    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
   // 设置为内置麦克风采集
   [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord mode:AVAudioSessionModeVideoRecording options:nil error:nil];
   
    // 切换输入麦克风
    AVAudioSessionPortDescription *builtInMicPort = nil;
    for (AVAudioSessionPortDescription *portDescription in audioSession.availableInputs) {
        if ([portDescription.portType isEqualToString:AVAudioSessionPortBuiltInMic]) {
            builtInMicPort = portDescription;
            break;
        }
    }

    if (builtInMicPort) {
        NSError *inputError = nil;
        [audioSession setPreferredInput:builtInMicPort error:&inputError];

        if (inputError) {
            NSLog(@"切换输入麦克风失败：%@", inputError);
        }else{
            NSLog(@"内置麦克风");
        }
    } else {
        NSLog(@"找不到内置麦克风");
    }
    [audioSession setActive:YES error:nil];
