GKAchievementViewController Class Reference
Available in iOS 4.1 and later.
GKAchievementViewController object provides a standard user interface to display achievement progress for the local player. If the
GKGameCenterViewController class is available, you should use it instead.
To show achievements for the local player, initialize a new
GKAchievementViewController object and set the delegate. Then present the new view controller and wait for the delegate to be called. Once the delegate is called, dismiss the view controller.
On iOS, you present and dismiss the view controller from another view controller in your game, using the methods provided by the
UIViewController class. On OS X, you use the
GKDialogController class to present and dismiss the view controller in a window.
GKAchievementViewController class is not intended to be subclassed.
Setting the Delegate
The achievement view controller’s delegate.
Your game must set the delegate before presenting the view controller.
