iPhone應用程序在連接到遠程服務器時隨機崩潰？

-1

我有一個應用程序，發佈並獲取數據使用webservice它工作正常，但在測試應用程序嚴格崩潰的消息應用程序退出異常與信號9（殺死）。iPhone應用程序在連接到遠程服務器時隨機崩潰？

我googled左右，但我找不到任何解決方案或殺死app.please的原因幫我解決問題。

編輯＃2 在這裏，我添加了一些代碼，我在我的應用程序崩潰。

@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) { 
    }

很難說沒有看你的代碼。 – janusbalatbat 2012-07-24 11:23:39

爲什麼你發佈這個問題兩次，還有很多其他人發佈了相同的崩潰日誌。從那些舊的問題答案和提示開始，看看你能否更好地發現問題。 – rckoenes 2012-07-24 11:37:15

親愛的janusfidel，請參閱我的第二次編輯代碼，這裏是我懷疑崩潰的代碼片段。 – Srinivas4iPhone 2012-07-24 12:23:11
