How can I get all image names in asset catalog group?

Question

In my app I had a folder of images from which I was getting the names to use as keys to a Dictionary. I have now moved all images to an asset catalog and created groups for

Answer 1

You have two choices:

• Don't Do That. Go right on using a folder of images.

• Supply the keys in some other way. If you don't want to hard-code them into the code itself, you could make a text file. But of course you will have to keep that text file updated as you add / remove images.

You'll notice that I didn't say you could magically introspect the asset catalog. That's because you can't.

Answer 2

So (following matt's suggestion) here is what I did:

I created a RunScript build phase to run before compiling

and used a script to create a txt file with the names of the files that I can then use during runtime

#!/bin/sh
>./your_app_folder/fileNames.txt
for FILE in ./your_app_folder/Images.xcassets/actions/*; do
echo $FILE >> ./your_app_folder/fileNames.txt
done
