不能關閉Swift 3.0中的MFMailComposeViewController

按下取消或發送按鈕後不能解除MFMailComposeViewController。我在班上添加了MFMailComposeViewControllerDelegate，但仍然無法使用？不能關閉Swift 3.0中的MFMailComposeViewController

這裏是我的代碼：

func sendEmail() { 
    let MailVC = MFMailComposeViewController() 
    MailVC.mailComposeDelegate = self 
    MailVC.setToRecipients(["\(emailLabel?.text)"]) 
    MailVC.setSubject("Set your subject here!") 
    MailVC.setMessageBody("Hello this is my message body!", isHTML: false) 
    // Present the view controller modally. 
    self.present(MailVC, animated: true, completion: nil) 
} 

func mailComposeController(controller: MFMailComposeViewController, 
          didFinishWithResult result: MFMailComposeResult, error: NSError?) { 
    // Dismiss the mail compose view controller. 
    controller.dismiss(animated: true, completion: nil) 
}

檢查一次代表呼籲正確與否https://stackoverflow.com/questions/40305421/how-to-close-mfmailcomposeviewcontroller –

委託方法簽名是錯誤的。您在controller之前缺少_參數。嘗試這個。

public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { 
    // Dismiss the mail compose view controller. 
    controller.dismiss(animated: true, completion: nil) 
}

並確保這一點。

class ViewController: UIViewController ,MFMailComposeViewControllerDelegate
