xcode - 如何让应用程序发送电子邮件？

Question

我在网上和这个网站上找到了代码。

我已经更新了弃用的部分。

邮件似乎已发送但从未出现。是否需要在应用程序外部的某处设置某些内容，或者代码是否有问题。应用程序有一个发送电子邮件的按钮。

import Foundation
import UIKit
import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate {

@IBAction func pressedSendMail(sender: AnyObject) {
    let mailComposeViewController = configuredMailComposeViewController()
    if MFMailComposeViewController.canSendMail() {
        self.presentViewController(mailComposeViewController, animated: true, completion: nil)
    } else {
        self.showSendMailErrorAlert()
    }
}

func configuredMailComposeViewController() -> MFMailComposeViewController {
    let mailComposerVC = MFMailComposeViewController()
    mailComposerVC.mailComposeDelegate = self // Extremely important to set the --mailComposeDelegate-- property, NOT the --delegate-- property

    mailComposerVC.setToRecipients(["myemail@hotmail.com"])
    mailComposerVC.setSubject("Sending you an in-app e-mail...")
    mailComposerVC.setMessageBody("Sending e-mail in-app is not so bad!", isHTML: false)

    return mailComposerVC
}

func showSendMailErrorAlert() {
    let alert = UIAlertController(title: "Could Not Send Email",
        message: "Your device could not send e-mail.  Please check e-mail configuration and try again.",
        preferredStyle: .Alert)
    let action = UIAlertAction(title: "OK",
                               style: .Default,
                               handler: nil)
    alert.addAction(action)
    presentViewController(alert, animated: true, completion: nil)
}

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
    controller.dismissViewControllerAnimated(true, completion: nil)
}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

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

}

与电话和相机应用程序类似，电子邮件应用程序不会在模拟器中打开。您需要在物理设备上对其进行测试才能对其进行测试。通过查看您提供给我们的代码，它应该可以正常工作。只需连接您的 iPhone 或其他 Apple 设备并在其上运行即可查看其工作情况。
