GKBase is the top level implementation for the different player objects. From
GKBase, player objects follow two different paths.
GKCloud objects use the player's iCloud account to join games, invite other players, save data, and send information between players.
GKPlayer objects are used by the GameKit legacy classes to identify a Game Center account. In either case, accessing achievements, leaderboards, and challenges requires authentication of the local player. Use
GKLocal to ensure the current player has a Game Center account and is logged in.
