Has anybody gotten game center working with iOS 7? I can get it to compile, but the pop-up screen never appears anymore when the app launches. It's pretty crazy how Apple never thinks to update their sample code. The GKTapper sample is the same one from 4 years ago and I has all kinds of errors now that BT 3.0 is using arc

I think this is the book i used to set up game center in the NAD advanced quiz plugin. I havn't tested it with ios 7 yet. But I found gamecenter really simple to set up. Its in the last chapter about gamekit. http://www.amazon.com/iOS-Recipes-Problem-Solution-Hans-Eric-Gr%C3%B6nlund/dp/1430245999/

thanks guys - I finally managed to find a stack overflow post that solved it for me. I linked to the working iOS 7 code in this thread - http://www.buzztouch.com/forum/thread.php?fid=6F54B0D255A4AF70998EBDF&tid=6F54B0D255A4AF70998EBDF

I can't seem to get my gamecenter to load. no errors, but not sure if i've added it correctly to the view controller. i noticed that there were two viewdidload methods so i added the gamecenter code to that block of code however, the gamecenter doesnt popup anymore when the app is launched nor does it show up in the gamecenter game list here is my code, @absentia can you match it up with your code, just in case there is a difference? Thanks! //viewDidLoad... -(void)viewDidLoad{ [BT_debugger showIt:self theMessage:@"viewDidLoad (super)"]; [super viewDidLoad]; self.currentLeaderBoard = kLeaderboardID; self.currentScore = 0; if ([GameCenterManager isGameCenterAvailable]) { [self.gameCenterManager setDelegate:self]; [self.gameCenterManager authenticateLocalUser]; } else { // The current device does not support Game Center. } //adjust view edges on iOS7, depending on the navBar transparency... if([self respondsToSelector:@selector(edgesForExtendedLayout)]){ if(![[BT_strings getStyleValueForScreen:self.screenData nameOfProperty:@"navBarStyle" defaultValue:@""] isEqualToString:@"transparent"]){ self.edgesForExtendedLayout = UIRectEdgeNone; } } } - (IBAction) showLeaderboard { GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; if (leaderboardController != NULL) { leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self; [self presentViewController: leaderboardController animated: YES completion:nil]; } } - (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController { [self dismissViewControllerAnimated: YES completion:nil]; } - (IBAction) showAchievements { GKAchievementViewController *achievements = [[GKAchievementViewController alloc] init]; if (achievements != NULL) { achievements.achievementDelegate = self; [self presentViewController: achievements animated: YES completion: nil]; } } - (void)achievementViewControllerDidFinish:(GKAchievementViewController *)viewController; { [self dismissViewControllerAnimated: YES completion:nil]; } //GameCenter View Did Unload - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; self.gameCenterManager = nil; self.currentLeaderBoard = nil; self.currentScoreLabel = nil; }

The code I use is slightly different..I call authenticateLocalUser in viewController.m with after a three second delay. Otherwise it seems to load behind the view. Try replacing all of your code with this - //GameCenter View Did Load - (void)viewDidLoad { [super viewDidLoad]; //adjust view edges on iOS7, depending on the navBar transparency... if([self respondsToSelector:@selector(edgesForExtendedLayout)]){ if(![[BT_strings getStyleValueForScreen:self.screenData nameOfProperty:@"navBarStyle" defaultValue:@""] isEqualToString:@"transparent"]){ self.edgesForExtendedLayout = UIRectEdgeNone; } } self.currentScore = 0; if ([GameCenterManager isGameCenterAvailable]) { self.gameCenterManager = [[GameCenterManager alloc] init]; [self.gameCenterManager setDelegate:self]; [self performSelector:@selector(authenticateLocalUser) withObject:nil afterDelay:3]; } else { // The current device does not support Game Center. } } - (IBAction) showLeaderboard { GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; if (leaderboardController != NULL) { leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self; [self presentViewController: leaderboardController animated: YES completion:Nil]; } } - (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController { [self dismissViewControllerAnimated: YES completion:nil]; } - (IBAction) showAchievements { GKAchievementViewController *achievements = [[GKAchievementViewController alloc] init]; if (achievements != NULL) { achievements.achievementDelegate = self; [self presentViewController: achievements animated: YES completion:Nil]; } } - (void)achievementViewControllerDidFinish:(GKAchievementViewController *)viewController; { [self dismissViewControllerAnimated: YES completion:nil]; } -(void)authenticateLocalUser { __weak GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer]; localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error) { if(viewController) { [[[UIApplication sharedApplication] keyWindow].rootViewController presentViewController:viewController animated:YES completion:nil]; } else if(localPlayer.isAuthenticated == YES) { NSLog(@"already authenticated"); } else { NSLog(@"game center disabled"); } }; }

ah ok. great thanks. i did notice later that the code worked but it didn't load. your code worked beautifully! Thanks
