Question

我在网站和本网站上找到了代码。

我更新了已弃用的部分。

邮件似乎已发送但从未出现过。是否需要在应用程序外部设置某些内容或代码是否有问题。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.
}

}

Answer 1

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。从你给我们的代码看它应该工作正常。只需连接您的iPhone或其他Apple设备，然后在那里运行即可查看它。

Answer 2

我正在测试一台设备（iPad mini），它不仅仅是没有发送电子邮件。原来我从未发过这个设备的电子邮件。所以邮件没有设置好。 iPhone会在这种情况下发出警告，而iPad则没有。如果您遇到类似问题，请检查您的用户是否已从设备发送电子邮件，而不仅仅是设备上的网络浏览器。

如何让应用发送电子邮件？
