Thank you for your replies... I guess the issue is really more related to the fact that I didn't understand how NSStrings work with the -isEqual: function. I have been reading up on it, and have read some interesting things including: http://www.drobnik.com/touch/2009/11/the-world-on-an-nsstring/ The author of the article is somewhat unsure whether using -isEqual: is safe, but after looking at the [NSString hash] documentation I feel confident in my current implementation. Short answer... yes. NSSet and subclasses *effectively* compares the value of the NSString and not the object address. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
