Using .jp2 images in an array

Question

I am using images in my app which need to have transparency. They are currently .png files, but converting them to .jp2 (JPEG 2000) reduces the file size considerably. I added them to the Xcode project, but they are not loading when I run the app. Does this mean Xcode/Objective C does not support .jp2 files?

Answer 1

You have there files supported by apple, and i can't see jp2. So my answer is: no, jp2 is not supported.

Answer 2

Here you can find what images are supported by iOS UIImage. .jp2 format isn't on that list. So it's not supported.
