Edit Question
Title
Body
I have an NSArray formed with objects of a custom class. The class has 3 (city, state, zip) string properties. I would like to get all unique state values from the array . I did read through the NSPredicate class but couldn't make much of how to use it in this case. The only examples I could find were for string operations. Can someone please help me out?
