Anyone knows what I need to do to have both my free and paid versions feed the same Game Center leader board?
回答1:
I'm afraid that's not possible, because the Game Center uses the application's "bundle identifier" (such as com.myCompany.myCoolGame) to identify a game -- and two apps cannot have the same identifier.
That's at least the status in iOS 4.1.
回答2:
Provide a complete app, but disable features. Then use an in-app purchase to unlock these functionality. This way, 'both' Apps will have the same identifier.
回答3:
Starting from iOS 6.0 there is a functionality called Game Center Groups. You can set these groups in iTunes Connect and assign multiple applications to them. This way they can share leaderboards and achievements.
