This is a follow-up to an earlier question about "weak linking" -- it
turns out (Thanks, Ben) that you can weakly link frameworks, but this
is 10.2 only, so it only makes sense for apps which require 10.2 or
above.
I'd like to be able to have code that accesses the address book
framework, but still allow running under 10.1. I've seen mentions on
the archives of using NSAddressOfSymbol to manually load and execute
code as a possible solution -- but nothing really tangible!
Does anybody know of a snippet of code that I can look at to help me
figure out how to load the address book framework (is there any
initialization needed), and then invoke some of its methods from
Objective C?
(Matthew Formica said there was a technote forthcoming ... maybe soon?)
I'm stumped -- I may have to pull the address-book feature until I can
figure this out, or force all my users to be on 10.2, which I don't
think I'm ready for yet....
Regards,
Dan Wood
