Storyboard in IOS 5 SDK but also target IOS 4 /3?
提问by kkurni
I love the idea of using storyboards, but unfortunately when I try to test this using IOS 4,
I change the deployment target to IOS 4 and I can't compile this anymore.
it said that Storyboards is not supported for IOS 4.3 or later.
我喜欢使用故事板的想法，但不幸的是，当我尝试使用 IOS 4 进行测试时，我将部署目标更改为 IOS 4，并且无法再编译它。它说Storyboards is not supported for IOS 4.3 or later。
So is it useful to use storyboards? How can I write iPhone apps using storyboards so that they can be compatible with IOS 4?
那么使用故事板有用吗？如何使用故事板编写 iPhone 应用程序，以便它们与 IOS 4 兼容？

I don't think that there's a reasonable way of doing it.
我不认为有一个合理的方法来做到这一点。
You couldinstantiate your Storyboards programatically (I think) but then you'd need something to fall back on on pre-iOS5 devices. And what would that be? Probably XIBs... which also continue to work on iOS5. You'd end up implementing everything twice. So, as I say, it may be possible but it's probably not practical.
您可以以编程方式（我认为）实例化您的 Storyboard，但随后您需要在 iOS5 之前的设备上依靠一些东西。那会是什么？可能是 XIBs ......它也继续在 iOS5 上工作。你最终会实施两次。所以，正如我所说，这可能是可能的，但可能不切实际。
