Sample implementation for a PhoneGap FB Plugin that hook up necessary events from regular Facebook JS SDK so it override behavior for Auth and UI.

PhoneGap FB Connect hooks

FB.Event.subscribe('FB.init.start', 
  function(options) {
    if (options.nativeInterface) {
      FB._nativeInterface = options.nativeInterface;
      FB._nativeInterface.init(FB._apiKey);
    }
  });

FB.Event.subscribe('FB.auth.staticAuthCheck.start', 
  function(eventProps) {
   // cancel default static auth check
   eventProps.returnValue = false;
});


FB.Event.subscribe('FB.ui.start', 
  function(eventProps, params, cb) {
    if (!FB._nativeInterface) {
      return;
    }
    switch (params.method) {
        case 'permissions.request':
          FB._nativeInterface.login(cb, params);
          break;
        case 'permissions.oauth':
          FB._nativeInterface.login(cb, params);
          break;
        case 'auth.logout':
          FB._nativeInterface.logout(cb);
          break;
        case 'auth.status':
          FB._nativeInterface.getLoginStatus(cb);
          break;
     }
     // Stop default handling
     eventProps.returnValue = false;
   }
 });
