Yes, you can take out a view from the view hierarchy inside a window to make it invisible (although IIRC Apple recommends to just hide the view in that case) or to move it from one window to another. You can freely change the view's dimensions and contents while it is not associated with a window. However, > Does it make sense to also draw it? No. In the end, it is the window you are drawing to that determines the graphics context and without that there is nothing you can draw. Also, usually you don't draw a view yourself, but only when the window that contains the view asks you to do so. This is for optimized drawing, so that you can restrict drawing to just that part of a window that is actually visible. If you really need to draw a view that is not visible, create an offscreen window for that and attach the view to it.
