Flash scroll indicators while scrolling to the top

When I tap the status bar to the scroll to the top of a UIScrollView, the scroll indicators appear as it scrolls and then disappear once it stops.

When I programmatically scroll to the top using [scrollView setContentOffset:CGPointZero animated:YES], the scroll indicators disappear as it scrolls to the top.

Is there any way to programmatically produce similar behavior to what happens when the user taps on the status bar?
