In my iphone app, i've two view controllers. First one is a portrait and second one is landscape. When app is started, it will show the portrait view. On click of a button in portrait view, the view transitions to landscape view. Here, i'm using navigation controller. If both the views are portrait, pushing the next view via navigation controller won't be a problem. How can I achieve transition between portrait and landscape views using nav controller. Note that status bar is visible and nav bar is hidden.
