Question

I have a UICollectionView that horizontally scrolls to show one UICollectionViewCell at a time. Each UICollectionViewCell the has a vertically scrolling UIScrollView as subview for scrolling the contents of the cell. It is only 90 % or so of the inner part of the UICollectionViewCell that is covered by the UIScrollView – i.e. the outer frame of the cell is not covered by this.

It turns out that the part of the UICollectionViewCell that is covered by the UIScrollViewcancels the UICollectionView delegate didSelectItemAtIndexPath. Thus when a simple tap happens within the UIScrollView this method is not invoked, whereas if the tap happens on the outer part of the cell, i.e. outside the UIScrollView, this method is invoked.

Any suggestions as to how to achieve a setup where it is possible to invoke the didSelectItemAtIndexPath method even when the tap happens within the UIScrollView?

Answer 1

The tap on the UIScrollView is used to see whether scrolling should be done.

You should catch the single tap on the UIScrollView itself and pass it on to the surrounding UICollectionViewCell.
