Is there a correct way to know when a ScrollView has "Paged"?

[JasonR]

I'm working on an app roughly based on Apple's PageControl sample. In order to smooth it out, each time the ScrollView stops on the next page, I need to play some sounds and do other work. If the user goes slowly, it's easy, but when the user flips quickly, I can't tell when a page boundary is reached, even though I can see it visually.

Is there a correct way to do this? I've almost got a solution, but it feels a bit clunky.
