ios-gamecenter-singleton

Singleton Implementation of Game Center for iOS, for managing Leaderboards, achievements and multi player.

In the instructions below I assume you have an app already configured on the iOS Provisioning Portal and iTunes Connect:

How-to Use

1. Include the files on your project
2. Import GameCenterManager.h in your App Delegate and in all the classes you need to use Leaderboards or Achievements with

   #import "GameCenterManager.h"

3. Authenticate the user on your applicationDidFinishLaunching: or applicationDidFinishLaunchingWithOptions: method by calling

   [[GameCenterManager sharedGameCenterManager] authenticateLocalUser];

Note: If no local user is authenticated, a Game Center login window will appear. 4. Modify your achievements and leaderboards accordingly on GameCenterConstants.h 5. Report an achievement by using:

[[GameCenterManager sharedGameCenterManager] submitAchievement:kAchievement_FlySwatter percentComplete:100.0f];

6. To submit a score to a Leaderboard:

[[GameCenterManager sharedGameCenterManager] submitScore:self.totalBugs forLeaderboard:kLeaderboard_EatenBugs];
