ## NSURLSession & NSURLSessionTask Delegate Methods
+
+ `AFURLSessionManager` implements the following delegate methods:
+
+ ### `NSURLSessionDelegate`
+
+ - `URLSession:didBecomeInvalidWithError:`
+ - `URLSession:didReceiveChallenge:completionHandler:`
+ - `URLSessionDidFinishEventsForBackgroundURLSession:`
+
+ ### `NSURLSessionTaskDelegate`
+
+ - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
+ - `URLSession:task:didReceiveChallenge:completionHandler:`
+ - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
+ - `URLSession:task:didCompleteWithError:`
+
+ ### `NSURLSessionDataDelegate`
+
+ - `URLSession:dataTask:didReceiveResponse:completionHandler:`
+ - `URLSession:dataTask:didBecomeDownloadTask:`
+ - `URLSession:dataTask:didReceiveData:`
+ - `URLSession:dataTask:willCacheResponse:completionHandler:`
+
+ ### `NSURLSessionDownloadDelegate`
+
+ - `URLSession:downloadTask:didFinishDownloadingToURL:`
+ - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSCoding Caveats
+
+ - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+
+ ## NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
+ - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+[![Build Status](https://travis-ci.org/AFNetworking/AFNetworking.svg)](https://travis-ci.org/AFNetworking/AFNetworking)
+
+AFNetworking is a delightful networking library for iOS and Mac OS X. It's built on top of the [Foundation URL Loading System](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/URLLoadingSystem.html), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.
+
+Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.
+
+Choose AFNetworking for your next project, or migrate over your existing projects—you'll be happy you did!

+## Usage
+
+### HTTP Request Operation Manager
+
+`AFHTTPRequestOperationManager` encapsulates the common patterns of communicating with a web application over HTTP, including request creation, response serialization, network reachability monitoring, and security, as well as request operation management.
+
+#### `GET` Request
+
+```objective-c
+AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
+[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
+    NSLog(@"JSON: %@", responseObject);
+} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
+    NSLog(@"Error: %@", error);
+}];
+```
+
+#### `POST` URL-Form-Encoded Request
+
+```objective-c
+AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
+NSDictionary *parameters = @{@"foo": @"bar"};
+[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
+    NSLog(@"JSON: %@", responseObject);
+} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
+    NSLog(@"Error: %@", error);
+}];
+```
+
+#### `POST` Multi-Part Request
+
+```objective-c
+AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
+NSDictionary *parameters = @{@"foo": @"bar"};
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+    [formData appendPartWithFileURL:filePath name:@"image" error:nil];
+} success:^(AFHTTPRequestOperation *operation, id responseObject) {
+    NSLog(@"Success: %@", responseObject);
+} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
+    NSLog(@"Error: %@", error);
+}];
+```
+
+---
+
+### AFURLSessionManager
+
+`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+#### Creating a Download Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
+    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
+    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
+} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
+    NSLog(@"File downloaded to: %@", filePath);
+}];
+[downloadTask resume];
+```
+
+#### Creating an Upload Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"Success: %@ %@", response, responseObject);
+    }
+}];
+[uploadTask resume];
+```
+
+#### Creating an Upload Task for a Multi-Part Request, with Progress
+
+```objective-c
+NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
+    } error:nil];
+
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
+NSProgress *progress = nil;
+
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+
+[uploadTask resume];
+```
+
+#### Creating a Data Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+[dataTask resume];
+```
+
+---
+
+### Request Serialization
+
+Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.
+
+```objective-c
+NSString *URLString = @"http://example.com";
+NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
+```
+
+#### Query String Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
+```
+
+    GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### URL Form Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];
+```
+
+    POST http://example.com/
+    Content-Type: application/x-www-form-urlencoded
+
+    foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### JSON Parameter Encoding
+
+```objective-c
+[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];
+```
+
+    POST http://example.com/
+    Content-Type: application/json
+
+    {"foo": "bar", "baz": [1,2,3]}
+
+---
+
+### Network Reachability Manager
+
+`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
+
+* Do not use Reachability to determine if the original request should be sent.
+	* You should try to send it.
+* You can use Reachability to determine when a request should be automatically retried.
+	* Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
+* Network reachability is a useful tool for determining why a request might have failed.
+	* After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."
+
+See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/).
