关闭邮件ComposeController
如果用户发送或取消，我会在完成后尝试从我的应用程序中忽略邮件。 但出于某种原因，这永远不会被忽视。我几乎尝试了一切。 我也记录了这个，所以我会看看它是否进入了解雇方法。问题就在那里，因为它永远不会进入解雇方法。
我做错了什么？？？
- (IBAction)sendmail:(id)sender{
UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * imageData = UIImageJPEGRepresentation(image, 1.0);
if ( [MFMailComposeViewController canSendMail] ) {
MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc] init];
mailComposer.delegate = self;
[mailComposer addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"attachment.jpg"];
[mailComposer setSubject:@"Hello from My App!"];
NSString *emailBody = @"Sent from My App, Still not in AppStore!";
[mailComposer setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:mailComposer animated:YES];
}
}
-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self dismissModalViewControllerAnimated:YES];
NSLog (@"mail finished"); // NEVER REACHES THIS POINT.
}
I am trying to dismiss the mail from my app after it's done if user sends or cancels.
But for some reasone this never dismisses. I tried almost everything.
I have also logged this so I will see if it went to dissmiss method. And the problem is there since it never enters the dismiss method.
What am i doing wrong???

MFMailComposeViewController 类继承自 UINavigationController ，因此它的委托属性是该类的导航控制器“部分”的“委托”。要处理特定的邮件编辑器委托方法，您需要将对象设置为
mailComposeDelegate属性：MFMailComposeViewControllerclass inherits fromUINavigationControllerand so its delegate property is 'delegate' for navigation controller 'part' of the class. To handle specific mail composer delegate methods you need to set your object asmailComposeDelegateproperty:SWIFT 5.0：
如果您实现 MFMailComposeViewControllerDelegate 协议，则只需在 ViewController 中包含以下函数：
该函数会为您处理所有事情。如果用户发送电子邮件，视图将自动消失。
任何进一步的信息：
mailComposeController
SWIFT 5.0:
If you implement the MFMailComposeViewControllerDelegate protocol, you only have to contain the following function in ViewController:
This function handles everything for you. If the user sends the email the view disappears automatically.
