iphone - 如何静音 AVCaptureDevice？

Question

我有摄像头，即 AVCaptureDevice，我确定闪光灯已关闭，但现在我需要关闭相机噪音，有办法做到这一点吗？

NSArray* cams = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
    AVCaptureDevice* device = nil;
    if(isBackCamera)
    {
        device = [possibleCameras objectAtIndex:0];
    }
    else
    {
        device = [possibleCameras objectAtIndex:1];
    }

    device.flashMode = AVCaptureFlashModeOff;

我认为苹果不允许你这样做
