Is there any way to call saveCurrentTurnWithMatchData without sending a push notification?

问题

I have a Game Center game that allows players to make multiple moves per turn. In iOS 6, Apple implemented a great feature in saveCurrentTurnWithMatchData that allows you to do just that- it saves the data to game center to prevent cheating by repeatedly redoing a move for instance, without advancing to the next player.

The problem is, I have discovered that this actually triggers the same Push Notification taht gets sent when the player does end their turn. So other players in the game will see a badge on the app's icon and mistakenly think it's their turn when it isn't.

Has anyone found a workaround for this? Any way to call saveCurrentTurnWithMatchData without sending a push notification? If not, this seems like a design flaw that should probably be brought to Apple's attention.

I agree, this seems like a design flaw. I am also developing a turn-based game whereby a player can take several actions before passing control over to the next player. Meanwhile, I want other players to witness every action while they are looking at the game. If the other players are not running the app, I want them to receive a push notification only when the control is passed to another player.

Instead of using saveCurrentTurnWithMatchData:, I use endTurnWithNextParticipants: but I specify the current player rather than the next. This seems to do the trick:

NSTimeInterval interval = 86400; // seconds in a day
[currentMatch 
  endTurnWithNextParticipants:[[NSArray alloc] initWithObjects:currentMatch.currentParticipant,nil] 
  turnTimeout:interval matchData:[self packMatchData]
  completionHandler:^(NSError *error) {
    if (error) {
       // handle error
    }
  }
];
