GKChallengeListener
An object that responds to challenge events.
Declaration
protocol GKChallengeListener : NSObjectProtocolOverview
Your game can ignore a challenge, start up in a specific state so the local player can respond to a challenge, or notify the challenger when the local player completes a challenge.
Don’t implement GKChallengeListener directly; instead use GKLocalPlayerListener. The GKLocalPlayerListener protocol inherits methods from GKChallengeListener, GKInviteEventListener, GKSavedGameListener, and GKTurnBasedEventListener in order to handle multiple events.
