Howdy,
In my app I've decided to isolate the AddressBook functionality into a
separate bundle and only load it if the user is running 10.2 or later.
Rather than implement exporters as plug-ins, I'm just creating an
ABGruntWork object that does the grunt work and my exporter simply
calls it.
The above link gives good examples of detecting the OS version
including a Gestalt based one. Is there a Cocoa, i.e., non-Carbon,
equivalent to Gestalt? (I know that I can call the Carbon version.)
In this specific case, I don't want to check for version 10.2 of the
OS, I want to check to see if the AddressBook API is available. If
there isn't a Cocoa Gestalt equivalent, does Apple maintain gestalt
selectors for all the newfangled "Cocoa stuff"? If not, should I just
punt and depend on the OS version?
