Objective c （GKMatch GKVoiceChat）-在调用didFindMatch后，两名玩家都会断开连接

我正在尝试使用GKMatch对象在两个连接的玩家之间实现语音聊天。 我的玩家经过身份验证，我还可以使用GKMatchmakerViewController创建比赛

问题是，当我通过代理回调

matchmakerViewController:didFindMatch:

接收到GKMatch对象时，我设置了AudioSession和VoiceChat对象。但是在这个方法返回后不久，我在GKMatch的委托

match:player:didChangeState:

以下是我如何在didFindMatch回调中创建AudioSession和VoiceChat：

- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match {

    [viewController dismissViewControllerAnimated:YES completion:nil];

    self.match = match;
    match.delegate = self;

    if (!_matchStarted && match.expectedPlayerCount == 0)
    {
        NSError *err = nil;
        AVAudioSession *audioSession = [AVAudioSession sharedInstance];
        [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&err];
        [audioSession setActive: YES error:&err];

        if (err)
        {
            NSLog(@"%@",err.localizedDescription);
        }
        self.teamChannel = [[match voiceChatWithName:@"redTeam"] retain];

        _teamChannel.volume = 1.0f;
        _teamChannel.active = YES;

        [_teamChannel start];

        _teamChannel.playerStateUpdateHandler = ^(NSString *playerID, GKVoiceChatPlayerState state) {
            switch (state)
            {
                case GKVoiceChatPlayerSpeaking:
                    NSLog(@"Speaking...");
                    break;
                case GKVoiceChatPlayerSilent:
                    break;
                    case GKVoiceChatPlayerConnected:
                    NSLog(@"Connected.");
                    break;
                    case GKVoiceChatPlayerConnecting:
                    NSLog(@"Connecting..");
                    break;
                    case GKVoiceChatPlayerDisconnected:
                    NSLog(@"Disconnected.");
                    break;
            }
        };
    }
}

我从来没有在playerStateUpdateHandler中接到过电话。我在以下函数中收到断开连接的呼叫： `-（void）match:（GKMatch*）match player:（NSString*）playerID didChangeState:（GKPlayerConnectionState）state{ 如果（_match！=match）返回

}`

问题：-

我听不到任何一端的声音，我是不是遗漏了什么？ 我已经试了三天了，而且（作为一个附带问题）我不确定我的第二个球员该怎么办。例如，当有匹配时，我在其中一台设备上得到didFindMatch，而在另一台设备上没有回拨。我需要在其他设备上发送消息吗？比赛怎么样

非常感谢您的快速帮助。

如果仅在托管设备上调用了

didFindMatch

，则听起来您是在邀请玩家而不是自动匹配玩家。客户机在inviteHandler中发现了这一点

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) 
{
    if (acceptedInvite)
    {
        GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite];
        mmvc.matchmakerDelegate = self;

        // Do client connection stuff here
    }
    else if (playersToInvite)
    {
        GKMatchRequest *request = [[GKMatchRequest alloc] init];
        request.minPlayers = 2;
        request.maxPlayers = 2;
        request.playersToInvite = playersToInvite;

        GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithMatchRequest:request];
        mmvc.matchmakerDelegate = self;

        [pViewController presentViewController:mmvc animated:YES completion:nil];
    }
};

如果您正在自动匹配游戏，两名玩家都将在

[[GKMatchmaker sharedMatchmaker]findMatchForRequest:RequestWithCompletionHandler:^（GKMatch*match，NSError*error）

如果仅在托管设备上调用了

didFindMatch

，则听起来您是在邀请一个播放机，而不是自动匹配一个播放机。客户端会在InvitedHandler中发现这一点

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) 
{
    if (acceptedInvite)
    {
        GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite];
        mmvc.matchmakerDelegate = self;

        // Do client connection stuff here
    }
    else if (playersToInvite)
    {
        GKMatchRequest *request = [[GKMatchRequest alloc] init];
        request.minPlayers = 2;
        request.maxPlayers = 2;
        request.playersToInvite = playersToInvite;

        GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithMatchRequest:request];
        mmvc.matchmakerDelegate = self;

        [pViewController presentViewController:mmvc animated:YES completion:nil];
    }
};

如果您正在自动匹配游戏，两名玩家都将在

[[GKMatchmaker sharedMatchmaker]findMatchForRequest:RequestWithCompletionHandler:^（GKMatch*match，NSError*error）

 [[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error) 
{
    if (error != nil)
    {
        NSLog(@"MULTIPLAYER MATCH REQUEST FAILED: %@", error.localizedDescription);
    }
    else if (match != nil)
    {
        self.m_pMatchObject = [match retain];
    }
}];
