Well, if you're just using dummy values as the objects in a dictionary,
then why not just use an NSSet instead?

What is the best way to filter out duplicate NSStrings from an
NSMutableArray?
Traditional Perl wisdom is that, whenever you find yourself using the
words "unique" or "duplicate," you should be thinking about a hash
instead of an array. In Objective-C terms, that would be an
NSDictionary instead of an NSArray. That is, when you're building the
list, instead of doing this:
[myArray addObject: aString];
Do this:
[myDictionary setObject: @"" forKey: aString];
