**SOAPEngine**
================

This generic [SOAP](http://www.wikipedia.org/wiki/SOAP) client allows you to access web services using a your [iOS](http://www.wikipedia.org/wiki/IOS) app, [Mac OS X](http://www.wikipedia.org/wiki/OS_X) app and [Apple TV](http://www.apple.com/tv/) app.

With this Framework you can create [iPhone](http://www.wikipedia.org/wiki/IPhone), [iPad](http://www.wikipedia.org/wiki/IPad), [Mac OS X](http://www.wikipedia.org/wiki/OS_X) and [AppleTv](http://www.apple.com/tv/) apps that supports [SOAP](http://www.wikipedia.org/wiki/SOAP) Client Protocol. This framework able executes methods at remote web services with [SOAP](http://www.wikipedia.org/wiki/SOAP) standard protocol.

## Features
---
* Support both 2001 (v1.1) and 2003 (v1.2) [XML](http://www.wikipedia.org/wiki/XML) schema.
* Support array, array of structs, dictionary and sets.
* Support for user-defined object with serialization of complex data types and array of complex data types, even embedded multilevel structures.
* Supports [ASMX](http://www.wikipedia.org/wiki/ASP.NET#Other_files) Services, [WCF](http://www.wikipedia.org/wiki/Windows_Communication_Foundation) Services ([SVC](http://www.wikipedia.org/wiki/ASP.NET#Other_files)) and now also the [WSDL](http://www.wikipedia.org/wiki/Web_Services_Description_Language) definitions.
* Supports [Basic](http://www.wikipedia.org/wiki/Basic_access_authentication), [Digest](http://www.wikipedia.org/wiki/Digest_access_authentication) and [NTLM](http://www.wikipedia.org/wiki/Integrated_Windows_Authentication) Authentication, [WS-Security](http://www.wikipedia.org/wiki/WS-Security), Client side Certificate and custom security header.
* Supports [iOS](http://www.wikipedia.org/wiki/IOS) Social Account to send [OAuth2.0](http://www.wikipedia.org/wiki/OAuth) token on the request.
* [AES256](http://www.wikipedia.org/wiki/Advanced_Encryption_Standard) or [3DES](http://www.wikipedia.org/wiki/Triple_DES) Encrypt/Decrypt data without [SSL](http://www.wikipedia.org/w/index.php?title=Transport_Layer_Security) security.
* An example of service and how to use it is included in source code.

## Requirements for [iOS](http://www.wikipedia.org/wiki/IOS)
---
* [iOS](http://www.wikipedia.org/wiki/IOS) 7.1, and later
* [Xcode](http://www.wikipedia.org/wiki/Xcode) 7.1 or later
* Security.framework
* Accounts.framework
* Foundation.framework
* UIKit.framework
* libxml2.dylib

## Requirements for [Mac OS X](http://www.wikipedia.org/wiki/OS_X)
---
* [OS X](http://www.wikipedia.org/wiki/OS_X) 10.9 and later
* [Xcode](http://www.wikipedia.org/wiki/Xcode) 7.1 or later
* Security.framework
* Accounts.framework
* Foundation.framework
* AppKit.framework
* Cocoa.framework
* libxml2.dylib

## Requirements for [Apple TV](http://www.apple.com/tv/)
---
* [iOS](http://www.wikipedia.org/wiki/IOS) 9.0, and later
* [Xcode](http://www.wikipedia.org/wiki/Xcode) 7.1 or later
* Security.framework
* Foundation.framework
* UIKit.framework
* libxml2.dylib

## Limitations
---
* for [WCF](http://www.wikipedia.org/wiki/Windows_Communication_Foundation) services, only supports basic http bindings ([basicHttpBinding](https://msdn.microsoft.com/library/ms731361.aspx)).
* in [Mac OS X](http://www.wikipedia.org/wiki/OS_X) unsupported image objects, instead you can use the [NSData](https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSData_Class/index.html).

## Security for Xcode 7.x
---
The new Xcode 7 requires an additional setting for the apps, if this setting does not exist you will see a log message like this:

`App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.`

To resolve this, add few keys in info.plist, the steps are:

1. Open `info.plist` file of your project.
2. Add a Key called `NSAppTransportSecurity` as a Dictionary.
3. Add a Subkey called `NSAllowsArbitraryLoads` as Boolean and set its value to YES as like following image.

## How to use
---
with [**Delegates**](https://developer.apple.com/library/ios/documentation/General/Conceptual/CocoaEncyclopedia/DelegatesandDataSources/DelegatesandDataSources.html) :

``` objective-c
	#import <SOAPEngine64/SOAPEngine.h>

	// standard soap service (.asmx)
	SOAPEngine *soap = [[SOAPEngine alloc] init];
	soap.userAgent = @"SOAPEngine";
	soap.delegate = self; // use SOAPEngineDelegate

	// each single value
	[soap setValue:@"my-value1" forKey:@"Param1"];
	[soap setIntegerValue:1234 forKey:@"Param2"];
	// service url without ?WSDL, and you can search the soapAction in the WSDL
	[soap requestURL:@"http://www.my-web.com/my-service.asmx" 
		  soapAction:@"http://www.my-web.com/My-Method-name"];
 
	#pragma mark - SOAPEngine Delegates

	- (void)soapEngine:(SOAPEngine *)soapEngine didFinishLoading:(NSString *)stringXML {

	        NSDictionary *result = [soapEngine dictionaryValue];
        	// read data from a dataset table
        	NSArray *list = [result valueForKeyPath:@"NewDataSet.Table"];
	}
```

## Optimizations
---
First of all, if you note a slowdown in the response of the request, try to change the value of the property named `actionNamespaceSlash`.
After, when using the method named `requestWSDL` three steps are performed : 

1. retrieve the WSDL with an http request.
2. processing to identify the soapAction.
3. calls the method with an http request.

this is not optimized, very slow, instead you can use the optimization below : 

1. retrieving manually the SOAPAction directly from WSDL (once with your favorite browser).
2. use the method named requestURL instead of requestWSDL without WSDL extension.
