Remove a drawn NSRect or other drawn object
How do I remove a drawn NSRect or other object other than drawing开发者_开发问答 another rect over it?
Assuming you drew the rect in drawRect:
, all you need to do would be to exclude the rect from the list of objects to be drawn and call [view setNeedsDisplayInRect:theRect]
. theRect
here would be the CGRect
equivalent.
