How do I import project settings from one Xcode project to another

I just upgraded my Xcode, and created a blank new project, and discovered that there's many new settings that don't exist in my old Xcode projects. As a result, when I build and run my old projects, I get weird warni开发者_如何学编程ngs that I didn't before.

I think it's just a matter of having the good factory defaults that come with new projects. Is there an easy way for me to migrate to the new project settings.

Right now, I'm having to create a new empty project, and move (almost one-by-one), all my files and groups over to the new one, and re-stitching everything together.

Use xcconfig files rather than the build pane. You can also build your own templates. Some of this has changed in Xcode 4, but most still applies.
