ios automatic migration from images to assets catalog

Question

I have really large number of images just in Images folder of my project (just @1x and @2x.png files). It's time to support @3x displays and I've decided to move to assets catalog. Are there any tools/scripts to automate this?

Answer 1

Normally you already have an Asset Catalog because of your AppIcon. If not, choose File:New:File ... and then select iOS Resource:Asset Catalog.

The images you want to import should be named properly: image.png, [email protected]. If you target both devices: image~iphone.png, image@2x~iphone.png, image~ipad.png, image@2x~ipad.png.

Then select Asset Catalog and press +. Choose the folder with the images you want to import.

Like that it´s very simple to import large numbers of pictures and you can have the same folder structure in your Asset Catalog, as you had before.
