Fixed : When a side drawer is open, it should also be refreshed in addition to center drawer #225

Fixed : When a side drawer is open, it should also be refreshed in addition to center drawer #225. Here is the fix. When MMDrawerController gets shown i.e. viewWillAppear is called at this time I am checking whether any of side drawers are open?. If a side drawer is open then I am refreshing that view using - (void)beginAppearanceTransition:(BOOL)isAppearing animated:(BOOL)animated on that view controller.
