  • 0

I am creating a new application and am planning to start with ios5 as it supports storyboards. However, I am not sure if the app that is compiled with ios5 runs on ios4 as we are looking at kind of a forward compatibility. Since ARC is a compile time feature, I am guessing that is not a problem. However, the calls like prepareForSegue or performSegueWithIdentifier depend on ios5 api’s. However as the code is built, I am wondering if the executable assembly is capable of running on ios4 devices. Can some please shed some light on this?

Also, if the answer is a strict NO, do I need to go back with traditional NIB‘s for the app? Are there any selective features that may work and that may not?

    The UIStoryboardSegue is iOS 5 only, thus the app will not run on iOS 4. Since it not a compile time feature, you will have to go back to using NIB‘s.

    Any methods you use that are only available in iOS 5 will not work in iOS 4, thus meaning that any methods that deal with the storyboard will not work in iOS 4.
