How can I detect when the in-app MFMailComposeViewController has disappeared?

Question

I have set up some code to pull up MFMailComposeViewController so that users of the app can email people from within the app. How can I detect when this view controller has disappeared?

Thanks!

It may be useful to you.Here you can know which button he have pressed.So that you can know the mail composer displayed or not

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
{   
    // Notifies users about errors associated with the interface
    switch (result)
    {
        case MFMailComposeResultCancelled:
            //NSLog(@"Result: canceled");
            break;
        case MFMailComposeResultSaved:
            //NSLog(@"Result: saved");
            break;
        case MFMailComposeResultSent:
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Result" message:@"Mail Sent Successfully" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
            [alert show];
            [alert release];
        }
            break;
        case MFMailComposeResultFailed:
            //NSLog(@"Result: failed");
            break;
        default:
            //NSLog(@"Result: not sent");
            break;
    }
    [self dismissModalViewControllerAnimated:YES];
}
