title: How to hide uitabbarcontroller
body: <p>I have a problem with <code>UITabBarController</code>. In my application, I want to hide it but without using <code>hidesBottomBarWhenPushed</code> because I want to hide it not when I pushed it. For Example, I want to hide it when I press a Hide button in my application. </p>
  
  <p>I read many articles in google but I cant find out how I can do this. </p>
