Chat between players in Game Center turn based match

Question

I am trying to create a turn based game using Game Center. I wanted to know if it is possible to allow the players in the match to chat between each other (either voice or text).

I have looked into it a little and seems that it is possible via the normal game but not a turn based one.

If it is not possible what are the solution or ways to allow this type chat?

Answer 1

Yes, you can have text chat the following way: Without ending the turn, update the matchData object on the GKTurnBasedMatch. The updated NSData will be provided to all players that open your app and are participants in the game. So, your matchData object would have to carry both the game state and the chat state. Unfortunately, I do not see how one could trigger user notifications or badge the app for new chats without having to end the player's turn each time.
