iOS GameKit Leaderboard - Get the localplayer's score +/- 50 players around him

I'm programmatically pulling down leaderboard data from g开发者_JS百科ame center and I'd like to limit my data query to the local player's score and the 25 scores above and below him. Is this possible. Is there a way to get the local player's current position in the leaderboard?

Once you make a call to [GKLeaderboard loadScoresWithCompletionHandler:] you can use [[GKLeaderboard localPlayerScore] rank] to get the rank of the current user.

So the next time you call loadScoresWithCompletionHandler, set the range around that value like leaderboardRequest.range=NSMakeRange(localPlayerRank-25, 50)

Also make sure you're not querying for a rank less than one!
