title: Settings cell selected background view removes backgroundview
body: <p>I'm trying to set up custom <code>UITableViewCells</code>. I can set the backgroundView no problem, but if I set <code>selectedBackgroundView</code>, the cell's background becomes white and only the selected background is seen: </p>
  
  <pre><code>- (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row
  {
  UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cell_background_red.png"]];
  cell.backgroundView = bgImage;
  cell.selectedBackgroundView = bgImage;
  cell.textLabel.hidden = YES;
  
  UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(20, CGRectGetHeight(cell.frame) / 2, 200, 50)];
  titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey];
  titleLabel.backgroundColor = [UIColor clearColor];
  [cell.contentView addSubview: titleLabel];
  
  }
  </code></pre>
