How to use?
StackedItemsLayout
The carousel has been implemented as a custom UICollectionViewLayout
: StackedItemsLayout
. You can use this layout directly in a UICollectionView
that uses paging:
let collectionView = UICollectionView(frame: .zero, collectionViewLayout: StackedItemsLayout())
collectionView.backgroundColor = nil
collectionView.alwaysBounceHorizontal = true
collectionView.clipsToBounds = false
collectionView.isPagingEnabled = true
// configure the collection view as any other collection view
StackedItemsView
You can also use the convenience wrapper view, StackedItemsView
. This is a generic view that takes an ItemType and CellType as generic parameters and handles the collection view for you:
let stackedItemsView = StackedItemsView
()
stackedItemsView.items = [.red, .blue, .brown, .green, .orange, .purple, .yellow, .gray, .cyan, .magenta]
stackedItemsView.configureItemHandler = { item, cell in
// configure your cell here - it already has some shadow and corner radius parameters set on
// the cell itself.
}
stackedItemsView.selectionHandler = { [weak self] item, index in
// handle item selection here
}
view.addSubview(stackedItemsView)
