title: slightly different scrolling needed after searching
body: <p>I have a UISearchBar below a header-view. This header is 64px hight. If the searchbar gets touched, the parent view will move 64px up — fine.</p>
  
  <p>After finishing searching the parent view will only move down, as long there is still free space below it. And the top is out of the visible bounds.</p>
  
  <p>But I want to move it back to the original position every time searching finished. How can I achieve it?</p>
