这是关于GameCenter。

由于“GKLocalPlayerListener协议继承了GKChallengeListener,GKInviteEventListener和GKTurnBasedEventListener.

为了处理多个事件”和“不要直接实现GKChallengeListener, GKInviteEventListener, 和GKTurnBasedEventListener；GKLocalPlayerListener改为实施。

您可以使用 " 侦听和处理多个事件GKLocalPlayerListener（这些来自苹果文档）。

人们会期望，在注册GKLocalPlayerListener之后，在经过身份验证之后，当适当的事件发生时，将调用GKLocalPlayer.localPlayer()中的所有方法。GKLocalPlayerListener

但是，除了调用“player(player: GKPlayer, receivedTurnEventForMatch match: GKTurnBasedMatch, didBecomeActive: Bool)”之外，其他所有方法，包括“player(player: GKPlayer, matchEnded match: GKTurnBasedMatch)”，在此类事件发生时都不会被调用。

我们需要注册其他听众还是我缺少什么？

关于检测您已被邀请参加基于回合的比赛：没有发送任何事件，但是当您从服务器查询您的比赛列表时，您会突然出现一个新的比赛（并且您的状态将被邀请）。（不过，收件人确实会收到 UIAlert 提示他们已收到邀请）

关于各种 API 函数是否/何时触发，我花了很多很多时间试图破译这些各种功能何时触发。我已经针对函数或文档打开了多个错误。这是我目前的笔记；这就是我在帮助程序类中组织所有委托函数的方式，指示它们应用到哪个侦听器以及导致它们触发的原因的注释。

你可以看到有几个我从来没有破译过。对此列表的任何其他输入/说明将不胜感激。

编辑：根据 μ4ρκ05 的反馈更新了“提醒”通知的状态。

好的，您对各种方法的列表和解释让我思考。首先。收到比赛时没有收到通知的问题对我来说是最紧迫的问题之一，因为如果您没有收到通知，则意味着您需要提取数据。那么，您何时再次加载匹配项？每 x 秒或每次带有游戏列表的视图控制器出现？两者都会发出不必要的网络调用，这会很烦人，而且由于游戏列表可能需要重新加载，没有任何实际更改，它可能看起来也不好。所以起初我在考虑使用交换，以便对手可以得到通知并重新加载游戏。然而，读了你的帖子，我想起了player receives a reminder (UNTESTED)那个叫做receivedTurnEventForMatch. 现在，我设法通过初始化新游戏、转弯、然后发送提醒来让对手收到新游戏的通知。

我已经更新了我的TurnBasedSkeleton项目。

我没有足够高的声誉来评论 Thunks 的答案，但我可以提交我自己的，所以这就是我将这些信息发布出去的方式。问题的最大部分是没有关于如何使用此代码的示例，并且缺少文档。因此，代码未触发并不能证明代码已损坏，只是我们不知道如何使用它。

但是根据 Thunk 所做的陈述，我能够得到 player:didModifySavedGame 和 player:hasConflictingSavedGames，他说他从未见过他们开火。

这些是 GKSavedGameListener 疯狂的方法。我对这个协议的问题是它没有一个委托来分配它，所以我可以在我的程序中选择任何类并使其符合这个协议，然后期望这些方法被触发，这似乎不太可能。所以我需要某种代表来说明哪个类符合要求。

我发现通过将 localPlayer.registerListener(self) 设置为 self 是符合标准的类，我可以让它们触发。

因此，请仔细检查任何未使用此 set 触发的方法，并让我们知道它是否工作得更好。

你没有错过任何东西。苹果选择了

删除 [这些] 功能

我向 Apple 提交了一个 bug 以进一步调查。至少可以说，他们的反应并不令人满意。
