title: Reusing a MFMailComposeViewController
body: <p>I have an app that is built on the TabBar-based app in which I need to have one tab that is basically an email composer.  So I'm trying to use a MFMailComposeViewController as one of the tabs.  This seems to work fine until I actually go to send an email with the controller.  If I do this the MFMailComposeViewController's view disappears and can't be used again.  </p>
  
  <p>If I'm reading the docs correctly, the MFMailComposeViewController is normally used modally, but it is supposed to work non-modally as well. </p>
  
  <p>This is how I am adding it to the tab bar...</p>
  
  <pre><code>MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
  mailController.title = @"Feedback";
  mailController.tabBarItem.image = [UIImage imageNamed:@"pencil.png"];
  [array addObject:mailController];
  tabBarController.viewControllers = array;
  </code></pre>
