I use core data, with several entities linked via relationships.
Entity A has a to one relashionship (named: 'relat') to entity B.
Entity B has an attribute named 'attrib'.
I have an NSarray containig A instances.
i would like to sort that array on relat.attrib key value.
[anArray sortedArrayUsingDescriptors: [NSArray arrayWithObject: @"relat.attrib"]] does not work, beause 'relat.attrib is searched a an A key value.


Refer to the API documentation for -sortedArrayUsingDescriptors:.

The array is an array of NSSortDescriptors, not an array of strings/ keypaths.
