This is a copy of the official svn repo that you can find on google code: http://code.google.com/p/box2d/

The difference is that I modified it so the Xcode project compiles properly. You can use that to learn how to compile a Box2D has a static library and how to use it in an iOS project.

Open the Xcode project:

$ open Contributions/Platforms/iPhone/iPhoneTestbed.xcodeproj

Select the ALL_BUILD target and build.

To test in the simulator, choose the iPhoneTestBed target and Run the example, the dependencies will compile and the simulator will start.
