How to know exactly when a UIScrollView's scrolling has stopped?

Question

In short, I need to know exactly when the scrollview stopped scrolling. By \'stopped scrolling\', I mean the moment at which it is no longer moving and not being touched.

Answer 1

I found a solution:

-(void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate

I did not notice that last bit before, willDecelerate. It is false when the scrollView is stationary when ending the touch. Combined with the above-mentioned speed check, I can snap both when it's slow (and not being touched) or when it's stationary.

For anyone not doing any snapping but needs to know when scrolling stopped, didEndDecelerating will be called at the end of the scroll movement. Combined with a check on willDecelerate in didEndDragging, you'll know when the scrolling has stopped.
