After User authorizes the App. Facebook request the browser to launch the app that requested access. That url is based on App's url schemes ( defined in App's plist). So you need to double check that. Safari shows error because it cannot find the url scheme -> Invalid URL

it is of the form like fb<myAppId>. After that do a clean build of project and run.
