No. Here is the OP's code:
NSArray *setTheSpeaker;
setTheSpeaker = [[NSArray alloc]
initWithObjects:connectToThisSpeaker, nil];
[Airfoil connectTo:setTheSpeaker password:nil];
The OP's ObjC code was wrong. His AS code was correct. His
understanding of how the AS code worked may have been incorrect;
that's not uncommon - many AppleScript users don't properly grok it
either.
You are confusing that with the AppleScript he tried to emulate. I
accurately described what the code he posted did, and that it did not
line up with what he was trying to do.
I think there's some confusion over the confusion. :) You stated: "the
command wants an NSArray containing references to "speaker" objects",
which is wrong. The command wants a *single reference* that identifies
one or more "speaker" objects.
i.e. Even if the OP's ObjC code had passed an NSArray of SBObjects, it
would still be wrong. To emulate his AS code, he'd need to use an
NSElementArray (which isn't really an array at all, but only pretends
[badly] to be one) to as the argument to -connectTo:.
Like I say, Apple event IPC makes absolutely no sense if you try to
think about it in OOP terms. AppleScript syntax looks a bit OO-like,
which lulls unwary OO programmers into all sorts of misconceptions.
But this particular bit of mechanics actually draws on ideas from the
world of relational databases, so you'll have more luck viewing it
through SQL-coloured glasses than Cocoa-coloured ones.
Hope that clarifies (inasmuch as anything AppleScript-related ever can
be),
