No, in general there is no way. You’d have to make a copy of the object, keep that around, and then later call CFEqual on the current object and the copy … except that (a) there is no generic CFCopy function, and (b) if there were it would only make a shallow copy, so you wouldn’t be able to detect changes to nested objects (i.e. an item in a CFArray changing.) What’s the bigger picture? What do you want to use this for? —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
