title: Collection View iOS 7
body: <p>When i put my app in iOS 7, the top cell gets cover by my navigation bar.
  I tried using edgesForExtendedLayout but it just gives my an iOS 6 look of the app. 
  I'm trying to take advantage of the translucent bar in iOS 7 but edgesForExtendedLayout doesn't help.</p>
  
  <p>Is there a way to make this cell appear below de the navigation bar?</p>
