What is the most efficient way to sort an NSSet?

What's the most efficient way to sort objects in an

NSSet
/
NSMutableSet
based on a property of the objects in the set? Right now the way I am doing it is by iterating through each object, add them to a
NSMutableArray
, and sort that array with
NSSortDescriptor
.

Answer

try using

[[mySet allObjects] sortedArrayUsingDescriptors:descriptors];

Edit: For iOS ≥ 4.0 and Mac OS X ≥ 10.6 you can directly use

[mySet sortedArrayUsingDescriptors:descriptors];
