I’ve posted before about how the new PDF support in asset catalogs doesn’t really do what we expect (offer resizable vector assets). To make up for that, here’s a class that loads images from PDF files directly, building them to whatever UIImage size you need. Supply a path to the image and a target size, height, or width. If using a size, the functions will scale-aspect-fit to that target. With width or height, they’ll use the built-in aspect and build an appropriately sized partner dimension.
This class is part of my useful things repo, which is where I stash stuff that people may generally find useful. A bunch of classes and utilities are tied to my InformIT write-ups, but others meander there over time because I was inspired for whatever reason.
