原标题:Dismiss mailComposeController

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.

什么是错?

- (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.
}
最佳回答

您可取代这一行文:

[self dismissModalViewControllerAnimated:YES];

a. 符合以下规定:

[controller dismissModalViewControllerAnimated:YES];

班级继承<条码> 航程,因此其代表的财产被授予导航控制员部分。 为了处理具体的邮件 compos,你需要把标语定为<条码>。 财产:

mailComposer.mailComposeDelegate = self;

SWIFT 5.0:

如果你执行MFmailComposeViewController 代表礼宾司只须在主计长办公室内承担以下职能:

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

This function handles everything for you. If the user sends the email the view disappears automatically. Any further information: mailComposeController
