MFMailComposer邮件已发送回调

Question

我一直在捕捉图像和视频的应用程序，然后通过MFMailComposer发送到邮件。我已经创建了内容和大小约6MB的zip文件。我想要显示加载视图，当用户点击发送按钮和隐藏邮件控制器，当邮件实际发送时，我想通过警报显示消息。有什么办法可以做到吗？任何帮助都将不胜感激。

如果邮件已经发送，您可以使用MFMailComposeViewControllerDelegate方法获取信息：

- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{

    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Mail cancelled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Mail saved");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Mail sent");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Mail sent failure: %@", [error localizedDescription]);
            break;
        default:
            break;
    }

// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];
}

不要忘记将MFMailComposeViewControllerDelegate添加到.h文件中
