When should it init GameCenterManager?

[caoer]

I first try to call

[[GameCenterManager sharedManager] setupManager];
[[GameCenterManager sharedManager] setDelegate:self];

when the app launches. However, the result comes from [self checkGameCenterAvailability] is not correct. Because of the asyn call in localPlayer.authenticateHandler.
I think this will make following code in init method not really useful. Because if GameCenterManager is init when app starts, gameCenterAvailable will always be NO. The essential syncGameCenter call is not called.

        if (gameCenterAvailable) {
            // Set GameCenter as available
            [self setIsGameCenterAvailable:YES];

            if (![[NSUserDefaults standardUserDefaults] boolForKey:[@"scoresSynced" stringByAppendingString:[self localPlayerId]]]
                || ![[NSUserDefaults standardUserDefaults] boolForKey:[@"achievementsSynced" stringByAppendingString:[self localPlayerId]]])
                [self syncGameCenter];
            else
                [self reportSavedScoresAndAchievements];
        }

I've put a temporary fix as following, everything works fine.

        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [[GameCenterManager sharedManager] setupManager];
            [[GameCenterManager sharedManager] setDelegate:self];
        });

I think checkGameCenterAvailability might be refactor to use completionHandler ?

Hello,

I've the same issue with latest commit gameCenterAvailable will always be NO and I always see in a log: "scoresSynced not setup" and "achievementsSynced not setup". Why is that? However, after a second I see standard GC banner and afterward method: [[GameCenterManager sharedManager] saveAndReportScore:
works well and my scores sent to GC.
