Changing GUI Skin button states with touch input

Hi, I'm using the (now old I guess) Unity GUI system, and have a few buttons. They're set up with a GUISkin so the text and texture of a button changes when you hover over or click on a button.

This all works fine visually for mouse input, but not for touch; obviously hover wouldn't work, but the Active state does work either. Is there anyway to set that up in the GUISkin? Or do I have to find another method?

Just to clarify, the buttons themselves work and function, it's just the visual changes set up in the GUISkin that doesn't work.
