If you want to iterate over the contents of a dictionary in alphabetical order of keys, I don't think there is a magic keypath that will allow you to operate on the dictionary itself. Your first thought was right: NSMutableArray * sortedKeys =[ [dictionary allKeys] mutableCopy]; [sortedKeys sortUsingDescriptors:<descriptors>]; //<--- create descriptor using key @"self" or else using an alternative means of sorting // now you can iterate over the dictionary in alphabetical order. I would only use sort descriptors if a) I had to sort based on more than one criterion, e.g. lastName, firstName or b) I was using a table view that manages sorting using descriptors. For simple sorts there are easier ways to do it. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
