I have a previous project thats using Facebook SDK 3.0 (for iOS 5). and I just updated my xcode to 4.5 (iOS6) and compiler is giving me linker errors. so I delete the facebook (3.0) and add 3.1 but still dont work. does anyone have clue how to fix it?
thanks so much!!
You probably forgot to add the new Frameworks. Try going through this guide:
