title: UITableView change header title color
body: <p>I'm styling the UITableView in <a href="http://InAppSettingsKit" rel="noreferrer">InAppSettingsKit</a> and want to change the color of the header title:</p>
  
  <p><img src="https://i.stack.imgur.com/mDDwG.png" alt="image of tableview"></p>
  
  <p>The labels <code>Without title</code> and <code>Text Field</code> should be white. How can this be done?</p>
  
  <p>Thanks.</p>
