NSString *msgLength = [NSString stringWithFormat:@"%d",[soapFormat length]];
[theRequest addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:@"GetUserList" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
//the below encoding is used to send data over the net
[theRequest setHTTPBody:[soapFormat dataUsingEncoding:NSUTF8StringEncoding]];

Creating simple SOAP requests are easy, however when you have complex graph of objects, dealing with Dictionaries and raw XML can be time consuming, WSClient++ generates Objective C source code for SOAP proxy with each complex type. You just make a single method call to retrieve results.
创建简单的 SOAP 请求很容易，但是当您有复杂的对象图时，处理字典和原始 XML 可能很耗时，WSClient++ 会为每个复杂类型的 SOAP 代理生成 Objective C 源代码。您只需调用一个方法即可检索结果。
