Flash scroll indicators when scrolling up

When I click the scroll bar at the top of the UIScrollView, the scroll indicators appear when they scroll and then disappear after they stop.

When I programmatically scroll up using [scrollView setContentOffset:CGPointZero animated:YES] , the scroll indicators disappear when scrolling up.

Is there any way to programmatically create a similar behavior for what happens when a user enters a status bar?
