Question

我在使用SOAP的NSURLConnection中遇到问题，它在所有应用类中都能正常运行，但是在一个特定的类中它不起作用，一旦我调用[connection start];该应用程序不调用回调函数（委托函数），我确信我在主线程中运行并且请求正确，我真的需要帮助，谢谢。代码是：

if(!webData)
    webData = [[NSMutableData alloc] init];

NSString *soapMessage = [NSString stringWithFormat:
                         @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                         "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\n"
                         "<soap12:Body>\n"
                         "<ActivateUser xmlns=\"http://tempuri.org/\">\n"
                         "<UserID>%@</UserID>\n"
                         "<MelarityNo>%@</MelarityNo>\n"
                         "<Phone>%@</Phone>\n"
                         "<Name>%@</Name>\n"
                         "<Personal>%@</Personal>\n"
                         "<Rank>%@</Rank>\n"
                         "</ActivateUser>\n"
                         "</soap12:Body>\n"
                         "</soap12:Envelope>\n", @"", self.policeManID, self.policeManPhoneNum, @"", self.policeManPersonalID,@""];

NSURL* url = [NSURL URLWithString:@"link here.asmx"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLen = [NSString stringWithFormat:@"%d", [soapMessage length]];
[req addValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://tempuri.org/ActivateUser" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLen forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
if(con)
    con = nil;
con = [[NSURLConnection alloc] initWithRequest:req delegate:self];
[con start];

Answer 1

最有可能发生这种情况，因为NSURLConnection的委托在NSURLConnection有时间调用这些方法之前被释放。如果没有看到整个图片，我无法确定，但你必须看看代表何时被释放......

Answer 2

我不确定这是正确的解决方案，但出现的错误可能就是这样。

如果空格更改为

，则空格不会默认

NSURL* url = [NSURL URLWithString:@"link%20here.asmx"];
