Pass UICollectionView touch event to its parent UITableViewCell

Question

Here is the view structure:

The outer view is a UITableView.

Inside the UITableViewCell, there is a UICollectionView

Answer 1

Excellent answer by @tounaobun. Tested and it works as expected:

1) If you tap anywhere on the collection view that is not an item, then the table cell underneath will select just fine.

2) if you tap on the items in the collection view, then the table cell will not select and you can interact with the collection view normally (aka, scrolling, invoking didSelectItem, etc)

I converted to swift for reference:

Swift 3:

class TableCellCollectionView: UICollectionView { 

 override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
    if let hitView = super.hitTest(point, with: event) {
        if hitView is TableCellCollectionView {
            return nil
        } else {
            return hitView
        }
    } else {
        return nil
    }

}

Just add this class definition to your code (I have it in a utility file) and then change the collection view's class from UICollectionView to TableCellCollectionView and you should be all set.
