I'm running into some issues with having a lot of UIImages in memory, so I was wondering if there is any way of using PVRTC images instead of PNGs in UIImages.
Is it possible to use PVRTVC textures in UIImages?

No, it is limited to the OpenGL domain.
One technique that I have used in the past is to keep compressed PNGs in memory. As
NSDatainstances. And then uncompress them on demand withUIImage'simageWithData:method.It does depend on the 'complexity' of your images though. In my case the images were 'simple' and resulted in fine performance.
You can also look at my animation framework at Github:
http://github.com/st3fan/iphone-animation
It uses a similar technique but uses run-length encoding for the compressed images in memory. Results in larger data (but still way smaller than uncompressed) but decompresses really quickly compared to PNGs.
