ios - 其 View 不在 NSNotification 中的窗口层次结构中

我有错误 其 View 不在窗口层次结构中!

当我是 NSnotification 时

- (void) receiveTestNotificationNSNotification *) notification
{


    if ([[notification name] isEqualToString"TestNotification"])
        NSLog (@"Successfully received the test notification!");


    UIStoryboard *storyboard = [UIStoryboard storyboardWithName"Main" bundle:nil];
    mainTabViewController *vc = [storyboard instantiateViewControllerWithIdentifier"passID"];
    [vc setModalPresentationStyle:UIModalPresentationFullScreen];

    [self presentViewController:vc animated:YES completion:nil];

}

如果您想在单元格内显示事件 View ，
也许在标题旁边，你可以使用类似的东西，

 UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc]     initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
  [cell.imageView addSubview:activityView];
  [activityView startAnimating];
