title: iOS - How to show a bar under navigation bar?
body: <p>My app have a navigation bar on the top, and a tab bar on botton, over a mapview. I need a way to filter some pins of the mapview. So, i`m trying to add a bar or something like that, under the navigation bar.</p>

  <p>This bar will have 2 text views and a button to perform the filtering job.
  I need this bar to be retractile by pressing a button on my navigation bar.</p>
  
  <p>If I run the project that way i get this:</p>
  
  <p><a href="http://localhostr.com/file/TfqlFnW/Captura%20de%20Tela%202012-02-02%20s%2011.22.07.png" rel="nofollow">http://localhostr.com/file/TfqlFnW/Captura%20de%20Tela%202012-02-02%20s%2011.22.07.png</a></p>
  
  <p>The bar is floating in the wrong place. =s</p>
  
  <p>I`m making it right? Or can I make it in another 'best' way?</p>
