wait_fences：未能收到回覆：10004003錯誤發生時，點擊按鈕（發送，取消）MFmessgecompose模型iOS

Question

我想彈出MFMessageCompose模型（topviewcontroller）從另一個NSObject類方法，它是在後臺執行。

我彈出使用此代碼MFMessageCompose模式：

MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init]; 
if([MFMessageComposeViewController canSendText]) 
{ 
    controller.body = @"Check out FundooSpace for mobile.Download it now from app.fundoospace.net/FundooSpace/d"; 
    controller.recipients = (NSArray *)passa; 
    passa = nil; 
    AppDelegate * appDelegateObject1 = (AppDelegate *)[[UIApplication sharedApplication] delegate]; 
    controller.messageComposeDelegate = self; 
    [appDelegateObject1.navigationCntr.topViewController presentModalViewController:controller animated:NO]; 
} 

它工作正常。但是當我點擊發送或取消按鈕，然後應用程序獲取故障並給出錯誤是

wait_fences: failed to receive reply: 10004003 

請建議我。

我完全檢查了你的問題中包含的代碼，對我來說它正在設備上正常運行。

1）確保有委託在你的.h

@interface ViewController : UIViewController <MFMessageComposeViewControllerDelegate> 

2）你還實行委託方法在您的m：

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result { 
    NSLog(@"didFinishWithResult"); 

    // you have to deal with the result var 

    switch (result) { 
     case MessageComposeResultCancelled: 
      NSLog(@"Cancelled"); 
      break; 
     case MessageComposeResultFailed: 
      UIAlertView *alert = [[UIAlertView alloc] 
          initWithTitle:@"MyApp" 
           message:@"Unknown Error" 
           delegate:self 
         cancelButtonTitle:@」OK」 
         otherButtonTitles:nil]; 
      [alert show]; 
      [alert release]; 
      break; 
     case MessageComposeResultSent: 

      break; 
     default: 
      break; 
    } 

    [self dismissModalViewControllerAnimated:YES]; 
} 

3）如果你是on> iOS6.0「old」presentModalViewController：動畫已棄用，因此更改爲presentViewController：animated：completion：由於Xcode也指出了這一點。
