Declaration
class UIStoryboard : NSObject
Overview
A storyboard represents the view controllers for all or part of your app’s user interface. Typically, view controllers in a storyboard are instantiated and created automatically in response to actions defined within the storyboard itself. However, you can use a storyboard object to instantiate the initial view controller in a storyboard file or instantiate other view controllers that you want to present programmatically.
