Why does drawRect: work without calling [super drawrect:rect]?

Question

I\'m overriding drawRect: in one of my views and it works even without calling [super drawrect:rect]. How does that work?

- (void)drawRect:(CGRect)rect{  
    C

Thanks.. There is no need to call super, because the superclass here is UIView, whose drawRect: does nothing.

In general, we call setNeedDisplay if we want recall drawRect for drawing.
