how to add older SDK's to xcode 4

Question

Good Evening, The problem is that i have both xcode 3.2 and xcode 4 and i want to transfer the installed sdks from xcode 3.2 to xcode 4.0. is that even possible?? I am building an app for 3.1.3 in xcode 3.2 and i want to transfer my work to xcode 4.0. Is it as simple as copying the sdks from one folder to another?

I hope my question is clear.

thank you,

Answer 1

I think you can just set the iOS deployment target to 3.1 in your project settings. I don't know if XCode will actually warn you if you're using an API call that's only available in 4.0 though.

如果要在较旧的设备上进行测试，可以在xCode首选项/下载/组件上安装模拟器。
