我有一个应用程序，它使用 web 服务发布和获取数据，它工作正常，但是在严格测试应用程序时，应用程序因信号 9(Killed) 异常退出消息而崩溃。

我四处搜索，但找不到任何解决方案或杀死应用程序的原因。请帮助我解决问题。

编辑#2 在这里，我添加了一些代码，我的应用程序崩溃了。

 @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) {   
    }

你使用NSURLConnection不正确。如果你看这里，你可以看到你正在启动一个异步连接。看起来您在连接对象完成之前释放了它，这导致了分段错误。
