title: Why does the Tint of searchbar in UISearchDisplayController looks different than the tint for normal searchbar?
body: <p>This is what happen without settings. Notice that both tint is null. However they look different.</p>
  
  <p>I kind of like the whitish one on top though I cannot change the rest to that. The searchBar.tint is nil in all cases.</p>

  <p>Update: it must have something to do with the misterious UISearchBarBackground class.</p>
  
  <p>This is what happen if I remove them.</p>

  <p>(I remove code that set UITextFieldBackground so all of you can see that it's all part of apple stuff)</p>
