title: UITableView - How to change the background color of cell during drag drop?
body: <p>I'm implementing drag and drop between two UITableView's. 
  When dragging an item over tableView, the tableView automatically displays the space where the new cell will be inserted. I'd like to highlight that space by changing the background color. </p>
  
  <p>Currently, the space for the new cell shows in white. If I change the background color of UITableView, then the space reflects the corresponding background color. However, I do not want to change the background color for the tableView. </p>
  
  <p>Can someone help on how I can achieve it?</p>
  
  <p>Here's a screenshot of the functionality that I'm looking for.</p>
