Question

我对gamecentre一无所知。我正在研究COCO应用程序我已经完成gamecenter guide并能够将游戏中心集成到我的应用程序中。

1） 现在，我可以通过我的应用程序在游戏中心输入分数。 通过这样做： -

- (void) reportScore: (int64_t) score forCategory: (NSString*) category 
{
    GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:category] autorelease]; 
    scoreReporter.value = score;
    [scoreReporter reportScoreWithCompletionHandler: ^(NSError *error) 
     {
         [self callDelegateOnMainThread: @selector(scoreReported:) withArg: NULL error: error];
     }];
}

我昨天工作正常。但是现在如果我试图更新分数它没有更新。请任何人知道游戏中心没有更新分数的原因我试图搜索但没有得到任何东西。

2）我想发送当前纬度＆amp;一个玩家到另一个玩家的经度。我开始知道GKMATCH可以

GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
    request.minPlayers = 1;
    request.maxPlayers = 1;

    [[GKMatchmaker sharedMatchmaker] findMatchForRequest:request
                                   withCompletionHandler:^(GKMatch *match, NSError *error) {
                                       if (error || !match) {
                                           // handle the error
                                       }
                                       else if (match != nil){
                                           // match found
                                       }}];

    /*GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
    request.minPlayers = 1;
    request.maxPlayers = 1;
    GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithMatchRequest:request];
    mmvc.matchmakerDelegate = self;
    currentMatch.delegate=self;
    [self presentModalViewController:mmvc animated:YES];*/
    //[mmvc release];
}
- (void)match:(GKMatch *)match player:(NSString *)playerID didChangeState:(GKPlayerConnectionState)state {
    switch (state){
        case GKPlayerStateConnected: 
            if (match.expectedPlayerCount == 0) {
                // start the match
            }
            break;
        case GKPlayerStateDisconnected:
            // remove the player from the match, notify other players, etc
            break;
    } 
}
- (void)matchmakerViewControllerWasCancelled:(GKMatchmakerViewController *)viewController{}

// Matchmaking has failed with an error
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFailWithError:(NSError *)error{
}


// A peer-to-peer match has been found, the game should start
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match{
}

// Players have been found for a server-hosted game, the game should start
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindPlayers:(NSArray *)playerIDs{
}

// An invited player has accepted a hosted invite.  Apps should connect through the hosting server and then update the player's connected state (using setConnected:forHostedPlayer:)
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didReceiveAcceptFromHostedPlayer:(NSString *)playerID {
}
- (void) sendPosition
{
    NSError *error;
    NSString* str = @"teststring";
    NSData* data = [str dataUsingEncoding:NSUTF8StringEncoding];
    //  NSData *packet = [NSData dataWithBytes:&msg length:sizeof(PositionPacket)];
    [currentMatch sendDataToAllPlayers: data withDataMode: GKMatchSendDataUnreliable error:&error];
    if (error != nil)
    {
        // Handle the erro.r
    }
}

但是我不知道为什么但没有调用GKMatchmakerViewController的委托方法我设置了委托但仍然甚至我无法获得GKMATCH（这里是currentMatch）。所以由于这个原因 [currentMatch sendDataToAllPlayers：data withDataMode：GKMatchSendDataUnreliable error：＆amp; error]; 这种方法不起作用。

因为CurrentMatch参考是0X0。请帮帮我。如何发送和回收数据。我做错了什么？或者还有别的事要做。

请帮帮我。

谢谢
