title: Expandable UITableView Sticking
body: <p>I am creating an expandable UITableView.  It works fine but the issue I am running into is when a given row is expanded and the user scrolls up, the opened section row scrolls up to the top of the visible table and stick.</p>
  
  <p><a href="https://i.stack.imgur.com/RdWPG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RdWPG.png" alt="The section row expands showing the detail material"></a></p>
  
  <p>In the below image, the detail row material and the succeeding section rows scroll OVER the opened section row.</p>

  <p>I would expect that the section row would scroll off the top of the visible table view.</p>
  
  <p>Am I missing something that would allow the section row to scroll up rather than stick?</p>
