For some reason, after installing the iPhone OS 3.0 SDK, I have no option anymore to create a 2.2 project. I don't want to develop for 3.0 because I target iPod touch, not iPhone. iPod touch users don't upgrade for 10 dollars so likely.
由于某种原因，在安装了iPhone OS 3.0 SDK之后，我再也无法创建2.2项目了。我不想为3.0开发，因为我的目标是iPod touch，而不是iPhone。iPod touch用户不会花10美元来升级。
Xcode creates projects with OS 3.0, and there is no option to switch to 2.2 SDK. Although for my existing projects I still can use 2.2 SDK in XCode.
Xcode使用OS 3.0创建项目，无法切换到2.2 SDK。虽然对于我现有的项目，我仍然可以在XCode中使用2.2 SDK。
How can I fix that?
我怎样才能解决这个问题呢?

The project is not really tied to an iPhone OS release, it's the "Base SDK" setting in your project. This is by default 3.0 in the new SDK.
这个项目并没有真正绑定到iPhone OS版本，它是项目中的“基础SDK”设置。在新的SDK中，这是默认的3.0。
To use an older OS, open the project settings (double click on the blue project icon in the Groups & Files section in the project window). Select the Build tab and chose another Base SDK in the Architectures section.
要使用较老的操作系统，请打开项目设置(双击项目窗口的group & Files部分中的蓝色项目图标)。选择Build选项卡，并在architecture部分中选择另一个Base SDK。
