context property is stored and returned to your game, but is otherwise ignored by Game Center. It allows your game to associate an arbitrary 64-bit unsigned integer value with the score data reported to Game Center. You decide how this integer value is interpreted by your game. For example, you might use the
context property to store flags that provide game-specific details about a player’s score, or you might use the context as a key to other data stored on the device or on your own server. The context is most useful when your game displays a custom leaderboard user interface.
