I am creating an application that supports a game center. There is a facebook button on the leaderboard page. However, it is disabled. Will it be turned on when it is sold in the Appstore, or do I need to make additional configurations in the code?
Yes, this will be included in the production version of the application only if the user has installed and enabled integration with Facebook in iOS 6. Otherwise, he will say that Facebook Liking is not available.
