游戏中心是否有可以脱机使用的缓存机制?游戏中心是否有可能在离线模式下收集分数,当网络状态更改为在线时,它会将分数传递给服务器?是否可以在离线模式下阅读下载的分数?
如果上述问题的答案为否,是否有可以为我们执行此操作的库?
感谢您的帮助。

Axeva的答案不正确 - GKLocalPlayer没有定义“resubmitStoredScores”这样的方法。相反,此方法是在Apple的iOS开发人员库中提供的example code中定义和实现的,该库演示了GameKit排行榜的使用。
如果您不想从Apple的示例中复制代码,那么有一些库。一些谷歌搜索在github.com上发现以下点击:
如果这些都不能满足您的需求,您需要实施自己的解决方案。

是的,Game Center会缓存分数。您可以在应用委托的didFinishLaunchingWithOptions中调用GKLocalPlayer对象的resubmitStoredScores方法。
以下是一个例子:
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
if (localPlayer.isAuthenticated) {
// Enable Game Center Functionality
self.gameCenterAuthenticationComplete = YES;
if (! self.currentPlayerID || ! [self.currentPlayerID isEqualToString: localPlayer.playerID]) {
[[NSUserDefaults standardUserDefaults] setBool: NO forKey: kGameInProgress];
// Switching Users
if (!self.player || ![self.currentPlayerID isEqualToString: localPlayer.playerID]) {
// If there is an existing player, replace the existing PlayerModel object with a
// new object, and use it to load the new player's saved achievements.
// It is not necessary for the previous PlayerModel object to writes its data first;
// It automatically saves the changes whenever its list of stored
// achievements changes.
self.player = [[[PlayerModel alloc] init] autorelease];
}
[[self player] loadStoredScores];
[[self player] resubmitStoredScores];
}
} else {
// User has logged out of Game Center or can not login to Game Center, your app should run
// without GameCenter support or user interface.
self.gameCenterAuthenticationComplete = NO;
}
}];
