    if MFMailComposeViewController.canSendMail() { 
     self.present(mailComposerVC, animated: true, completion: {() -> Void in }) 
    }

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Swift.Error?){

代码看起来不错（尽管可以改进），您需要在您使用的设备上设置您的电子邮件帐户。现在

import MessageUI 
    @IBAction func emailTapped(_ sender: Any) { 

      if MFMailComposeViewController.canSendMail() { 
       let mailComposerVC = MFMailComposeViewController() 
       mailComposerVC.mailComposeDelegate = self 
       mailComposerVC.setToRecipients(["abc@gmail.com"]) 
       mailComposerVC.setSubject("Sending you an in-app e-mail...") 
       mailComposerVC.setMessageBody("Sending e-mail in-app is not so bad!", isHTML: false) 

       self.present(mailComposerVC, animated: true, completion: {() -> Void in }) 
      } 

     } 

     func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Swift.Error?){ 
      controller.dismiss(animated: true) {() -> Void in } 

     }
