Question

I have an app that allows the user to send a test email from their iPhone. My app calls a method to activate the compose mail function like this:

-(void)displayComposerSheet
{

    //set up a way to cancel the email here
    //picker is an instance of MSMailComposeViewController already declared in the .h file

    [picker setSubject:@"Test Mail"];

    // Set up recipients

    // Attach an image to the email
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Icon" ofType:@"png"];
    NSData *myData = [NSData dataWithContentsOfFile:path];
    [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"Icon"];

    // Fill out the email body text
    NSString *emailBody = @"This is a test mail.";
    [picker setMessageBody:emailBody isHTML:NO];

    [self presentModalViewController:picker animated:YES];
    NSLog(@"mail is working");

}


- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    emailLabel.hidden = NO;
    // Notifies users about errors associated with the interface
    switch (result)
    {
        case MFMailComposeResultCancelled:
            emailLabel.text = @"Mail sending canceled.";
            break;
        case MFMailComposeResultSaved:
            emailLabel.text = @"Mail saved.";
            break;
        case MFMailComposeResultSent:
        {
            emailLabel.text = @"Mail sent.";
            NSLog(@"It's away!");


            UIAlertView *emailAlertView = [[UIAlertView alloc] initWithTitle:@"Sent!" message:@"Mail sent successfully." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
            [emailAlertView show];
            [self dismissModalViewControllerAnimated:YES];
            [self.navigationController popViewControllerAnimated:YES];


        }
            break;
        case MFMailComposeResultFailed:
        {
            emailLabel.text = @"Mail sending failed.";


        }
            break;
        default:
        {
            emailLabel.text = @"Mail not sent.";

        }
        break;
    }

}

My problem is that when the compose email function is active, I am unable to come out of this function and return to my app. The only way out of this is by actually going ahead and sending a message. There is a default “cancel” bar button that appears on the top left hand corner of the navigation bar, which when clicked, gives me three options: “delete draft”, “save draft”, and “cancel”. If I select “delete draft”, it does nothing except to return me to the compose message screen. Is there a way for me to allow the user to return to the app after starting the compose mail function, but prior to sending it? Is there a way to add extra functionality to the “cancel” bar button to accomplish this?

Thanks in advance to all who reply.

You have to implement MFMessageComposeViewControllerDelegate with the - (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result method.

You will dismiss your message view in this method.

EDIT : i confused with MFMailComposeViewControllerDelegate but the purpose is the same as with MFMessageComposeViewControllerDelegate