+
+#### Shared Network Reachability
+
+```objective-c
+[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
+}];
+
+[[AFNetworkReachabilityManager sharedManager] startMonitoring];
+```
+
+#### HTTP Manager Reachability
+
+```objective-c
+NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];
+AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];
+
+NSOperationQueue *operationQueue = manager.operationQueue;
+[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    switch (status) {

+
+### Security Policy
+
+`AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections.
+
+Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.
+
+#### Allowing Invalid SSL Certificates
+
+```objective-c
+AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
+manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
+```
+
+---
+
+### AFHTTPRequestOperation
+
+`AFHTTPRequestOperation` is a subclass of `AFURLConnectionOperation` for requests using the HTTP or HTTPS protocols. It encapsulates the concept of acceptable status codes and content types, which determine the success or failure of a request.
+
+Although `AFHTTPRequestOperationManager` is usually the best way to go about making requests, `AFHTTPRequestOperation` can be used by itself.
+
+#### `GET` with `AFHTTPRequestOperation`
+
+```objective-c
+NSURL *URL = [NSURL URLWithString:@"http://example.com/resources/123.json"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
+op.responseSerializer = [AFJSONResponseSerializer serializer];
+[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
+    NSLog(@"JSON: %@", responseObject);
+} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
+    NSLog(@"Error: %@", error);
+}];
+[[NSOperationQueue mainQueue] addOperation:op];
+```
+
+#### Batch of Operations
+
+```objective-c
+NSMutableArray *mutableOperations = [NSMutableArray array];
+for (NSURL *fileURL in filesToUpload) {
+    NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:fileURL name:@"images[]" error:nil];
+    }];
+
+    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
+
+    [mutableOperations addObject:operation];
+}
+
+NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:@[...] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
+    NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);
+} completionBlock:^(NSArray *operations) {
+    NSLog(@"All operations in batch complete");
+}];
+[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];
+```
+
+## Unit Tests
+
+AFNetworking includes a suite of unit tests within the Tests subdirectory. In order to run the unit tests, you must install the testing dependencies via [CocoaPods](https://cocoapods.org/):
+
+    $ cd Tests
+    $ pod install
+
+Once testing dependencies are installed, you can execute the test suite via the 'iOS Tests' and 'OS X Tests' schemes within Xcode.
+
+### Running Tests from the Command Line
+
+Tests can also be run from the command line or within a continuous integration environment. The [`xcpretty`](https://github.com/supermarin/xcpretty) utility needs to be installed before running the tests from the command line:
+
+    $ gem install xcpretty
+
+Once `xcpretty` is installed, you can execute the suite via `rake test`.

+/**
+ `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a network request operation has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
+
+ You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
+
+    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
+
+ By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
+
+ See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:
+ http://developer.apple.com/library/iOS/#documentation/UserExperience/Conceptual/MobileHIG/UIElementGuidelines/UIElementGuidelines.html#//apple_ref/doc/uid/TP40006556-CH13-SW44

+
+## Example Usage
+
+To perform an HTTP request use the convenient methods found in the Http object. Here is an example usage:
+
+```swift
+let http = Http(baseURL: "http://server.com")
+
+http.request(.GET, path: "/get", completionHandler: {(response, error) in
+     // handle response
+})
+
+http.request(.POST, path: "/post",  parameters: ["key": "value"], 
+                    completionHandler: {(response, error) in
+     // handle response
+})
+...
