For example, with this dictionary: mutableDict = { "A" = 2, "B" = 4, "C" = 3, "D" = 1, } I'd like to end up with the array ["D", "A", "C", "B"] . My real dictionary is much larger than just four items, of course. 回答1: The NSDictionary Method keysSortedByValueUsingComparator: should do the trick. You just need a method returning an NSComparisonResult that compares the object's values. Your Dictionary is

I'd like to take any NSDictionary and process each level in hierarchical order. 1) This data is coming from validated JSON. Is it safe to say that the NSDictionary created from a framework such as SBJSON (JSON Framework) would only result in a combination of nested dictionaries, arrays, and arbitrary leafs? 2) How can a generic traversal be done using fast enumeration that works for both arrays and dictionaries? With the code below, once I get to
