IPHONE: ABPeoplePickerNavigationController hidden navigation bar
<p>Hello I have a ABPeoplePickerNavigationController, on creation is set its
navigationBar hidden.</p>

<pre><code>peoplePickerController.navigationBar.hidden = YES;
</code></pre>

<p>This works perfectly, the only problem is that when the user taps the search box
to search for a person, as he return's from the search, the navigationBar is re-displayed,.
How can I get notified of this and make the navigationBar hidden again ?</p>

<p>I also think this is an apple bug, since on regular cases when search is tapped,
the navigation bar is hidden to make for more room, and later displayed, but 
it does not take into account the fact that the bar could have been hidden in 
the first place.</p>

<p>Any trick's welcomed.</p>
