title: UITableViewCell clear spacings
body: <p>I've got an UITableView with clear background color. The cells are made of:</p>
  
  <ol>
  <li>bckgrndView - slightly bigger to get spacing betweens cells</li>
  <li>-> contentView - contains content, set green</li>
  <li>-> -> label, textview - green too</li>
  </ol>
  
  <p>I set everything in interface builder (backgroundColor -> clear, opaque -> no), expect that i have to repeat 
  <code>cell.backgroundColor = [UIColor clearColor];
      cell.opaque = NO;
      cell.backgroundView = nil;
  </code> in <code>cellForRowAtIndexPath</code> or else, background would be white (bug?)</p>
  
  <p>But as soon as i scroll the clear color is gone and the spacing gets green(== same color as textview)
