[MonoTouch] Capturing a signature

[Dean Cleaver]

I have to capture a customer's signature on the iPhone screen, and save it for later use. Anyone got any pointers on how to go about it?

I see that a UIResponder has touch events, so I can track a finger. Am presuming that if I track a finger, I can draw directly to the view, but how do I capture that drawing later? Or should I also be drawing to a UIImage in the background or something like that?

Just wondered if anyone had any pointers to get me started in the right direction.
