#autorotateMask ⇒ Object

You can use this method in ‘supportedInterfaceOrientations`, and it will query the stylesheet for the supported orientations, based on what orientations are defined. At a minimum, to opt-in to this feature, you’ll need to define styles like ‘style :root, landscape: true`

#autorotateToOrientation(orientation) ⇒ Object

This method used to be useful for the ‘shouldAutorotateToOrientation` method, but the iOS 6 update deprecates that method. Instead, use the `supportedInterfaceOrientations` and return `autorotateMask`.

restyles the view! be careful about putting styles in your stylesheet that you change in your controller. anything that might change over time should be applied in your controller using ‘style`
