game-center

So I've updated the way I authenticate players for gamecenter and I'm still getting a crash at start up. This is the new way I authenticate: - (void) authenticateLocalPlayer { GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer]; localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){ if (viewController != nil) { NSLog (@"user not logged in to GC"); } else if ([GKLocalPlayer localPlayer].isAuthenticated) { NSLog(@"gamecenter authentication process succeeded"); } else { NSLog(@"user not authenicated"); } }; } Here's what is shown when it crashes: 2014-11-12 16

I have a 100% reproducible crash here. Crash if backgrounding cocos2d 2.1 app in iOS7 while watching Game Center screens (leaderboard, achievement). It crashes instantly when pushing the home button. Crash on line 275 in CCGLView.m: if(![_context presentRenderbuffer:GL_RENDERBUFFER]) The itching thing is, I downloaded a fresh copy of official cocos2diphone 2.1 the other second, installed its templates and ran the staple application after hooking it up to the same app id as my problematic app that already have game center leaderboards etc set up. It does not crash. So I ran a diff on the

Trying to figure out best way to work with Achievements in Game Center in case of offline mode (e.g. Airplane mode turned on). As far as I understand Game Center in iOS 5+ takes care of offline submitted achievements and scores. It acts like a proxy cache and submits them to online Game Center next time user is online. Considering this here is what I do: At the user authentication success I load achievments and store them in a dictionary. [GKAchievement loadAchievementsWithCompletionHandler:^(NSArray *gcAchievments, NSError *error) { if (error) { ..skipped ..} //This dictionary will store

This is a new compiler warning that only showed up when I updated XCode to 4.6. My code is lifted directly from Apple's documentation (this is my iOS 6 code btw). GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer]; localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error) { [self setLastError:error]; if(localPlayer.authenticated){ Warning--Capturing 'localPlayer' strongly in this block is likely to lead to a retain cycle The issue is that the localPlayer object is keeping a strong reference to itself - when localPlayer is "captured" for use within the

I'm trying to implement a gamecenter aware app targeted to iOS 6. To give some info on the environment I'm working on mac os 10.7.5 with XCode version is 4.5.2 and xcode is running iphone and ipad simulator version 6.0. The problem is I cannot connect to gamecenter in sandbox mode neither through ipad or iphone simulator, but the same code works as desired while testing in my iphone. I followed the gamecenter programming guide in apple's developer library and I got this atm it is called from applicationDidFInishLaunching in appdelegate: - (void)authenticateLocalUser:(UIViewController *

I was trying to implement an event listener in a turn based game so a player can receive when his turn is active or when he is invited by a friend. GKTurnBasedEventHandler is deprecated in IOS 7 and i read in the documentation that i should use GKLocalPlayerListener; but that's the extend of it. Is there someone who used it already, because there is no info anywhere. This is what i tried before, and it does not work. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
