Hello cocoa-dev list: My apologies if this is incorrect and/or totally misinformed for this list, but I seem to be missing something obvious. In my application I've subclassed UIView and use the -drawRect:/-setNeedsDisplay approach to draw lines into the view. Is there a way to set up the drawing such that it adds to the existing image instead of redrawing all of it? For example, if I generate a random line in each -setNeedsDisplay invocation of -drawRect, I'd like to retain in the resulting image the lines previously drawn.
