title: gray line on top of UITableView iOS 5
body: <p>A strange gray line has appeared on the top of my UITableView in iOS 5 (was never present until I upgraded to Xcode 4.3 and am running app on iOS 5 iPhone) - has anyone else seen this?  I was also getting funny white lines in some of my other TableViewControllers that I got rid of by doing this:</p>
  
  <pre><code>    // needed to get rid of funny white lines in iOS 5
      tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
  tableView.separatorColor = [UIColor clearColor]; 
  </code></pre>
  
  <p>However, this does not work to remove this line.  There is no header title here. The line scrolls up and down with my UITableView