+```
+
+### Authentication
+
+The library also leverages the build-in foundation support for http/digest authentication and exposes a convenient interface by allowing the credential object to be passed on the request. Here is an example:
+
+> **NOTE:**  It is advised that HTTPS should be used when performing authentication of this type
+
+```swift
+let credential = NSURLCredential(user: "john", 
+                                 password: "pass", 
+                                 persistence: .None)
+
+http.request(.GET, path: "/protected/endpoint", credential: credential, 
+                                completionHandler: {(response, error) in
+   // handle response
+})
+```
+
+You can also set a credential per protection space, so it's automatically picked up once http challenge is requested by the server, thus omitting the need to pass the credential on each request. In this case, you must initialize the ```Http``` object with a custom session configuration object, that has its credentials storage initialized with your credentials:
+
+```swift
+// create a protection space
+var protectionSpace = NSURLProtectionSpace(host: "httpbin.org", 
+                                    port: 443,
+                                    protocol: NSURLProtectionSpaceHTTPS, 
+                                    realm: "me@kennethreitz.com", 
+                                    authenticationMethod: NSURLAuthenticationMethodHTTPDigest)
+
+// setup credential
+// notice that we use '.ForSession' type otherwise credential storage will discard and
+// won't save it when doing 'credentialStorage.setDefaultCredential' later on
+let credential = NSURLCredential(user: user, 
+                                 password: password, 
+                                 persistence: .ForSession)
+
+// assign it to credential storage
+var credentialStorage = NSURLCredentialStorage.sharedCredentialStorage()
+credentialStorage.setDefaultCredential(credential, forProtectionSpace: protectionSpace);
+
+// set up default configuration and assign credential storage
+var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
+configuration.URLCredentialStorage = credentialStorage
+
+// assign custom configuration to Http
+var http = Http(baseURL: "http://httpbin.org", sessionConfig: configuration)
+
+http.request(.GET, path: "/protected/endpoint", completionHandler: {(response, error) in
+   // handle response
+})
+```
+
+### OAuth2 Protocol Support
+
+To support the OAuth2 protocol, we have created a separate library [aerogear-ios-oauth2](https://github.com/aerogear/aerogear-ios-oauth2) that can be easily integrated, in order to provide  out-of-the-box support for communicated with OAuth2 protected endpoints. Please have a look at the "Http and OAuth2Module" section on our [documentation page](http://aerogear.org/docs/guides/aerogear-ios-2.X/Authorization/) for more information. 
+
+Do you want to try it on your end? Follow next section steps.
+
+### Build, test and play with aerogear-ios-http
+
+1. Clone this project
+
+2. Get the dependencies
+
+The project uses [OHHTTPStubs](https://github.com/AliSoftware/OHHTTPStubs) framework for stubbing its http network requests and utilizes [cocoapods](http://cocoapods.org) 0.36 release for handling its dependencies. As a pre-requisite, install [cocoapods](http://blog.cocoapods.org/CocoaPods-0.36/) and then install the pod. On the root directory of the project run:
+```bash
+pod install
+```
+3. open AeroGearHttp.xcworkspace
+
+## Adding the library to your project 
+To add the library in your project, you can either use [CocoaPods](http://cocoapods.org) or manual install in your project. See the respective sections below for instructions:
+
+### Using [CocoaPods](http://cocoapods.org)
+Support for Swift frameworks is supported from [CocoaPods-0.36 release](http://blog.cocoapods.org/CocoaPods-0.36/) upwards. In your ```Podfile``` add:
+
+```
+pod 'AeroGearHttp'
+```
+
+and then:
+
+```bash
+pod install
+```
+
+to install your dependencies
+
+### Manual Installation
+Follow these steps to add the library in your Swift project:
+
+1. Add AeroGearHttp as a [submodule](http://git-scm.com/docs/git-submodule) in your project. Open a terminal and navigate to your project directory. Then enter:
+```bash
+git submodule add https://github.com/aerogear/aerogear-ios-http.git
+```
+2. Open the `aerogear-ios-http` folder, and drag the `AeroGearHttp.xcodeproj` into the file navigator in Xcode.
+3. In Xcode select your application target  and under the "Targets" heading section, ensure that the 'iOS  Deployment Target'  matches the application target of AeroGearHttp.framework (Currently set to 8.0).
+5. Select the  "Build Phases"  heading section,  expand the "Target Dependencies" group and add  `AeroGearHttp.framework`.
+7. Click on the `+` button at the top left of the panel and select "New Copy Files Phase". Rename this new phase to "Copy Frameworks", set the "Destination" to "Frameworks", and add `AeroGearHttp.framework`.
+

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+## Example Usage
+
+#### OAuth2 grant for GET with a predefined config like Facebook
+```swift
+var Http = Http() 						// [1]
+let facebookConfig = FacebookConfig(	// [2]
+    clientId: "YYY",
+    clientSecret: "XXX",
+    scopes:["photo_upload, publish_actions"])
+var oauth2Module = AccountManager.addFacebookAccount(facebookConfig)  // [3]
+http.authzModule = oauth2Module			// [4]
+http.request(.GET, path: "/get", completionHandler: {(response, error) in	// [5]
+	// handle response
+})
+```
+Create an instance of Http [1] from [aerogear-ios-http](https://github.com/aerogear/aerogear-ios-http) a thin layer on top of NSURLSession.
