title: PresentModalViewController not showing TabBar
body: <p>I'm trying to go from one xib to another and I'm using TabBar.
  When I move from xib to xib with <code>PresentModalViewController</code> I lose the TabBar.</p>
  
  <p>When I use this way, it fail (like force close in android):</p>
  
  <pre><code>FirstViewController *fvc = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
      [fvc setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
      fvc.userSelectedLatitude = saveLatitude;
      fvc.userSelectedLongitude = saveLongtitude;
      UITabBarController *tabControl = [[UITabBarController alloc] initWithNibName:fvc bundle:nil];
      [self presentModalViewController:tabControl animated:NO];
  </code></pre>
  
  <p>When I use:</p>
  
  <pre><code>UITabBarController *tabControl = [[UITabBarController alloc] initWithNibName:@"FirstViewController" bundle:nil];
  </code></pre>
  
  <p>I get black screen with TabBar.</p>
  
  <p>Since it all fail I guess it is not the right way.
  So, what is the right way to do it?</p>
