GKChallengeListener Protocol Reference

Overview

Provides methods for responding to challenge events. Your app can ignore a challenge, start up in a specific state so the player can respond to a challenge, or notify the original challenger when the local player completes a challenge.

Do not implement GKChallengeListener directly, instead use GKLocalPlayerListener. The GKLocalPlayerListener protocol inherits methods from GKChallengeListener, GKInviteEventListener, and GKTurnBasedEventListener in order to handle multiple events.
