title: tableviewcell separator moved in ios 8
body: <p>I'm creating tableviews and cells programmatically. The tableview cell separator moved in iOS 8, </p>
  
  <p><img src="https://i.stack.imgur.com/xjoU9.png" alt="enter image description here"></p>
  
  <p>even if I have already set:</p>
  
  <pre><code>-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      return kSomeNumber;
  }
  </code></pre>
  
  <p>My app is ios7 and my phone is ios8. What could be the problem?
  I can't use cell.layoutMargins which is for ios8 only</p>
