See -sortUsingFunction:context: in NSMutableArray’s documentation. As
Ricky Sharp has already mentioned, there’s also -sortUsingSelector:,
however if you’re comparing partly with external data you might like
having the void * context provided by this method.

How do you sort an NSMutableArray, when the difference between the
two objects is determined by information not contained completely
within the objects themselves. ie in Java you can implement a
Comparator that takes two objects to compare then. Is this similar
in Cocoa?
ie in this case I need to apply a mathematical algorithm using
information from each object to determine which one is greater than
the other.
Thanks!
