How to save camera image in different folder (other than Camera Roll) in Ios?

I am developing an App where I am taking pictures from the Camera but all the pictures get stored in the Gallery. I would like to store all the pictures taken in this app to be stored in a different folder so that when users view the pictures in the app, it should show only the pictures taken using the app. Currently, all the pictures of the Gallery are being displayed which I do not want.

I want to create a folder, store camera pictures taken using the app in this folder then display all the images of the folder in the app.

Any suggestions would be appreciated.

Thanks in advance.
