我正在通过游戏中心实现具有多人模式的回合制游戏。我有 2 台设备（1 台 ipad，1 台 iphone）在沙盒模式下进行测试，它们运行良好，但最近它开始在自动匹配过程中遇到困难。在我从一个用户发送第一回合后，另一台设备不会立即识别该游戏，而是打开自己的新游戏。在它能够立即发现游戏在另一台设备上开始之前，匹配相当简单。而且我不记得更改任何与匹配相关的部分（NSCoding、、GKTurnBasedEventHandler委托GKTurnBasedMatchmakerViewControllerDelegate方法等）。
现在我从一个设备发送第一个回合，需要等待大约 1 分钟，以便其他设备可以成功连接到该游戏。连接发生后 endTurnWithMatchData 调用没有任何问题，它可以在 1-2 秒内发送和接收数据。但是，如果用户开始一个新游戏并且必须等待 1 分钟以便另一个用户可以连接到他的游戏，这将不是一个好的用户体验。有没有人在自动匹配过程中遇到过明显的滞后？我还没有实施邀请，所以我无法检查它。我用 NSKeyedArchiver 存档的比赛数据看起来很大，3396 字节，即使对于几乎没有数据的新游戏也是如此。这是我的代码的相关部分：
