How can i manage the timer between different users in turn based game for user's turn ? I want to make user play his turn one by one. Suppose , if there are four players in the game. when player A makes his move, others cannot touch the game board. Like wise when players turn is changed and player B makes his move, others will wait untiil his turn come. But how to maintain if player C doesnot make the move . Should i maintain the timer from the user side. or is there any functionality availble in the server/sdk ?
BTW i am using iOS SDK.
