title: can't change subview position in UITableviewCell subclass
body: <p>I have a table. Table has 1 simple custom cell. There is only label in this cell.
  Here is code of cellForRow function:</p>
  
  <pre><code>MyCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
  
  cell.myLabel.text = [NSString stringWithFormat:@"%ld", (long)indexPath.row];
  cell.myLabel.frame = CGRectOffset(cell.myLabel.frame, 0, -20);
  cell.myLabel.backgroundColor = [UIColor redColor];
  
  return cell;
  </code></pre>
  
  <p>Everything works fine except this:</p>
  
  <pre><code>cell.myLabel.frame = CGRectOffset(cell.myLabel.frame, 0, -20);
  </code></pre>
  
  <p>Label don't want to move!
  I found this problem in iOS8.</p>
  
  <p>Anybody help please :)</p>
