如果您取消游戏中心登录次数足够多，操作系统将禁用该游戏的游戏中心.在 iOS7 之前，您可以使用游戏中心应用程序再次手动登录，当您再次启动游戏时，它会登录.

If you've cancelled game center sign in enough times, the OS disables game center for that game. Prior to iOS7, you could manually sign in again using the game center app, and when you launch your game again it would sign in.

然而，在 iOS7 中，当操作系统为您的游戏禁用游戏中心时，它似乎完全被禁用.我发现使用设置">通用">重置">重置所有设置"将恢复以这种方式禁用的游戏的游戏中心功能.

However, in iOS7, it appears that when the OS disables game center for your game, it's completely disabled. I've found that using Settings > General > Reset > Reset All Settings will restore game center functionality for games that have been disabled in this manner.
