问题
I want to create a leaderboard in Game Center for the best scores submitted today, and I want it reset every day at midnight.
It's not hard to just create a "most recent score" leaderboard and keep track of the score for the day in the app and submit it, however my concern is that users who do not launch the app the next day will have an old score which remains in the "best score today" board until they launch it.
Is there any way to make scores expire, or only show the current scores for the day in a Game Center leaderboard?
