I'm writing the multiplayer part of a turn based game,i'm using game center to manage the matches. Starting a new game with GKTurnBasedMatch do not send immediatly the invite notification to the other player. To send the notification i have to made my move and end first turn... Can i modify this behaviour? I wanna made my first turn only if the other player has already accept my invitation.
You can check the status property of the other participant who is of class GKTurnBasedParticipant. If its status continues to be GKTurnBasedParticipantStatusInvited, forbid yourself from opening the game controller and display an alert.
