UICollectionViewCell button callback - uicollectionview

Question

How to implement callback for example of button tap inside UICollectionViewCell's UIContentView or better how to do it in Combine way?
Cell registration inside UICollectionView:
let cellRegistration = UICollectionView.CellRegistration<MyCell, Item> { (cell, indexPath, item) in
cell.item = item
}
Cell:
class MyCell: UICollectionViewCell {
var item: Item?
override func updateConfiguration(using state: UICellConfigurationState) {
var newConfiguration = MyContentConfiguration().updated(for: state)
newConfiguration.name = item?.title
contentConfiguration = newConfiguration
}
}
Content configuration:
struct MyContentConfiguration: UIContentConfiguration, Hashable {
var name: String?
func makeContentView() -> UIView & UIContentView {
return MyContentView(configuration: self)
}
}
Content view:
class MyContentView: UIView, UIContentView {
let title = UILabel()
private var currentConfiguration: MyContentConfiguration!
var configuration: UIContentConfiguration {
get {
currentConfiguration
}
set {
guard let newConfiguration = newValue as? MyContentConfiguration else {
return
}
apply(configuration: newConfiguration)
}
}
init(configuration: MyContentConfiguration) {
super.init(frame: .zero)
// Create the content view UI
setupUI()
apply(configuration: configuration)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
private extension MyContentView {
private func setupUI() {
// UI stuff
}
private func apply(configuration: MyContentConfiguration) {
guard currentConfiguration != configuration else {
return
}
currentConfiguration = configuration
// Set data to UI elements
title.text = title
//etc..
}
}
Inside MyContentView there'll be a button for example. This button should be bound with item, so when it's tapped - some callback or Combine publisher should emit value, which I've got to catch inside my collection view.
How I've implemented this previously:
let cellRegistration = UICollectionView.CellRegistration<MyCell, Item> { (cell, indexPath, item) in
cell.item = item
//Catch value which is bound with associated item
cell.somePublisher
.sink { [weak self] in
guard let self = self else { return }
self.subscribePublisher.send($0)
}
.store(in: &self.subscriptions)
}
Cell:
class MyCell: UICollectionViewCell {
var item: Item?
public private(set) var somePublisher = CurrentValueSubject<Bool?, Never>(nil)
//UI setup, etc..
//Emit value for a button tap gesture
#objc func handleTap() {
somePublisher.send(true)
}
}
Is it possible to implement this behavior using UIContentView & UIContentConfiguration?
