This Xcode project shows how to add a parallax Header view to a UITableView with horizontally scrollable UICollectionview for selecting images.
The requires Xcode 8 and Swift 3.0 to run.
To add parallax header to scroll view (UITableView) you need just create view and set it to your scroll view (UITableView).
//create view as header view
let parallaxHeight: CGFloat = view.bounds.height - (sliderHeight + sliderPadding)
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
collectionParallaxView = UICollectionView(
frame: CGRect(x: 0, y: 0, width: view.frame.width, height: parallaxHeight),
collectionViewLayout: layout
)
collectionParallaxView.isPagingEnabled = true
collectionParallaxView.showsHorizontalScrollIndicator = false
collectionParallaxView.backgroundColor = UIColor.white
headerBuilder.setup(
collectionView: collectionParallaxView,
images: images,
handler: { [weak self] selectedIndexPath in
self?.sliderBuilder.selectCell(forIndexPath: selectedIndexPath)
})
tableView.parallaxHeader.view = collectionParallaxView
tableView.parallaxHeader.height = parallaxHeight
tableView.parallaxHeader.minimumHeight = 0
tableView.parallaxHeader.mode = .centerFill
tableView.parallaxHeader.parallaxHeaderDidScrollHandler = { parallaxHeader in
print(parallaxHeader.progress)
