iPhone前摄像头后视镜

我的应用程序与iPhone的前置摄像头配合使用。当我试图拍摄我的照片时，出现了一个问题。 当我在镜头中向左转弯时，它显示为向右转弯。就像一面镜子。我怎么能避免这个

AVCaptureDeviceInput *newVideoInput;
AVCaptureDevicePosition currentCameraPosition = [[videoInput device] position];

if (currentCameraPosition == AVCaptureDevicePositionBack)
{
    currentCameraPosition = AVCaptureDevicePositionFront;
}
else
{
    currentCameraPosition = AVCaptureDevicePositionBack;
}

AVCaptureDevice *backFacingCamera = nil;
NSArray *devices = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
for (AVCaptureDevice *device in devices) 
{
    if ([device position] == currentCameraPosition)
    {
        backFacingCamera = device;
    }
}
newVideoInput = [[AVCaptureDeviceInput alloc] initWithDevice:backFacingCamera error:&error];

我也面临同样的问题+这是我的荣幸！当您捕获快照或录制视频时，它将处于正确的模式。您使用的任何相机都会向您显示镜像图片，但录制后的实际输出将正常。
