My GKMatch has no players...?

- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match
{
    self.myMatch = match;
    NSLog(@"%d",[[self.myMatch playerIDs]count]);

}

But my console returns 0. Shouldn't it return 2 instead?

Could it be that you are not actually connecting them?

Are you in fact using GKMatchmaker and GKMatchmakerViewController?

In your testing, you are sure you are using TWO DIFFERENT game center accounts?

I'm afraid I'm not familiar with the game center system.

GKMatchmaker returns you a match before connections have been established between players; at this stage, all the players are in the process of connecting to each other.

The playerIDs property is initially set to the number of players already connected to the match; the array may be empty. Whenever a player is connected to the match, that player’s player identifier is added to the array.

Additionally, some players can fail to connect (I haven't tested this case so I don't know if you get an error returned)

What you're looking for is GKMatch.expectedPlayerCount

The value of this property is decremented whenever a player connects to the match. When its value reaches zero, all expected players are connected, and your game can begin the match.

I also suspect that GKMatch.playerIDs does not include the player; i.e. you'll probably see expectedPlayerCount = 1 immediately after connecting.

I'm not sure what GameKit does about threads.
