If willDecelerate
of scrollViewDidEndDragging:willDecelerate:
is YES
, then yes, that's expected. You get scrollViewDidEndDragging
when the user lets go of the drag, but dragging
doesn't change until the visual scrolling/decelerating is done. Thus, when you let go of a drag, you may see scrollViewDidEndDragging
followed by some scrollViewDidScroll
(and dragging
still YES
).
Alternatively, you can check out tracking
, which turns to NO
as soon as the user lets go (even though the scroll view may still be scrolling).
