I'll just mention that in Panther, you can use -selectedRowIndexes to get an NSIndexSet of the selection..
Which is a pain to iterate, so I'll just mention that with CocoaSTL <http://www.top-house.dk/~aae0030/cocoastl/> you can iterate an NSIndexSet like this:
NSIndexSet* indexSet = ...;
foreach(it, beginof(indexSet), endof(indexSet))
printf("%d\n", *it);
I am really puzzled that Apple does not provide a way to easily iterate objects instantiated from this class...

This seems straightforward enough:

NSIndexSet * indexSet = ...;

Forwards:
unsigned currentIndex = [indexSet firstIndex];
while (currentIndex != NSNotFound)
{
//...
currentIndex = [indexSet indexGreaterThanIndex:currentIndex];
}

Backwards:
unsigned currentIndex = [indexSet lastIndex];
while (currentIndex != NSNotFound)
{
// ...
currentIndex = [indexSet indexLessThanIndex:currentIndex];
}
