问题
In the latest iteration of Xcode, Xcode 4.0, the 10.4 SDK is no longer included. However, I still need to support 10.4 and PowerPC builds.
I have installed latest Xcode 3.2.6 which still includes 10.4 support. Then I installed Xcode4. Has anyone found a simple way to "cheat" and get Xcode4 to use 3.2.6's SDKs?
回答1:
Yes, I did :) See here.

XCode 4.0 supports deploying to Mac OS X 10.4 right out of the box, so you shouldn't have to do anything special.
For example, I created a project then selected the project and right there, there is a field called "Deployment Target" where you can select 10.4, 10.5 or 10.6. QED
