title: Position UITableViewCell on Top when Cell is selected
body: <p>I want that the selected cell will always be at the top most position of <code>tableView</code>.
  I can to it via:  </p>
  
  <pre><code>[tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
  </code></pre>
  
  <p>but my problem is, when the number of cells, for example, is just 3. When I select cell number 3, it just stays there. Was that the normal behaviour? If yes, then, can you suggest something so that I can achieve my goal? Thanks!</p>
