Question

I’m using the Standard Matchmaking User Interface and two iPads iOS6. The problem is when I create a new match in the first device, the second device supposed to see the existing match when I view the Matchmaking User Interface but it’s not. I’m sure my code is correct. here is the method:

-(void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers viewController:(UIViewController*)viewController {

    // the view that will present Matchmaker View Controller
    self.viewCaller = viewController;

    GKMatchRequest *request = [[GKMatchRequest alloc] init];
    request.minPlayers = minPlayers;
    request.maxPlayers = maxPlayers;

    GKTurnBasedMatchmakerViewController *viewMatchmaker = [[GKTurnBasedMatchmakerViewController alloc] initWithMatchRequest:request];
    viewMatchmaker.turnBasedMatchmakerDelegate = self;
    viewMatchmaker.showExistingMatches = YES;
    [self.viewCaller presentViewController:viewMatchmaker animated:YES completion:nil];
}

I even tried on two different sample games but the same problem, so how can I solve this ?

Answer 1

When Gamekit does matchmaker for a turnbase match it is trying to find a match with an open slot to fill the player in. If it cannot find an open slot to fill the player in it then creates a new match.

Try on one device to create a match and go through one turn with that device, that is when you call…

 endTurnWithNextParticipants:turnTimeout:matchData:completionHandler:

Then on the other device try looking for a match.
