GKLocalPlayer和saveGameData的问题

Question

我想用GKLocalPlayer和saveGameData方法保存游戏数据.

[localPlayer saveGameData:playerData withName:@"SolarFlares" completionHandler:^(GKSavedGame *savedGame, NSError *error) {
    if (savedGame != nil) {
        NSLog(@"Player data saved to GameCenter");
    }else{
        NSLog(@"Player=%@ data NOT saved to GameCenter, error=%@", localPlayer, error.description);
    }
}];

上面的代码在xcode模拟器上工作正常,但是当我在我的iPhone上尝试它时,我得到如下所示的错误代码.我无法弄清楚这一点.我无法控制它保存游戏数据的位置,那么为什么系统会尝试将其保存在没有权限的地方!？!
