如何获取资产目录组中的所有图像名称？

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 the relevant folders. The code using FileManager is not working anymore as it can not find any folders (due to the assets being compiled into a .car file).

How should I approach this?

Answer 1

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

Answer 2

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.
