After upgrade XCode from 4.2 to 4.3 I\'ve got below problem. I can\'t build it. Do you guys have idea how can I resolve this problem? even some clue would be helpful to me.<
Using xcode 4.6 and trying to add facebook SDK 3.1 I had this problem because I didn't select to add the files to my test target.
You should check both targets when you copy the framework.
