我googled左右，但我找不到任何解决方案或杀死app.please的原因帮我解决问题。

编辑＃2 在这里，我添加了一些代码，我在我的应用程序崩溃。

@try { 

    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; 

    NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults]; 

    NSString *string = [NSString stringWithFormat:URL]; 

       NSURL *url = [NSURL URLWithString:string]; 
      NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: url]; 
       // NSURLRequest *request =[NSURLRequest requestWithURL:[NSURL URLWithString:synStr]]; 
      NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
      [connection start]; 
      [connection release]; 
      if(label != nil){ 
     progressView = [[ProgressView showHUDAddedTo:self.tabBarController.view animated:YES]retain]; 
     progressView.labelText = label; 
     } 

     [request release]; 
      } 
    @catch (NSException * e) { 
    }

很难说没有看你的代码。 – janusbalatbat 2012-07-24 11:23:39

为什么你发布这个问题两次，还有很多其他人发布了相同的崩溃日志。从那些旧的问题答案和提示开始，看看你能否更好地发现问题。 – rckoenes 2012-07-24 11:37:15

亲爱的janusfidel，请参阅我的第二次编辑代码，这里是我怀疑崩溃的代码片段。 – Srinivas4iPhone 2012-07-24 12:23:11

答

您错误地使用了NSURLConnection。如果你看看here，你可以看到你正在开始异步连接。看起来您在连接对象完成之前释放连接对象，这导致了分段错误。
