How to apply parallax effect to UITableView header that contains horizontal UICollectionView?

Question

I created screen that contains UITableView . The tableView header contains horizontal UICollectionView and that collectionView contains cells with imageView and some other view.

The question is how to apply parallax effect to all view in the tableView header?

Answer 1

Implement the UIScrollViewDelegate method scrollViewDidScroll . There you can examine the contentOffset of the table view and modify the collection view height (via the constant of a NSLayoutConstraint ) and its contentOffset .
