title: UITableViewCell makes label's background clear when highlighted
body: <p>I have a UIlabel on a UITableViewCell, which I've created programmatically (i.e. not a nib or a subclass).</p>
  
  <p>When the cell is highlighted (goes blue) it makes all the background colors of the UILabels turn clear. I have 2 UILabels where I don't want this to be the case. 
  Currently I'm using UIImageViews behind the UILabel's to make it look like the background color doesn't change. But this seems an inefficient way to do it.</p>
  
  <p>How can i stop certain UILabel's background color changing when the UITableViewCell is highlighted?</p>
