Documentation

GameCenter.authenticatePlayer(success, error)
Displays the Game Center login UI, or automatically log the player in if they've previously authenticated. The success callback is passed an object which looks like the following: { authenticated: true, playerID: XXXXX, alias: "Public display name" }. The error callback is passed a string which gives details about the error.

GameCenter.reportScore(score, category, success, error)
Send a score to a Game Center leaderboard, represented by the category string. category must be the identifier that you set up for the leaderboard in iTunes Connect. The error callback is passed a string which gives details about the error. The plugin doesn't save/resend scores if there was a transmission failure; it's up to you to keep track of which scores were successfully sent. A common technique for this is to save your scores in an array, iterate/send each one, and splice the score out of the array if it was successfully sent.

GameCenter.showLeaderboard(category, time, success, error)
Display the "native" Game Center UI for the category leaderboard. category must be the identifier that you set up for the leaderboard in iTunes Connect. time is a string representing the time interval of displayed scores. Acceptable values are "day," "week," or "all." The error callback is passed a string which gives details about the error.

GameCenter.retrieveScores(category, friends, time, range, success, error)
Get an array of high scores to use in your own custom UI. category must be the identifier that you set up for the leaderboard in iTunes Connect. friends is the string "global" or "friends" to show scores from friends only. time is a string representing the time interval of displayed scores. Acceptable values are "day," "week," or "all." range is the number of returned results, from 1 to 100 (the default is 25). success is passed the array of scores, while error is passed a string which gives details about the error.
