title: How to rotate app with TabBar?
body: <p>Hi I have a splitview app that is working fine until I add a TabBar in the rootview section. The problem is that when I add the TabBar to the rootview the app does not rotate to landscape, if I change the orientation the view remains in portrait mode.
  How can I solve this?. Hope you can help</p>
