title: Make UIButton accessible (accessibility) in tableview header
body: <p>I don't seem to be able to find anyone that has the same issue as me. All my tableview cells are perfectly fine for accessibility but my headers don't seem to. I have a button in my header view which just won't work for accessibility... Can anyone help me out with this?</p>
  
  <pre><code>- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
  
  
      UIButton *button = [[[UIButton alloc] initWithFrame: CGRectMake(282, 10, 28, 28)] autorelease];
      button.isAccessibilityElement = TRUE;
      button.titleLabel.text = @"Informatie";
  
      [button addTarget:self action:@selector(infoButtonAction:) forControlEvents:UIControlEventTouchUpInside];
      [cell addSubview:button];
  }
  </code></pre>
  
  <p>I realise that I paraphrased this horribly. What I mean is, the button is working and all, just not for users that have assistive touch enabled on their phones. The phone isn't 'showing up' with the voice that helps the disabled users out. 
  And I do get the log error "AX ERROR: Could not find my mock parent, most likely I am stale."</p>
