Improves integrity of game rankings
Apple has updated Game Center in order to cope with cheaters, according to a notice issued to developers. "You can now view and manage the top 100 scores and usernames for all of your Game Center leaderboards," the company writes. "Protect your legitimate players by signing in to iTunes Connect to delete fake scores or block players that post fake scores. You can also restore scores and players within the same time period," the memo continues.
When iOS 7 was introduced, Apple quietly supplied developers with some initial tools to fix leaderboards, including score caps and the ability to reject unsigned score submissions. These and the more recent changes should help improve the credibility of Game Center, which is used by a number of apps but has not proven as popular with gamers as Apple initially wanted. Aside from leaderboards, the service also offers elements like challenges and matchmaking.
