If that's the case, why not just provide your library's API in terms of NSPredicate objects? Then if your users want to use a predicate string (rather than an NSPredicateEditor or other form of direct instantiation) they still trivially can, but it's on them to get the syntax correct rather than on you to try to figure out their intent. -- Chris _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
