这段时间，一直都在搞 webService 编程和 socket 编程，搞的死去活来的。总算是有点了解和认识，现在作笔录：<p>一，webService源代码</p>        NSString *url = [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><%@ xmlns=\"http://www.zgbeidou.cn/\"><username>%@</username><password>%@</password>
<servicepassword>YFGPS2008</servicepassword></%@></soap:Body></soap:Envelope>",type,nil,nil,type];

 NSString *urlLength = [NSString stringWithFormat:@"%d",[url length]];

 [urlRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

 [urlRequest addValue:urlLength forHTTPHeaderField:@"Content-Length"];

 NSString *SOAPAction_str = [NSString stringWithFormat:@"http://www.zgbeidou.cn/%@",type];

 [urlRequest addValue:SOAPAction_str forHTTPHeaderField:@"SOAPAction"];

 [urlRequest setHTTPMethod:@"POST"];

 [urlRequest setHTTPBody:[url dataUsingEncoding:NSUTF8StringEncoding]];

 //请求并接收返回的数据 

 NSURLResponse *reponse;

 NSError *error = nil;

 NSData *responseData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&reponse error:&error];

 NSMutableString *resultString = [[NSMutableString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];

 //    NSLog(@"urlRequest = %@",resultString);

 //解析xml数据

 GDataXMLDocument *doc = [[GDataXMLDocument alloc]initWithData:responseData options:0 error:nil];

 GDataXMLElement *rootElement = [doc rootElement];
 
    NSData *data = [[rootElement stringValue]dataUsingEncoding:NSUTF8StringEncoding];

 NSArray *arr = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];

 NSLog(@"arr11111 = %@",arr );
