Time for action – laying down the rules

We'll update the RootViewController.mm file.

1. Go to RootViewController.mm inside the ios folder and look for the shouldAutorotateToInterfaceOrientation method. Change the line inside the method to read:

   return UIInterfaceOrientationIsPortrait( interfaceOrientation );

2. And a few lines below in the supportedInterfaceOrientations method, change the line inside the conditional to:

   return UIInterfaceOrientationMaskPortrait;

What just happened?

We just told RootViewController we want our application to play in any of the two supported portrait modes.
