title: Is there a way to know when the index on uitableview is actually used?
body: <p>Is there a way to know when the index on uitableview is actually used? I can’t find any methods in the Apple documentation, but I was wondering if anyone else knows anything. I would basically like to make an animation in my table view that changes depending on what section is selected in the index, and I have no idea how to do this without accessing the table view index.</p>
  
  <p>Any help is greatly appreciated.</p>
  
  <p>Thanks.</p>
