Question

我的项目的目的是拥有一个登录/创建帐户屏幕，用户点击一个按钮，用他们的用户名和电子邮件向他们发送电子邮件。密码验证它。

注意：用户名，密码和电子邮件是在我的项目的不同类中声明的全局变量编辑：有人说要在文件的末尾添加一些东西？那有什么意思？有人可以帮忙吗？

SendEmailToVerifyPassword类：

import UIKit
import MessageUI
class SendEmailToVerifyPassword: MFMailComposeViewController
{
    func ViewDidLoad()
    {
        super.viewDidLoad()
    }
    func configuredMailComposeViewController() -> MFMailComposeViewController {
        let mailComposerVC = MFMailComposeViewController()
        mailComposerVC.mailComposeDelegate = self // Extremely important to set the --mailComposeDelegate-- property, NOT the --delegate-- property

        mailComposerVC.setToRecipients([email])
        mailComposerVC.setSubject("Your password/username verification")
        mailComposerVC.setMessageBody("Hello.\n Your username is: \(username)\n Your password is \(password)", isHTML: false)

        return mailComposerVC
    }

    func showSendMailErrorAlert() {
        let sendMailErrorAlert = UIAlertView(title: "Could Not Send Email", message: "Your device could not send e-mail.  Please check e-mail configuration and try again.", delegate: self, cancelButtonTitle: "OK")
        sendMailErrorAlert.show()
    }

    func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {

        switch result.rawValue {

        case MFMailComposeResultCancelled.rawValue:
            print("Cancelled mail")
        case MFMailComposeResultSent.rawValue:
            print("Mail Sent")
        default:
            break
        }
        self.dismissViewControllerAnimated(true, completion: nil)
    }



}

Answer 1

class SendEmailToVerifyPassword: MFMailComposeViewController, MFMailComposeViewControllerDelegate
{
...
}

Swift xcode错误：“无法指定'SendEmailToVerifyPassword'类型的值来键入'MFMailComposeViewControllerDelegate？'
