I’m getting the select items from a table view with:

NSIndexSet *selectedItems = [aTableView selectedRowIndexes];

what’s the best way to get the indexes in a NSArray object?

    Enumerate the set, make NSNumbers out of the indexes, add the NSNumbers to an array.

    That’s how you’d do it. I’m not sure I see the point in transforming a set of indexes into a less efficient representation, though.

    To enumerate a set, you have two options. If you’re targeting OS X 10.6 or iOS 4, you can use enumerateIndexesUsingBlock:. If you’re targeting earlier versions, you’ll have to get the firstIndex and then keep asking for indexGreaterThanIndex: on the previous result until you get NSNotFound.
