For example, I want to draw something directly to an UIView. I need an CGContextRef, but I don’t want to make a new one since that would eat up too much memory. Can I obtain the CGContextRef from an UIView?

Outside of the redraw call, I do not believe so. I remember trying this myself a while ago. Sorry I can’t be more specific, but I’ve not touched the iPhone SDK in months.
