With all the different OS versions I was wondering how it is possible to build one version of your app that can run on 2.2 but still use 3.0 or even 3.1 features when running on those platforms. Here is a great article that explains how it is done.

Steve, thanks for posting that link - I was wondering about it. I could imagine making a game thats playable on 2.2, but also could be played head-to-head via bluetooth if you have 3.0.
Any old-timers remember gestalt on pre-OSX Mac OS?

It let you write software that could run on different versions of Mac OS. You could take advantage of the more advanced libraries if they were available, or fallback to something simpler if they werent. I was wondering if you could do something similar with iPhone OS and it looks like you can.

ob1, that seems like it should be ok with Apple - but of course who really knows - and just bc it was ok doesnt mean it will be next week. Ballz has a "free", "full", and "pro" version (although strangely the "full" and "pro" versions are the same price).

Thanks for posting the link, that's saved me an afternoon of frustration.

Since that post things have changed slightly. You should check Apple's documentation on the subject, particularly about weak linking.
