在Game Center中正确响应远程玩家退出

Question

我有两个参与者,基于回合的比赛一个和乙.这是目前一个轮到.B通过致电退出:

[match participantQuitOutOfTurnWithOutcome:GKTurnBasedMatchOutcomeQuit ... etc.

至于一个的游戏中心的应用程序而言,与之相匹配的乙仍然在发挥作用-比赛状态GKTurnBasedMatchStatusOpen,而比赛的结果是GKTurnBasedMatchOutcomeNone和GKTurnBasedMatchOutcomeQuit分别.

从文档中可以看出,参与者A应该检测到这一点并致电:

participantA.matchOutcome = GKTurnBasedMatchOutcomeWon;
participantB.matchOutcome = GKTurnBasedMatchOutcomeQuit;

[self endMatchInTurnWithMatchData: ... etc.

然而,似乎没有任何通知participantQuitOutOfTurnWithOutcome,并且定期迭代每场比赛以结束转弯感觉就像一个kludge.

结束这些比赛的正确方法是什么？

Answer 1

它有一个很好的解决方案:)

首先,你设置一个处理程序

[GKTurnBasedEventHandler sharedTurnBasedEventHandler].delegate = self;

之后,您将获得回调

handleInviteFromGameCenter:
handleTurnEventForMatch:didBecomeActive:
handleMatchEnded:
handleTurnEventForMatch:didBecomeActive:
handleTurnEventForMatch:didBecomeActive:
player:receivedExchangeRequest:forMatch:
player:receivedExchangeCancellation:forMatch:
player:receivedExchangeReplies:forCompletedExchange:forMatch:

你需要这种方法

handleMatchEnded:

处理对手方的比赛结束.
