GKTurnBasedMatch接收数据 [英] GKTurnBasedMatch receive data

问题描述

我正在尝试实现基于回合的应用程序，并且发送回合数据没有问题，但是我看不到自动接收数据的方法.到目前为止，我发现了很多:

I am trying to implement a turn-based app, and there is no problem with sending turn data, but I see no way of receiving data automatically. So far, I have found out that much:

• 有一个GKTurnBasedEventHandlerDelegate协议.这很容易实现，但是我应该在哪里将该对象设置为必须委托的对象呢?它似乎不是GKTurnBasedMatch，GKTurnBasedMatchmakerViewController或GKMatchMaker的委托.

• There is a GKTurnBasedEventHandlerDelegate-protocol. It is easy to implement, but where do I set that object to be a delegate of whatever it has to be a delegate of? It does not seem to be a delegate of GKTurnBasedMatch, or GKTurnBasedMatchmakerViewController, or GKMatchMaker.

还有一种GKTurnBasedMatch的方法，称为loadMatchDataWithCompletionhandler，但是据我所知，当您有点直觉认为需要更新比赛时，它只会被调用一次.我怎么知道它必须更新?我是否必须每秒左右触发一次此功能?

There is also a method of GKTurnBasedMatch which is called loadMatchDataWithCompletionhandler, but, as far as I understand, it is only called once when you kinda have a gut feeling that the match needs to be updated. How am I to know that it has to be updated? Do I have to fire this function every second or so?

谢谢.

更新:我已经将[GKTurnBasedEventHandler sharedTurnBasedEventHandler].delegate设置为实现GKTurnBasedEventHandlerDelegate的静态实例.它仍然永远不会被调用.

UPDATE: I have set [GKTurnBasedEventHandler sharedTurnBasedEventHandler].delegate to be a static instance that implements GKTurnBasedEventHandlerDelegate. It still never gets called.

推荐答案

使用以下语句设置它，它将成为共享实例的委托:

You set it with below statement, it becomes the delegate of a shared instance:

[[GKTurnBasedEventHandler sharedTurnBasedEventHandler] setDelegate:self];

您实际上不需要手动呼叫loadMatchDataWithCompletionhandler，当其中一位参与者呼叫endTurnWithMatchData时，所有其他参与者都将通过GKTurnBasedEventHandler委托方法得到通知:

You do not need to call loadMatchDataWithCompletionhandler manually actually, when one of the participants call endTurnWithMatchData all other participants will be notified through GKTurnBasedEventHandler delegate method:

-(void) handleTurnEventForMatch:(GKTurnBasedMatch *)match didBecomeActive:(BOOL)didBecomeActive

那是您需要更新UI的地方.请注意，模拟器不支持GKTurnBasedEventHandler委托方法，它们只会在实际设备中被调用.

That's where you need to update UI. Beware that simulator does not support GKTurnBasedEventHandler delegate methods, they only get called in actual devices.
