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. Also, that kind of behaviour
doesn't fit the name of the method... you're asking it to perform a
selector *with an object* (i.e. the NSValue).
As for NSInvocation, obviously you can use NSInvocation to pass
arguments of pretty much any type you like.
Kind regards,
Alastair.
