title: Show/Hide TabBarController in iphone
body: <p>i am making an application in iphone in which i have 4 tabbars &amp; in one of its tab i have 4 views in 2nd view it needs to hide the tab bar. I am able to hide the tab bar using the setHidesBottomBarWhenPushed:YES in in the initWithNib method of the Viewcontroller being pushed. But when navigating to the screen 3 , calling the same method with "NO" does not make the tab bar appear. any ideas?</p>
