我的游戏在iOS 10之前运行良好。现在，iOS 10的每个人都无法邀请和玩他们想要的人。
当用户说他们想玩多人游戏时，我会像这样创建一个@echo off
setlocal EnableExtensions DisableDelayedExpansion

GKMatchRequest我使用GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 4;
request.defaultNumberOfPlayers = 2;
来处理邀请等。用户看到一个界面，可以让他们更改比赛中的玩家数量并邀请玩家。让我们说他们只想要2名球员，所以他们离开了，他们想和他们的朋友一起玩。因此，他们使用界面向他们的朋友发送邀请。结果是GKTurnBasedMatchmakerViewController在我的委托上被调用，didFindMatch有4个参与者。它应该只有2个！第一个参与者是本地玩家，另外3个具有状态＆＃34;匹配＆＃34;。所以，他们的朋友甚至不在名单中。有没有人有任何解决这个问题的建议？这个相同的代码在iOS 10之前的iOS版本中运行良好。
答案 0 :(得分：0)
看来，对于IOS10，defaultNumberOfPlayers并没有被尊重。
请注意，GKTurnBasedMatch在给定的匹配中有三种类型的玩家：
如果您查看比赛中所有4名球员的球员状态（使用您的示例），我怀疑您会看到以下结果
如果是这样，那表示忽略了defaultNumberOfPlayers，并且最多创建了4个玩家（1个发起者，1个被邀请者和2个自动匹配插槽）。
解决方法似乎是在创建匹配时将maxNumberOfPlayers设置为所需的上限，在本例中为2。
