title: how to insert a landscape subview in portrait view,just like VEVO
body: <p>I have a tableview which I want it in portrait mode.And when I select a row, I want the subview in landscape mode, just like VEVO. In VEVO's videos, the tableView is only portrait,when select a row,the view is only landscape.</p>
  
  <p>As far as I knoow ,that</p>
  
  <p>A UINavigationController will only autorotate if its root view controller is also set to autorotate. 
  A UITabBarController will only autorotate if all of its view controllers are set to autorotate.</p>
  
  <p>so I cant use navigationController, am I right?
  so I can only use addsubview,but how it works?
  I set tableview  ==UIInterfaceOrientationPortait,and subview ==landscapeLeft||right,but subview is still not work correctly, what should I do?</p>
