You don't "draw" an NSView. An NSView (or subclass) is either a subview of your view, or it isn't. And you mustn't add or remove subviews during your -drawRect: method; during drawing, the set of subviews really needs to remain stable in order for Cocoa's optimised drawing machinery to function correctly.
Kind regards,
Alastair.
