[MacRuby-devel] How to use NSIndexSet with tableView data

[Eloy Duran]

Since an Array is a NSArray: http://bit.ly/de3kxd, maybe something
like the following?

$ macirb
irb(main):001:0> a = ['apple', 'tuna', 'orange']
=> ["apple", "tuna", "orange"]
irb(main):002:0> indices = NSIndexSet.indexSetWithIndex(1)
=> #<NSIndexSet:0x20023fe80>
irb(main):003:0> fish = a.objectsAtIndexes(indices)
=> ["tuna"]
