Unfortunately you cant use GameCenter directly with Corona yet.

Which dolphin game btw? Dolphins Tale doesn’t support GameCenter. [import]uid: 8600 topic_id: 15276 reply_id: 56389[/import]

what i mean is to show the gamecenter like dolphin. i know using game center in corona by use the openfeint.
i only know to show the gamecenter, but how can i show leaderboard and achievements like in Dolphin game, not using directly for add score. [import]uid: 7427 topic_id: 15276 reply_id: 56390[/import]
