title: 2 UITableViews in one UIView
body: <p>I have a <code>UIView</code> that will need to display two UITableViews, but they are never shown together, by using a <code>SegementedBar</code> you can toggle one or the other.</p>
  
  <p>What would be the best way to handle this? Just create one <code>Table View Controller</code> and change the data source, or create 2 <code>Table View Controllers</code> and just hide one when the other is visible.</p>
  
  <p>The 2 tables will have a completely different layout with different custom cells.</p>
