I’m creating an iOS app. Is that potential to open my app to do one thing to the image from the native Photographs App by double tapping an image?

I’ve studied the official doc and located creating picture modifying extension.
I’ve tried this implementation nevertheless it requires the person to click on the picture -> click on edit -> click on … -> click on the icon of my app. It’s too deep down and never what I would like.

One other method is to put in writing an analogous app because the Photographs. Is there the supply code of the native Photographs App on iPhone to reference from or ought to I write one on my own?

Thanks to your time.
