I have cams which is AVCaptureDevice, I made sure the flash was off but now I need to shut the camera noise up, is there a way to do that?
NSArray* cams = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
    AVCaptureDevice* device = nil;
    if(isBackCamera)
    {
        device = [possibleCameras objectAtIndex:0];
    }
    else
    {
        device = [possibleCameras objectAtIndex:1];
    }
    device.flashMode = AVCaptureFlashModeOff;
