Is it possible to draw grid lines using AVFoundation Framework in Objective c

Question

I am creating the app like VSCO Cam, so I imported AVFoundation framework to my project and used AVCaptureSession to create the custom camera.I also need to create the custom filters as same as VSCO Cam. Now I want to add the gridlines on the camera by clicking a button.I searched for more tutorials, but I couldn't sort it out.I tried drawing grid lines using AVCaptureManager by seeing this link how to draw grid lines when camera is open avcapturemanager, But I cannot overlay the view with camera view.I'm a new bee to development. Thanks in advance.

Yes.Create a tranparent UIView and place it on top of the camera preview. Then you can draw what ever you like in that view or you can append the image.
