使用XCode 4.2，是否可以使用Storyboard制作兼容iOS 4的应用程序？

Question

I have searched for this answer, and have had mixed reviews. Some say it SHOULD be possible (like using ARC), and some say it's not possible. Can anyone give me a definitive answer either way?

Answer 1

According to apple NO. Apple always said storyboarding would only be for iOS5. But prove it to yourself. Start a new project, check use storyboarding, create the project. Then change the target iOS to 4.3 and run, the view will not load.

ARC will run even down to 4.2, though you can't use weak references below 4.3.
