Question

Is there some way I can do something like:

@implementation MyView

- (void)drawRect:(CGRect)rect
{
   // Get the thing I'm supposed to draw (CGImageRef, pattern, etc.) and draw it
   // i.e. not real code
   CGContextDrawWhatever(self.objectThatHoldsDrawing.drawing);
}

Answer 1

Have a look at CGPathRef, CGLayer (or maybe even just CALayer, but that’s mostly equivalent to a drawRect: method) and rendering (e.g. buffering) to image context and just renderind the image.
