This weekend I was working on a game I am developing.
On Level 2 a number of players will get the best score (9 moves). Rather than placing everyone with the same score in 1st position, the first player to get 9 moves is positioned 1st, the second player to get 9 moves is positioned 2nd and so on. Is it possible to make them all tied in 1st place since they all have the same best score?
I can't find anything in Apple's documentation that specifically defines behavior for tie scores, but I think that's the expected behavior. What you'll have to do is retrieve the leaderboard and design your own UI for displaying it.
