ios - UITapGestureRecognizer Dismiss keyboard & UICollectionView conflict

Question

I have a UIScrollView with numerous stack subviews.

I have a UITapGestureRecognizer that dismisses the keyboard and this works.

let tap = UITapGestureRecognizer(target: self, action: #selector(dismissKbd))
self.view.addGestureRecognizer(tap)

One of my subviews is a stack view that holds a collection view.

stackView = UIStackView()
scrollView.addSubview(stackView)
stackView.axis = .horizontal
stackView.anchor(top: notesTextView.bottomAnchor, left: scrollView.leftAnchor, bottom: scrollView.bottomAnchor, right: scrollView.rightAnchor, paddingTop: 8, paddingLeft: 2, paddingBottom: 2, paddingRight: 2, height: 400)
let child = ImageGalleryViewController()
stackView.addArrangedSubview(child.view)
child.didMove(toParent: self)

Problem:

This results in:

1. Keyboard will dismiss when screen tapped
2. didSelectItemAt only works when two fingers are used on a cell

I assume this is to do with a conflict of gesture recognizers.

I would appreciate any guidance on how to make this work. I assume it's to do with the focus of the gesture recognizers?

Answer 1

I think you can handle dismiss keyboard when scollView scrolled or offsetY is a constant number. you never need to dismiss the keyboard with gestures.
