Unable to access SOAP service built on WCF on iPhone - ios

Question

I am trying to access a WCF service from a iPhone app but I am getting following error:
AFHTTPRequestOperation error: Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: internal server error (500)" UserInfo=0x8c75b90 {NSErrorFailingURLKey=http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc, AFNetworkingOperationFailingURLResponseErrorKey= { URL: http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc } { status code: 500, headers {

"Content-Length" = 736;
"Content-Type" = "text/xml; charset=utf-8";

"X-AspNet-Version" = "4.0.30319";
"X-Powered-By" = "ASP.NET";
} }, NSLocalizedDescription=Request failed: internal server error (500)}
Following is my code to access the service:
NSURL *baseURL = [NSURL URLWithString:#"http://xxx.xxx.xx.xxx/accessserviceshost/servicecontroller/holdingslistservice.svc"];
NSString *soapBody = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
"<soap:Body><HoldingsListInput xmlns=\"http://tempuri.org/\">"

"<Unique_Assets_Only_Cd>Y</Unique_Assets_Only_Cd>"
"<Very_Liquid_Asset_Classes_Cd>X</Very_Liquid_Asset_Classes_Cd>"
"</HoldingsListInput></soap:Body></soap:Envelope>"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:baseURL];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[soapBody dataUsingEncoding:NSUTF8StringEncoding]];
[request addValue:#"http://tempuri.org/RetrieveHoldingList" forHTTPHeaderField:#"SOAPAction"];
[request addValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"%#", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"%s: AFHTTPRequestOperation error: %#", __FUNCTION__, error);
}];
[operation start];
I have checked service with same input on an asp.net page and it works there but I am not able to run it on the iPhone app.

-Try This way . IT might help. Edit your Soap Request string in this manner , may be problem lies in that .
NSString *soapRequest =[NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<Login xmlns=\"http://tempuri.org/\">\n"
"<UID>%#</UID>\n"
"<Password>%#</Password>\n"
"</Login>\n"
"</soap:Body>\n"
"</soap:Envelope>\n",#"Test",#"Test"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request addValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"http://tempuri.org/RetrieveHoldingList" forHTTPHeaderField:#"SOAPAction"];
NSString *msgLength = [NSString stringWithFormat:#"%lu",(unsigned long)[soapRequest length]];
[request addValue:msgLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[soapRequest dataUsingEncoding:NSUTF8StringEncoding]];

SOAPUI came to my rescue. There was a flaw in the JASON. I used SOAPUI to build request and other parameters need for it and it worked fine for me.
