So here's some background. I have some UICollectionViewCell that have transparent backgrounds, but I still want them to have shadows, which don't really render as expected (around the view, instead of around each opaque subview\element in it) so I was thinking of taking a screenshot over the parent view and setting that as a background image to get "fake" the view being transparent. What would be the best way to do that?

Essentially:

Get a screenshot of the screen below a UICollectionViewCell
Clip the screenshot to the frame/bounds of the cell

I saw this post, but I doesn't seem to work for whatever reason. drawHierarchy keeps returning false. I'm also assuming it gets the entire view hierarchy, not the views below the one requested it

Nope, and I'm not sure what the issue is – Programmer Unextraordinair Jan 23 '18 at 21:27
I think I might help you on this stuff, but first you should clarify couple of things, like: "that have transparent backgrounds, but I still want them to have shadows" what you mean? Might you post an example of what you want to achieve? – mugx Jan 24 '18 at 12:17
