if ([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setSubject:@"Support Enquiry"];
[mailViewController setToRecipients:[NSArray arrayWithObject:EMAIL_SUPPORT]];
[self presentModalViewController:mailViewController animated:YES];
[mailViewController release];
}
My code crashes on the
MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
line with:

Any idea whats going on?
EDIT: All the answer so far have done nothing, it still crashes :(
EDIT 2: I finally figured out the problem - I had added a category to text field and MFMailComposeViewController did not like that at all.
As the asker reported on his question, MFMailComposeViewController uses some native elements that shouldn't be categorized. So, you have to be sure there aren't any categories on elements like UITextField or UITextView.
