title: Why does UITableViewCell flash on changing height?
body: <p>I have a simple UITableView with UITableViewCells. For the 0th row in the tableview, I have set a background color for the cell. Now on tapping the 0th row I just want the row to expand. In order to achieve this, I'm using the same technique as described <a href="https://stackoverflow.com/questions/4635338/uitableviewcell-expand-on-click">here</a> to change the 0th row height.</p>
  
  <p>Now the problem is that the cell expands and collapses, but with each process there's an ugly flash/flicker on the cell. I've tried both beginupdates/endupdates and also reloading just that single row using         <code>[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationNone];</code></p>
  
  <p>What's causing the flicker/flash on tapping? And how do I get rid of it? And yes, I forgot to mention, I have set the cell's selection style to none. So that's not causing this.</p>
