分享同一游戏中心排行榜iOS / tvOS / OS X？

Question

I'm wondering if it is at all possible to somehow share the leaderboard / achievements from say an iOS game center leaderboard, to be used as well for say tvOS and OS X versions of the same game?

Or does each seperate platform have to maintain their own clone of the same leaderboard / achievements?

If this is possible any links to reference material would be awesome, I can't find anything bar the mention of something like this being possible in the tvOS Keynote.

Answer 1

There are two solutions: One for iOS / tvOS, and one for all three.

According to amandavoss from Apple

For iOS and TVOS you can use the new "universal bundle ID" feature where you can add a TVOS version of the app to the existing iOS bundle ID. In iTunes Connect you would just go to the iOS app in question and in the App Store view click + Version. Select TVOS and go from there.

Another option would be to group them games. This would add "grp." to all leaderboard and achievement identifiers but can be shared by all apps in the group (where each app has a unique bundle ID). For that simple "Move to Group" in iTunes Connect.

Answer 2

For iOS and TVOS this is possible, if they use the same BundleID.

If you have an existing iOS project just open iTunes Connect. Hit the '+' button to add an Apple TV version. Both will share their leaderboards.
