[mailViewController setMailComposeDelegate:self];
[mailViewController setToRecipients:[NSArray arrayWithObject:MAIL_EMAIL]];
[mailViewController setSubject:MAIL_SUBJECT];
[mailViewController setMessageBody:MAIL_MESSAGE isHTML:NO];
[self presentViewController:mailViewController animated:YES completion:^{
}];
Mail Composer Delegate Method :-
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(#"Mail cancelled");
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved");
break;
case MFMailComposeResultSent:
NSLog(#"Mail sent");
break;
case MFMailComposeResultFailed:
NSLog(#"Mail sent failure: %#", [error localizedDescription]);
break;
default:
break;
}
[controller dismissViewControllerAnimated:YES completion:^{
}];

Answer 1

Add the following code to your UIViewController subclass (the one you're using to present the mail composer)
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
-(BOOL)shouldAutorotate
{
return NO;
}
