One easy trick, if you want to achieve it is replacing parent scrollview with normal container view. Adding a pan gesture on container view, you can play with top constraint of first view to assign negative values. You can keep a check of page View's origin if it achieves to top you can start assigning that value on content offset of the pageView's child view. Until user achieves the table view in a state of top most view in container view, you can keep page tableView's scrolling disabled and allow scrolling manually by setting content offset. So initially the page view height will be collapsed (or say out of screen) or less at bottom. Later on scrolling down it will expand to take more space.

Gesture will automatically stop responding if out of frames say on nav bar or other view outside container view.

Gestures are a key to user interactive transitions used in many apps. You can mimic scroll for a certain time with it.
