Re: NSPointerArray on iOS - truly __weak?
That just repeats the question - as I said (and you quoted), are the docs just lying? The point is that I prefer not to guess. I would like to be told officially that on iOS (not Mac OS X) these classes are doing ARC-__weak references under ARC when asked for weak behavior. m.
