Question

我有一个ios iphone应用程序。该应用程序有一个主窗口xib，由标签栏和一个查看区域组成。还有一个称为订阅更新的xib，它由一个按钮组成，用户可以单击该按钮并发送电子邮件。此按钮弹出电子邮件窗口。在应用程序委托中，已加载订阅更新xib。订阅更新将添加为窗口rootViewController视图的子视图当用户单击“订阅更新”按钮时，将弹出邮件窗口。发送邮件或取消后，系统返回到应用程序。当返回时，我们发现只有订阅更新按钮是可单击的，主屏幕上的所有其他按钮都是不可单击的。订阅更新按钮将其位置移到左上角。附有屏幕截图。

只有订阅更新按钮可以单击。

            case MFMailComposeResultSaved:
                //Email saved
                break;
            case MFMailComposeResultCancelled:
                //Handle cancelling of the email
                break;
            case MFMailComposeResultFailed:
                //Handle failure to send.
                break;
            default:
                //A failure occurred while completing the email
                break;
        }
        [self becomeFirstResponder];
        [self dismissViewControllerAnimated:true completion:nil];

我尝试重新排序视图，特别是订阅更新视图。没啥事儿。我尝试过在邮件弹出后隐藏订阅更新视图，在这种情况下，主屏幕上的按钮开始起作用。

调用邮件ui后，iphone App屏幕上的按钮无响应，并在发送或取消后返回到应用程序
