Question

我有一个允许我发送电子邮件的应用程序。我已经知道了，因为在发送或取消按钮上键入后，邮件控制器已关闭。但是我想在应用程序内部安装一个“弹出窗口”或一些东西，告诉用户他们是否发送了邮件或取消了邮件。

注释掉的代码是我尝试让应用程序说出来的，但是由于一些警告，它无法正常工作。

    @IBAction func Senden(_ sender: Any) {
        let toRecipients = ["Mail@adress.com"]
        let mc: MFMailComposeViewController =       MFMailComposeViewController()
        mc.mailComposeDelegate = self
        mc.setToRecipients(toRecipients)
        mc.setSubject(FirmaFeld.text!)

        mc.setMessageBody("Firma: \(FirmaFeld.text!) \n\n Kontaktperson:  \(KontaktpersonFeld.text!) \n\n EMail: \(EMailFeld.text!) \n\n Anliegen:  \(NachrichtFeld.text!)", isHTML: false)
        self.present(mc, animated: true, completion: nil)
    }

    func mailComposeController(_ controller:  MFMailComposeViewController, didFinishWith result: MFMailComposeResult,  error: Swift.Error?) {
        controller.dismiss(animated: true, completion: nil)



        }




     /*   switch result.rawValue {
        case MFMailComposeResult.cancelled.rawValue:
            print("Mail cancelled")
        case MFMailComposeResult.saved.rawValue:
            print("Mail saved")
        case MFMailComposeResult.sent.rawValue:
            print("Mail sent")
        case MFMailComposeResult.failed.rawValue:
            print("Mail sent failure: %@",   [error!.localizedDescription])
        default:
            break
        }
        // Dismiss the mail compose view controller.
        self.dismiss(animated: true, completion: nil)

    }*/


    @IBAction func dismissKeyboard(_ sender: Any) {
         self.resignFirstResponder()
    }

我希望有人能帮忙（对不起英语）。

希望这对您有帮助

在完成区块内显示alertController。

controller.dismiss(animated: true, completion: {
if result == .cancelled {
        let alertController = UIAlertController(title: "E-Mail not sent!", message: "E-Mail not sent.", preferredStyle: .alert)

        alertController.addAction(UIAlertAction(title: "OK", style: .cancel, handler: { (action: UIAlertAction!) in
        }))

        present(alertController, animated: true, completion: nil)
    }
})

邮件发送方式相同。

如何让我的应用打印“电子邮件发送”或“电子邮件已取消”？
