从Swift 3发送电子邮件 [英] Sending an email from swift 3

问题描述

我正在尝试设置一个带有发送电子邮件"选项的应用程序.

I am trying to set up an app with send email option.

我有此代码:

import Foundation
import MessageUI
import UIKit

class emailClass: UIViewController, MFMailComposeViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        if !MFMailComposeViewController.canSendMail() {
            print("Mail services are not available")
            return
        }        
        sendEmail() 
    }

    func sendEmail() {      
        let composeVC = MFMailComposeViewController()
        composeVC.mailComposeDelegate = self
        // Configure the fields of the interface.
        composeVC.setToRecipients(["[e-mail]"])
        composeVC.setSubject("Hello!")
        composeVC.setMessageBody("Hello this is my message body!", isHTML: false)
        // Present the view controller modally.
        self.present(composeVC, animated: true, completion: nil)
    }

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

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

因此我收到此消息:邮件服务不可用". 现在，我已经在iCloud中登录了模拟器设备...所以我认为它应该这样做，但事实并非如此.为什么这不起作用?你能告诉我什么地方出了问题，我该如何前进?

So I get this message: "Mail services are not available". Now I've logged in the simulator device in iCloud... So i think it should do it but it's not. Why isn't this working? Can you tell me whats wrong and how can I move forward?

推荐答案

它不适用于模拟器.请在iPhone设备上进行测试.您可以引用 Apple开发人员门户-MFMailComposeViewController

It will not work with simulator. Please test it on iPhone device. You can refer Apple Developer Portal - MFMailComposeViewController
