Search Display Controller to not hide navigation bar when search bar is tapped
<p>I use Search Display Controller to do the search. I follow the TableSearch sample from Apple.</p>

<p>In <code>searchBarTextDidBeginEditing</code> I put <code>[self.searchDisplayController setNavigationBarHidden:NO animated:YES]</code> to keep navigation bar showing, but this doesn't work. Navigation bar gets pushed to the top when the keyboard shows.</p>

<p>Is there a way to keep navigation bar staying on the page when the keyboard is first shown?</p>

<p>Thanks</p>
