title: Hide center tab bar button when pushed view sets HidesBottomBarWhenPushed
body: <p>I'm following the example on how to create a tab bar with a center button like Path,Instagram, etc from here: <a href="http://idevrecipes.com/2010/12/16/raised-center-tab-bar-button/">http://idevrecipes.com/2010/12/16/raised-center-tab-bar-button/</a></p>
  
  <p>The problem I have is that when a view is pushed onto the stack that sets HidesBottomBarWhenPushed to hide the tab bar, the center button is still displayed.</p>
  
  <p>In the comments, several other people have had this problem, but there's no working solution. (I've tried all the suggested solutions in the comments)</p>
  
  <p>I came up with a hacky solution-- store a reference to the center button in an unrelated singleton class, and then have the pushed view hide the button when it is loaded, and unhide it when it dissapears-- but this just feels wrong, and it looks funny because you can see the button dissapear before the push view animation starts.</p>
  
  <p>Has anyone got this working?</p>
