How to have a floating modal controller on top of another controller and have interaction with them at the same time

问题

I want to know what is best approach for having a floating modal controller on top of another controller like this image:

As you see, top section of this page is a modal view.

I can implement this top view in the below controller class but I want to have a separate controller for it, but I don't know how to present that class so user have control of the both controllers in same time.

If I create a regular transparent class & present it modally, user will lost interaction contact with the lower controller.

回答1:

Base of @Shivam Gaur suggestion.

I created a custom class & built every thing for handling that top view in there.

But still I need to handle interactions with subview items in my lower class but its worth the try.

Here is this GitHub link of this project.
