title: Change the UITableView separatorColor for a single UITableViewCell
body: <p>I have a <code>UITableView</code> that uses a variety of custom <code>UITableViewCells</code>.</p>
  
  <p>I'd like to be able to have one of these table cells appear with a different separator color than the rest of the other cells.</p>
  
  <p>I know that <code>tableview.seperatorColor</code> updates the whole <code>tableView</code>. Is there a cell specific property I missing or another approach to doing this?</p>
  
  <p>Thanks for any tips. Sorry if I am just spacing on something in the <code>UITableViewCell</code> class.</p>
