title: Is it possible to refresh a single UITableViewCell in a UITableView?
body: <p>I have a custom <code>UITableView</code> using <code>UITableViewCell</code>s.
  Each <code>UITableViewCell</code> has 2 buttons. Clicking these buttons will change an image in a <code>UIImageView</code> within the cell.</p>
  
  <p>Is it possible to refresh each cell separately to display the new image?
  Any help is appreciated.</p>
