I think you're labouring under a misapprehension. NSMutableSet doesn't 'have a' predicate. You can apply a predicate to a set (mutable or not) to return a new set whose members match the predicate. Once done, the set is a set - it has no memory of the predicate that was used to create it, nor the original unfiltered set. So you can re-use the set if you want, but it's usually cleaner and easier just to create a new set for a new purpose. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
