我正在尝试在我为 iOS 开发的游戏上设置语音聊天，它成功地创建了比赛，但是当我尝试设置语音聊天时它什么也没做，我做错了什么？它运行时不会抛出错误。这是我用来进行语音聊天的代码。

- (void)establishVoice
{
    if (![GKVoiceChat isVoIPAllowed])
        return;

    if (![self establishPlayAndRecordAudioSession])
        return;

    NSLog(@"Did stablish voice chat");

    chat = [match voiceChatWithName:@"GeneralChat"];
    [chat start]; // stop with [chat end];
    chat.active = YES; // disable mic by setting to NO
    chat.volume = 1.0f; // adjust as needed.

    chat.playerStateUpdateHandler = ^(NSString *playerID, GKVoiceChatPlayerState state) {
        switch (state)
        {
            case GKVoiceChatPlayerSpeaking:
                // Highlight player's picture
                NSLog(@"Speaking");
                break;
            case GKVoiceChatPlayerSilent:
                // Dim player's picture
                NSLog(@"Silent");
                break;
            case GKVoiceChatPlayerConnected:
                // Show player name/picture
                NSLog(@"Voice connected");
                break;
            case GKVoiceChatPlayerDisconnected:
                // Hide player name/picture
                NSLog(@"Voice disconnected");
            break;
        } };
}

其中建立播放和记录音频会话是：

- (BOOL) establishPlayAndRecordAudioSession
{
    NSLog(@"Establishing Audio Session");
    NSError *error;
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    BOOL success = [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
    if (!success)
    {
        NSLog(@"Error setting session category: %@", error.localizedFailureReason);
        return NO;
    }
    else
    {
        success = [audioSession setActive: YES error: &error];
        if (success)
        {
            NSLog(@"Audio session is active (play and record)");
            return YES;
        }
        else
        {
            NSLog(@"Error activating audio session: %@", error.localizedFailureReason);
            return NO;
        }
    }

    return NO;
}

该代码成功记录了“Did stablish voice chat”，所以它确实运行了代码，但是当我开始说话时，它似乎既没有得到声音也没有发送它。我究竟做错了什么？我错过了什么吗？PS 我没有让 GKVoiceChatPlayerConnected 被解雇。

确保两个设备上的 wifi 都已打开。

（我为此苦苦思索了好几个小时，终于意识到我不小心关闭了我的 2 个测试设备之一上的 wifi）
