An array of
NSStringobjects that contains the player identifiers that the challenge is to be sent to.
The preformatted, player-editable message that is being sent to other players.
A block to be called after the view controller has been displayed. Contains the reason the handler was called and all player identifiers that the challenge was sent to.
UIView view containing the player identifiers and a player-editable message.
The view controller returned is presented modally from the top view controller. After the view controller is displayed and the player sends or cancels the challenge, the completion handler block is called.
When this method is called, it creates a new background task to handle the request. The method then returns control to your game. Later, when the task is complete, GameKit calls your completion handler. The completion handler is always called on the main thread.
