How to make UICollectionView headers stay fixed using sectionHeadersPinToVisibleBounds
Swift version: 5.6
Since the earliest days of iOS, UITableView has had fixed headers: as you scrolled within a table section the header stayed still, only moving off when another section reached the top.
This same functionality was added for UICollectionView in iOS 9.0, although it’s not enabled by default and only available with UICollectionViewFlowLayout.
To use it yourself, first make sure your collection view’s collectionViewLayout property is an instance of UICollectionViewFlowLayout, then set that flow layout’s sectionHeadersPinToVisibleBounds property to true. For example, you might write this:
if let layout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout {
layout.sectionHeadersPinToVisibleBounds = true
}There’s a similar property to make footers behave the same way: sectionFootersPinToVisibleBounds.
