[textView flashScrollIndicators];

UITextView is a subclass of UIScrollView. So there is a method flashScrollIndicators that you can call to prompts the user that the view is scrollable. It only flashes once for few seconds where user comes to a page that contains UIScrollView or its subclass. You may set timer to call this method more than one time.
