Sometimes, when developing an App, I’m in the need of using some “stock” icons which, mostly, hide behind private APIs (e .g. the UIGlassButton) or are just not reachable for the “ordinary” developer.
This issue may easyly be solved by extracting all your iOS´ UIKit Artwork and just importing them as images into your project. I don’t really know wether this is legal, by the means of the image’s respective copyright holder, but at least as a placeholder this is a great help.
Check out the GitHub repo and have a look.
