ios - "Please set up mail account in order to send email"Swift 错误

Question

我尝试通过我的应用程序发送电子邮件，但我收到一个名为

的错误

"Please set up mail account in order to send email".

我的代码块在下面。

import MessageUI

@IBAction func emailTapped(_ sender: Any) {   

    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)

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

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

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

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 }

        }

现在，在您的 iPhone 上搜索 Settings 应用程序，然后转到 Mail -> Accounts -> Add Account 在手机上设置电子邮件帐户。你可以看看这个video .
