title: Checkbox image toggle in UITableViewCell
body: <p>I need some guidance on creating a <code>UITableViewCell</code> that has an image on the left which can be toggled. The image should be tappable and act as a toggle (checkbox). </p>
  
  <p>My parts I'm struggling with are:</p>
  
  <ol>
  <li>How do I detect taps on the image and handle those differently to <code>didSelectRowAtIndexPath</code>?</li>
  <li>How do I change the image without performing a <code>[tableView reloadData]</code>?</li>
  </ol>
