View is not adjusting itself after hiding Tabbar
<p>I have a UITabbar having 5 tabs like this </p>

<p><img src="http://i.stack.imgur.com/0Ry80.png" alt="enter image description here"></p>

<p>Now I want to hide the UITabbar when taps on the Feed Tab. I want to show the full screen there. I am able to hide the tabbar but the UIView of Feed screen is not adjusting itself and I can see the white space at the place of UITabBar. I set the frame of view after hiding the UITabbar but it is also not working. How can I get the object of UITabbarController in the UIViewController classes which are added on the UITabbar so that I can call the delegate methods of UITabbarController. For instance, how can I have the object of UITabbarController in Feed Class.Please Help! If I am not clear please let me know.
Thanks-  </p>
