title: iPhone Three20 TTTableMoreButton Loading More Rows
body: <p>I've got an app called AppAdvice that seems to be using Three20.  I've noticed they have a mechanism in place within most of the tableviews that will automatically load more results when you scroll down to the bottom of the list and reveal the last row.  </p>
  
  <p>The also have an indicator in the last row that tells the user more items are loading then it disappears when the additional items are loaded.  Once the last row is revealed the app requests more results.</p>
  
  <p>Any clues on how they might be implementing this?  The thing I can't figure out is how to append items to a table view and reposition the indicator row.</p>
  
  <p>I know three20 has a tttablemorebutton, but I can't figure out how to use it.</p>
