body: <p>Why doesn't UITableViewCell background color work (set in interface builder)?</p>
  
  <p>I note from some searching that the follow code set in your custom subclass of UITableViewController does work (see below):</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
      cell.backgroundColor = [UIColor redColor];
  }
  </code></pre>
  
  <p>But I would still like to just understand why interface builder has a background color setting for the TableViewCell, which effectively doesn't seem to work?</p>
