title: How to customize the background/border colors of a grouped table view cell?
body: <p>I would like to customize both the background and the border color of a grouped-style UITableView.</p>
  
  <p>I was able to customize the background color by using the following:</p>
  
  <pre><code>tableView.contentView.backgroundColor = [UIColor greenColor];
  </code></pre>
  
  <p>But the border color is still something I don't know how to change.</p>
  
  <p>How do I customize these two aspects of the grouped-style table view?</p>
