This assumes you're sorting an array of objects that have a "createdDate" field.

Any object that conforms to Key Value Coding (KVC) such as NSManagedObjects or NSDictionaries will work with this.

So, you could use it to sort Core Data objects or JSON parsed into dictionaries for instance.

There are more flexible ways to sort NSArrays using blocks or custom methods, but this covers 90% of cases
