You can still target earlier iOS releases as deployment targets. To do so, for Objective-C you check at runtime whether a class has a selector that is only available in recent iOS versions. For C and C++, you take the address of the function (that is, get a pointer to a function), then test that it is non-NULL. If the desired API is not available, you either roll a fallback by hand, or just don't provide the feature that uses that API. In my App Warp Life, testing on iOS 3.0.6 found just one Objective-C selector that was not present. It was not hard to code up a fallback. But for the lack of storyboards writing your own from scratch would be too hard, so you would probably have to just not provide the feature that uses them when running on iOS builds prior to 5.0 -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com [email protected] _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
