Three20 Library Cannot find its own headers Xcode iPhone

#import "Three20/Three20.h"开发者_Go百科 Fails. Go download it and build a sample app. If that works, then make a new app from the templates provided, then watch as it fails spectacularly to find the right HEADER_SEARCH_PATH.

1) I've gone to the info page for the TARGET and not the PROJECT (Well, I tried both) and tried a bunch of different paths for the HEADER_SEARCH_PATH field.

2) I've tried dragging and dropping the dependent files from the finder and COPYING or just referencing both fails.

Read this. It is an article about the (very) recent three20 changes that you are having troubles with. Pay attention to the sections Imports and Migrating to the New Three20.
