As part of the caching mechanism in my app, I need to be able to
associate data with image files (PNG in this case). Right now I am
storing it in separate plist files, but soon I will have many more
files to manage, and it could become a little bit unwieldy. Is there
a way to embed data (basically a couple of strings) directly in the
image file?
Sure, that's a standard part of the PNG file format specification.
You can define your own extension chunks and store whatever you like in
them.
