##DISCLAIMER

This library is still under construction. Beta testers are more than welcome.

PICO

A light Web Service client framework targeting iOS platform.

Feature Highlight

1. Support WSDL driven development, code generator tool is provided to auto-genearte strongly typed proxy from WSDL.
2. Support SOAP 1.1/1.2 and XML based web service.
3. Support automatic SOAP/XML to Objective-C object binding, performance is better than iOS native XML parser.
4. Built on popular and mature AFNetworking library for iOS.
5. Has been verified with industrial level Web Service like Amazon ECommerce Web Serivce and eBay Finding/Shopping/Trading Web Service.
6. Support asychronous service invocation, flexible HTTP/SOAP header setting, timeout setting, encoding setting, logging, etc.

The Big Picture

Adding Pico to Your Project

You have a few options:

####Include the whole Pico source in your project If you use this option, make sure:

1. In Target Build Setting, add the -ObjC flag to your "Other Linker flags".
2. In Target Build Setting, add /usr/include/libxml2 to your "Header Search Paths"
3. In Target Build Phases, link binary with library libxml2.dylib

####Add Pico xcodeproj to your project/workspace and reference Pico as a static library If you use this option, make sure:

1. In Target Build Setting, add the Pico source path to your "User Header Search Paths", choose "recursive" search path.
2. In Target Build Phases, link binary with library libxml2.dylib
3. In Target Build Phases, link binary with library libPico.a
4. You might also need to add Pico to the Traget Dependencies list.

##WSDL Driven Development Flow

1. Genearte Objective-C proxy from WSDL
2. Create new iOS project, add Pico runtime and generated proxy into your project
3. Implement appliction logic and UI, call proxy to invoke web service as needed.

##Example Usage After the service proxy is generated from wsdl, service invocation through Pico runtime is extremely easy:

        // start progress activity
        [self.view makeToastActivity];
        
        // Get shared service client
        StockQuoteServiceClient *client = [StockQuoteServiceClient sharedClient];
        client.debug = YES; // enable request/response message logging
        
        // Build request object
        GetQuote *request = [[[GetQuote alloc] init] autorelease];
        request.symbol = _symbolText.text;
        
        // make API call and register callbacks
        [client getQuote:request success:^(GetQuoteResponse *responseObject) {
            
            // stop progress activity
            [self.view hideToastActivity];
            
            // show result
            _resultText.text = responseObject.getQuoteResult;
        } failure:^(NSError *error, id<PicoBindable> soapFault) {
            
            // stop progress activity
            [self.view hideToastActivity];
            
            if (error) { // http or parsing error
                [self.view makeToast:[error localizedDescription] duration:3.0 position:@"center" title:@"Error"];
            } else if (soapFault) {
                SOAP11Fault *soap11Fault = (SOAP11Fault *)soapFault;
                [self.view makeToast:soap11Fault.faultstring duration:3.0 position:@"center" title:@"SOAP Fault"];
            }
        }];
