How do I use a relative path in Xcode project settings?
All paths in Build Settings are assumed relative to the directory that contains the .xcodeproj file. Use the standard Unix path tokens
. project directory.. parent directorySo if your project file is trunk/Mac/proj.xcodeproj, and your headers are in trunk/Headers/foo.h, you would add ../Headers to your Header Search Paths.
In the upper left corner next to the build/stop buttons, click on the name of your project and Edit Scheme...
In the left column, click on Run
Click on Options
Put a check next to Working Directory: Use custom working directory.
You can then change the relative path to anywhere you want.
EDIT: This is for Xcode 4.1
