MFMessageComposeViewController让应用程序在关闭后重新加载？

Question

我有联系人表，逻辑用户将多选联系人发送短信邀请到应用程序，我的问题是在弹出短信撰写（关闭或发送）后，作曲家关闭并且应用程序已重启，是它的工作原理如何？为什么它应该重置应用程序我只是关闭或取消短信撰写控制器！

这就是我做的事情

//Send SMS
func sendSMS( to : [String] = [] , message : String = "" )
{

     if (MFMessageComposeViewController.canSendText())
     {
        let controller = MFMessageComposeViewController()
            controller.body = message
            controller.recipients = to

            if let topController = UIApplication.topViewController()
            {
                controller.messageComposeDelegate = topController as MFMessageComposeViewControllerDelegate
                topController.present(controller, animated: true, completion: nil)
            }
    }
}

    extension UIViewController: MFMessageComposeViewControllerDelegate {


        public func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
            switch (result.rawValue) {
            case MessageComposeResult.cancelled.rawValue:
                print("Message was cancelled")
                controller.dismiss(animated: true, completion: nil)
            case MessageComposeResult.failed.rawValue:
                print("Message failed")
                controller.dismiss(animated: true, completion: nil)
            case MessageComposeResult.sent.rawValue:
                print("Message was sent")
                controller.dismiss(animated: true, completion: nil)
            default:
                break;
            }
        }
    }

无论如何关闭短信作曲家而不重新加载应用程序？
