enumeration

I have an NSArray, with objects ordered like so:

a
b
c
d
e
f

I would like to enumerate through this array in this order:

c
d
e
f
a
b

i.e. starting at some point that is not the beginning, but hitting all the items.

I imagine this is a matter of sorting first and then enumerating the array, but I'm not sure if that's the best technique... or, frankly, how to sort the array like this.

Edit

Adding details: These will be relatively small arrays, varying from 3 to 10 objects. No concurrent access. I'd like to permanently alter the sort order of the array each time I do this operation.
