game-center

问题 I'm working on integrating turn based matches in my game and a few days ago I started getting weird errors from the GameKit API saying that the local player is not authenticated, even though he is. When I launch the app, the authenticateHandler is called, the view controller is displayed and after entering the password, the authenticaHandler is called again and the local player seems to be authenticated. isAuthenticated returns YES . But as soon as I start using any of the GameKit APIs like

问题 When I go to update my app, will the old leaderboards that I created in previous versions stay the same in future updates for my app or will I have to create new leaderboards to follow with every update? 回答1: They'd stay the same unless you did anything explicitly. Just don't do anything and push the update. 来源： https://stackoverflow.com/questions/26939057/game-center-app-update-leaderboards-stay-the-same

问题 Right now I am trying to make a leaderboard I created show up. The player is authenticated just fine, but when the game center window opens it is very strange. Here is a picture: Here is the code I am using to display this image: override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { self.showLeaderboard() } func showLeaderboard() { var leaderView = UIViewController() var leaderViewController = GKGameCenterViewController(rootViewController: leaderView) leaderViewController

问题 I've been searching for a definitive answer on this, but I get some inconsistent answers. Apple docs state 64k bytes. However, online I find multiple sources that say 4k bytes is the max. Is this a difference between iOS 5 and iOS 6? 回答1: It was 4KB, now its 64KB.

Not 100% sure, though. 回答3: There is a read only

问题 I have an iOS application that I'm just starting to implement game center support for. I call the authenticateWithCompletionHandler method during loadView for my main (root) view controller.

问题 Using the sandboxed Gamecenter. No matter what I do the scores never appear in a leaderboard. I am using the following code: - (void)scoreReported: (NSError*) error { NSLog(@"%@",[error localizedDescription]); } - (void)submitScore{ if(self.currentScore > 0) { NSLog(@"Score: %lli submitted to leaderboard %@", self.currentScore, self.currentLeaderBoard); [gameCenterManager reportScore: self.currentScore forCategory: self.currentLeaderBoard]; } } And scoreReported doesnt produce an error, yet

问题 So today i started developing with the new iOS 6 SDK and noticed that my game has a new Facebook Like button in Game Center(which is greyed out because i didn't specify anything on it yet). So my question is, how can i put a link of a facebook page behind that "Like" button? My iPhone game has a facebook page already btw. Thanks already, 回答1: Hope it is not too late. Just watched one of WWDC videos and they said, if someone will click the like button, it'll means that person like the game and