+
+Fill-in the OAuth2 configuration in [2], here we use a predefined Config with all Facebook endpoint filled-in for us.
+
+Create an OAuth2Module from AccountManager's factory method in [3].
+
+Inject OAuth2Module into http object in [4] and uses the http object to GET/POST etc...
+
+See full description in [aerogear.org](https://aerogear.org/docs/guides/aerogear-ios-2.X/Authorization/)
+
+#### OpenID Connect with Keycloak
+```swift
+var Http = Http()
+let keycloakConfig = KeycloakConfig(
+    clientId: "sharedshoot-third-party",
+    host: "http://localhost:8080",
+    realm: "shoot-realm",
+    isOpenIDConnect: true)
+var oauth2Module = AccountManager.addKeycloakAccount(keycloakConfig)
+http.authzModule = oauth2Module
+oauth2Module.login {(accessToken: AnyObject?, claims: OpenIDClaim?, error: NSError?) in // [1]
+    // Do your own stuff here
+}
+
+```
+Similar approach for configuration, here we want to login as Keycloak user, using ```login``` method we get some user information back in OpenIDClaim object.
+
+> **NOTE:**  The latest version of the library works with Keycloak 1.1.0.Final. Previous version of Keycloak 1.0.x will work except for the transparent refresh of tokens (ie: after access token expires you will have to go through grant process).
+
+### Build, test and play with aerogear-ios-oauth2
+
+1. Clone this project
+
+2. Get the dependencies
+
+The project uses [CocoaPods](http://cocoapods.org) for handling its dependencies. As a pre-requisite, install CocoaPods and then install the pod. On the root directory of the project run:
+```bash
+pod install
+```
+3. open AeroGearOAuth2.xcworkspace
+
+## Adding the library to your project 
+To add the library in your project, you can either use [CocoaPods](http://cocoapods.org) or manual install in your project. See the respective sections below for instructions:
+
+### Using [CocoaPods](http://cocoapods.org)
+In your ```Podfile``` add:
+
+```
+pod 'AeroGearOAuth2'
+```
+
+and then:
+
+```bash
+pod install
+```
+
+to install your dependencies
+
+### Manual Installation
+Follow these steps to add the library in your Swift project:
+
+1. Add AeroGearOAuth2 as a [submodule](http://git-scm.com/docs/git-submodule) in your project. Open a terminal and navigate to your project directory. Then enter:
+```bash
+git submodule add https://github.com/aerogear/aerogear-ios-oauth2.git
+```
+2. Open the `aerogear-ios-oauth2` folder, and drag the `AeroGearOAuth2.xcodeproj` into the file navigator in Xcode.
+3. In Xcode select your application target  and under the "Targets" heading section, ensure that the 'iOS  Deployment Target'  matches the application target of AeroGearOAuth2.framework (Currently set to 8.0).
+5. Select the  "Build Phases"  heading section,  expand the "Target Dependencies" group and add  `AeroGearOAuth2.framework`.
+7. Click on the `+` button at the top left of the panel and select "New Copy Files Phase". Rename this new phase to "Copy Frameworks", set the "Destination" to "Frameworks", and add `AeroGearOAuth2.framework`.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,

+[![Build Status](https://travis-ci.org/graetzer/GDataXML-HTML.svg?branch=master)](https://travis-ci.org/graetzer/GDataXML-HTML)
+
+GDataXML-HTML is a HTML/XML parser for iOS and OSX, based on Google's GDataXML. As the name suggest it adds support for the HTMLparser module of libxml2 and enables you to deal with non validating XML or HTML.
+
+So you can use e.g. XPath to parse Websites with reasonable performance
+
+# Use in your own project #
+
+### Install with CocoaPods
+
+pod 'GDataXML-HTML', '~> 1.3.0'
+
+### Manually ###
+
+1. First add the files from the Pod/Classes folder in this project to your source tree, then include them somewhere in your code,
+
+2. In Xcode choose the project file (in the project navigator, the top item).
+
+3. In the list choose your project target and select 'Build Settings' at the top of the window.
+Then you should see a list of build options.
+
+4. Add this line to 'Header Search Paths' (use search bar to find the right option)
+/usr/include/libxml2
+
+5. Add this line to 'Other Linker Flags':
+-lxml2
+
+# Examples #
+There are usage examples inside the GDataXML_HTMLViewController.m file.
+
+### Other examples for GDataXML on the web: ###
