title: background image pixelated
body: <p>I want a background image on my grouped UITableView, so I used the code:</p>
  
  <pre><code>self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"imageName.png"]];
  </code></pre>
  
  <p>But the image is pixelated. I think I want to change the content mode, but since it is not a UIImageView... I can't seem to do it.</p>
  
  <p>Is there another way to make a background image for a UITableViewController out of a UIImageView? </p>
