Question

我尝试在我的应用程序中发送电子邮件时实施MFMailComposeViewController。问题是，在提交MFMailComposeViewController之后，它并没有被＆＃34;取消＆＃34;或＆＃34;发送＆＃34;按钮，只是稍微向上滚动。

以下是它的介绍：

func mailButtonDidPressed {
        let emailTitle = "Test email"
        let messageBody = "some body bla bla bla"
        let toRecipents = "email@gmail.com"

        let emailComposer = MFMailComposeViewController()
        emailComposer.setSubject(emailTitle)
        emailComposer.setMessageBody(messageBody, isHTML: false)
        emailComposer.setToRecipients([toRecipents])
        emailComposer.mailComposeDelegate = self
        self.presentViewController(emailComposer, animated: true, completion: nil)
    }

并解雇委托代码：

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
    switch (result) {
    case MFMailComposeResultSent:
        print("You sent the email.")
        break
    case MFMailComposeResultSaved:
        print("You saved a draft of this email")
        break
    case MFMailComposeResultCancelled:
        print("You cancelled sending this email.")
        break
    case MFMailComposeResultFailed:
        print("Mail failed:  An error occurred when trying to compose this email")
        break
    default:
        print("An error occurred when trying to compose this email")
        break
    }

    controller.dismissViewControllerAnimated(true, completion: nil)
}

我浏览过StackOverflow和其他类似的服务，但找不到任何答案。

Answer 1

如果有任何人在Swift 3.0中遇到此问题，我认为MFMailComposeViewController可能有两种类似于CORRECT方法的方法。

确保使用此方法

  func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        controller.dismiss(animated: true, completion: nil)
    }

Answer 2

对于swift 3你必须添加

        composer.mailComposeDelegate = self as MFMailComposeViewControllerDelegate

Answer 3

我解决了以这种方式删除completion的写法：

extension UIViewController: MFMailComposeViewControllerDelegate {

    func sendEmail() {
      //send email
    }

    public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        controller.dismiss(animated: true)
    }

}

记住要添加两个代表：

emailComposer.mailComposeDelegate = self
emailComposer.delegate = self

如果仅添加一个，则不会关闭。还要确保实现委托方法：

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
    dismiss(animated: true)
}

Answer 5

假设mailComposeControllermailComposeController是与mailButtonDidPressedmailButtonDidPressed相同的类的函数，它应该是它关闭MFMailComposeViewController的实例，所以

self.dismissViewControllerAnimated(true, completion: nil)

而不是

controller.dismissViewControllerAnimated(true, completion: nil)

Answer 6

您没有添加委托：

emailComposer.delegate = self

你的代码应该是这样的：

func mailButtonDidPressed {
        ...

        let emailComposer = MFMailComposeViewController()
       emailComposer.delegate = self 

...
    }

Answer 7

我遇到了这个问题，答案非常简单。一定要包括

MFMailComposeViewControllerDelegate

在顶部，就像列出您的遗产一样，然后包含其他答案中的内容。

MFMailComposeViewController不会被忽略
