XCode is an IDE. iOS SDK (Software Development Kit) is a set of development tools (mostly in the form of libraries) that you use to create applications with.
XCode 是一个 IDE。iOS SDK（软件开发工具包）是一组用于创建应用程序的开发工具（主要以库的形式）。
As mentioned by @VladTheImpaler you are probably trying to open an application written with the iOS4.2 SDK in an environment that only has the iOS3.2 SDK libraries. This will cause incompatibilities and missing links etc.
正如@VladTheImpaler 所提到的，您可能正在尝试在只有 iOS3.2 SDK 库的环境中打开使用 iOS4.2 SDK 编写的应用程序。这将导致不兼容和丢失链接等。

As far as I know XCode is the program that you are using to write and compile. The different SDKs are containing the different APIs for what you're writing.
据我所知，XCode 是您用来编写和编译的程序。不同的 SDK 包含针对您正在编写的内容的不同 API。
So probably you are using stuff that is supported in 4.2 but isn't in 3.2 of iOS and since the APIs are missing, that's why it is not running.
因此，您可能正在使用 4.2 中支持但 iOS 3.2 中不支持的内容，并且由于缺少 API，这就是它没有运行的原因。
