There is no dedicated framework for that on the Mac. I guess it depends on what touch screen you're using and how the manufacturer implements things.
I think most touch screens just simulate mouse clicks, so your best friend will probably be NSEvent (or all the AppKit methods that get called when an event arrives, like -mouseDown:). NSEvent is also how to get pressure data from graphics tablets (like WACOMs), and some essential trackpad gestures like pinch/zoom, swipe and rotate.
There's also an NSTouch class that's worth checking out for trackpad gestures. Maybe touchscreen manufacturers support that as well, these days.
