我想使用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iPhone上尝试时,会收到如下所示的错误代码.我无法理解这一点.我无法控制在哪里可以保存游戏数据,所以为什么系统试图在没有权限的情况下保存它？

解决方法
我改变了SaveGame的名字,错误消失了.
