Hi, you verfied this? I was under the impressions
that
performSelector same as NSInvocation transparently
'unwraps'
NSValues........or maybe only NSInvocation!?

I think you're imagining things here. Why would - performSelector:withObject: ever want to do that? For a start, you wouldn't be able to pass an NSValue.

I don't see why not. It could behave the same as KVC, which works both with scalars and NSValues.

And if you wanted to send an NSValue *object* as an argument of a message?


Besides, as I said, it's called performSelector:with**Object**:, not performSelector:withObjectOrMaybeSomethingElseStoredInAnNSValue: :-)

(OK, I'm exaggerating for effect, but the point is that the behaviour you're describing is not performing a selector with an object, it's doing something quite different.)

Kind regards,

Alastair.
