Estoy tratando de usar un servicio web de jabón que solo me devuelve una fecha (prueba). Pero no puedo conectarme con el servicio web. Solo recibo el wsdl del servicio web, pero no puedo obtener los datos deseados. El siguiente es mi código en el objetivo c

 NSString *soapMessage = @"<?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"
"<getDate xmlns:type=\"xsd:string\">\n"
"</getDate>\n"
"</soap:Body>\n"
"</soap:Envelope>\n";
NSURL *url = [NSURL URLWithString:@"http://10.1.6.5/gnosis2/public/wslogin/"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[req addValue:@"text/xml; charset=utf-8"  forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://10.1.6.5/gnosis2/public/wslogin/" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:req delegate:self];

Quiero usar el método getDate del servicio web. ¿Puede alguien ayudarme?

El código anterior me da el siguiente xml, que es el mismo que wsdl visto en el navegador:
