this is my implemenation file

Answer 1

You have to set Your Controller as delegate for MFMailComposeViewController like
if([MFMailComposeViewController canSendMail]) {
mail = [[MFMailComposeViewController alloc] init];
mail.mailComposeDelegate = self; //<-- Add this line
[mail setSubject:[NSString stringWithFormat:#"건의 및 문의"]];
[mail setToRecipients:email];
[self presentModalViewController:mail animated:YES];
[mail release];
}
And than you have to implement following delegate method. Thats it.
// From Here You can Dismisses the email composition interface when users tap Cancel or Send.
- (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:
NSLog (#"Result: sent");
break;
case MFMailComposeResultFailed:
NSLog (#"Result: failed");
break;
default:
NSLog (#"Result: not sent");
break;
}
[self dismissModalViewControllerAnimated:YES];
}
