“This game is not recognized by Game Center” error

阅读更多关于 “This game is not recognized by Game Center” error

问题 I'm struggling to get past the first stage of getting Game Center integration to work. I've got this far: I've created a new, clean app, added the GameKit headers and the basic authenticateWithCompletionHandler: method in the app delegate. Starting the app in the simulator brings up the login dialogue. If I create a NEW account via the login dialogue, then that user gets authenticated and the app loads successfully. If I attempt to log in with that account a second time, OR use an account

问题 trying to implement a multiplayer. Using the sample from Game Center - Sending and receiving data. Everything seems okay, but in apple documentation there is also said about invitation handler. [GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) { // Insert application-specific code here to clean up any games in progress. if (acceptedInvite) { GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite

问题 I'm implementing a turn-based game with multiplayer mode through gamecenter. I have 2 devices (1 ipad, 1 iphone) to test in sandbox mode which were working fine but lately it has started to struggle in auto matchmaking process. After I send the first turn from one user, the other device doesn't immediately recognize that game but opens up its own fresh game. Before it was able to immediately spot the game started in the other device and matchmaking was fairly straightforward. And I don't

iOS Game Kit Turn Based Match Programatic Rematch

问题 I have a 2-player, iOS turn-based game that uses the game center and GKTurnbasedMatch. Is there a way to programmatically rematch an opponent after a match has finished? I would like to give the players one-button access to starting a new match with each other. If there is not a one button approach, what are some potential alternatives? 回答1: Indeed it appears a full programmatic solution is being ignored by Game Center. A pain, no doubt. Try the following in your @selector(doRematchTap)... or

Any way to programmatically reset leaderboards?

阅读更多关于 Any way to programmatically reset leaderboards?

问题 As I look into documentation of GKScore and GKLeaderboard, there is no way to reset scores reported by player to particular leaderboard in GameCenter. Am I right? This seems quite inconsistent, since it is possible to reset achievements: [GKAchievement resetAchievementsWithCompletionHandler:^(NSError *error) { ... }]; Any thoughts? 回答1: You are correct. There is no way to reset a Game Center leaderboard category or to remove a category once it's been launched in a live app. Apple did allow a

问题 I keep getting this crash report from GA and users... However i cannot reproduce this exception by testing iphone5,5s,6 with both ios7 and ios8. This issue comes nowhere when application did enter to background. The strange part is that gamecenter will call spritekit, for showing achievement banner? Does anyone has the same issue?

I give up on that point, I just can't figure out what is wrong and where... Here is the problem: in my iPhone application using Cocos2d, I configured autorotation through a viewController; however, since, when Game center opens its view as the user taps on "Create new account" during the authentication, this view does not receive any touch, but the touch go to the game's view (which is hidden under the Game center view). I have tried everything I thought about, but since I did not find any callback about this Game Center View, it is hard to find a way to correct this... Here is the
