Tutorial :NSFetchedResultsController.sortDescriptor by KeyPath

Question:

How can I set my fetchedResultsController.sortDescriptors to contain a sortdescriptor that uses a keypath, for instance, such as @"foo.name"?

Cheers

Nik

Solution:1

Despite NSSortDescriptor's use of the name “key”, it actually takes a key path, as described in the documentation. So, just create an NSSortDescriptor with your key path as the “key”, and use that.
