title: MFMailComposeViewController canSendMail change alert if returned no
body: <p>I use MFMailComposeViewController canSendMail in my app everything works great but if there are no accounts on the iPhone or iPad it returns a standard alertview what I would like to change. If I put a alert in the else it will return 2 alerts. Is there a way to change the standard alert it returns? Or at least change the text in it?</p>
  
  <pre><code>MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
  if ([MFMailComposeViewController canSendMail]) {
      controller.mailComposeDelegate = self;
      controller.navigationBar.tintColor = [UIColor grayColor];
      NSArray *toRecipients = [NSArray arrayWithObject:@"info@info.nl"];
      [controller setToRecipients:toRecipients];
      [controller setSubject:@"bericht van info"];
      [self presentModalViewController:controller animated:YES];
      [controller release];
  }
  else {
  
  }
  </code></pre>
