In Quartz2D, can I draw any shapes without using drawRect:(CGRect)rect method?
Yes. If you want to draw to a bitmap (as one example) and produce a CGImage, you could certainly create a CGBitmapContext, then use CoreGraphics as usual using that as your context.
If you want to draw to the display, do your work from within
drawRect:, using the supplied graphics context.
