title: Overlay tabbar with a view
body: <p>I have a <code>UIViewController</code> inside Tab bar. For one VC in Tab bar I allow the interface to rotate upon device rotation. The challenge is, that I want to hide the Tab bar and resize my view inside.</p>
  
  <p>What I did:</p>
  
  <p>1) called <code>- (void)willAnimateRotation....</code> in my Tab bar controller and set <code>self.tabBar.isHidden</code> to true -> the Tab bar disappeared.</p>
  
  <p>2) called <code>- (void)willAnimateRotation....</code> and set <code>self.mapView.frame</code> to maximum height.</p>
  
  <p>BUT...I still have a black stripe in the bottom of the screen in exact size of the tab bar. Is there a way how to make the tab bar disappeat completely?</p>
