I have to create sections with grouped autoresizing cells. To attain the impact of grouping, I take advantage of background as a ornament merchandise. As I would like the background to go beneath the background of earlier part, I alter its contentInsets. Nonetheless, the ultimate outcome seems like this:
The part 2 containing Cells 3 and 4 is overlapping the background of part 1. If I add extra sections, there’s a sample, that each second part background overlaps the earlier part background.
That is how I setup my collectionView:
collectionView.delegate = self
collectionView.dataSource = self
collectionView.register(DesignTestCollectionCell.self)
collectionView.backgroundColor = Coloration.clear
collectionView.alwaysBounceVertical = false
collectionView.alwaysBounceHorizontal = false
collectionView.showsHorizontalScrollIndicator = false
collectionView.showsVerticalScrollIndicator = false
collectionView.collectionViewLayout = createCompositionalLayout()
That is the code for including part background:
func addSectionBackground(
high: CGFloat = 0,
main: CGFloat = 0,
backside: CGFloat = 0,
trailing: CGFloat = 0
) -> CompositionalSection {
let backgroundItem = NSCollectionLayoutDecorationItem.background(
elementKind: DecorationViewType.background.rawValue
)
backgroundItem.contentInsets = NSDirectionalEdgeInsets(
high: high,
main: main,
backside: backside,
trailing: trailing
)
decorationItems = [backgroundItem]
return self
}
Might you assist me discover a technique to power earlier part background to at all times overlap the next part background?
