XCode 4: Easy way to convert Mac project to iOS?

I have a huge Mac project in XCode. I want to "convert" it, or add a build target for the iphone as well. Now my problem is that my project has approximately 200 files, and there are 192 compile sources (can be seen in the bui开发者_开发知识库ld phases tab) - So adding these 192 compile sources to the iphone build target is a hard task. Is there any easy "automated" way to do it?

I don't think you can do this, there is certainly no option in XCode 4 to do this.

You will probably run in to a lot of errors, since UIKit is different to AppKit. There are some classes that both have, but Cocoa Touch is missing a lot and introduce some new classes.
