Discussion
Do not call this method directly. The system calls this method during the state restoration process so that you can restore your view controller to its previous state.
If your app supports state restoration, override this method for any view controllers for which you also overrode the encode method. Your implementation of this method should use any saved state information to restore the view controller to its previous configuration. If your encode method called super, this method should similarly call super at some point in its implementation.
