I'm trying to implement a real-time multiplayer game with a custom UI (no GKMatchMakerViewController). I'm using startBrowsingForNearbyPlayersWithReachableHandler:
^(NSString *playerID, BOOL reachable) to find a local player, and then initiating a match request with the GKMatchmaker singleton (which I have already initiated).
Here's where I'm having trouble. When I send a request, the completion handler fires almost immediately, without an error, and the match it returns has an expected player count of zero. Meanwhile, the other player definitely has not responded to the request.
Relevant code:
- (void) findMatch
{
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = NUM_PLAYERS_PER_MATCH; //2
request.maxPlayers = NUM_PLAYERS_PER_MATCH; //2
if (nil != self.playersToInvite)
{
// we always successfully get in this if-statement
request.playersToInvite = self.playersToInvite;
request.inviteeResponseHandler = ^(NSString *playerID, GKInviteeResponse
response)
{
[self.delegate updateUIForPlayer: playerID accepted: (response ==
GKInviteeResponseAccepted)];
};
}
request.inviteMessage = @"Let's Play!";
[self.matchmaker findMatchForRequest:request
withCompletionHandler:^(GKMatch *match, NSError *error) {
if (error) {
// Print the error
NSLog(@"%@", error.localizedDescription);
}
else if (match != nil)
{
self.currentMatch = match;
self.currentMatch.delegate = self;
// All players are connected
if (match.expectedPlayerCount == 0)
{
// start match
[self startMatch];
}
[self stopLookingForPlayers];
}
}];
}
