title: Hide navigation bar
body: <p>I have 3 views. (say 1st,2nd,3rd). I have pushed the 2nd view (which has a load view method) on the 1st. In the 2nd view I have created the 3rd using <code>initWithFrame</code> (which is inherited from UIWebView). In 2nd view I wrote self.view=3rd view. </p>
  
  <p>Now I want to hide the 2nd view's navigation bar in the 3rd view (i.e., when the user touch to 3rd view screen i.e. UIWebView). I got the touch recognition using gesture, but I can't hide the navigation bar. </p>
  
  <p>3rd view don't support <code>self.navigationController</code>. And if I create 2nd view's object in 3rd, it does not hide the navigation bar. Can anybody help me?</p>
