Hello John
Maybe with the delegate methods... they tell you when your scrollView
begins to scroll (-scrollViewWillBeginDragging:) and when it stops
scrolling (-scrollViewDidEndDecelerating:)... and there are other
methods that might be of interest... just have a look at the
UIScrollViewDelegate Protocol Reference!

Hello, all ...
After making the NSOperation and view tag changes, my app is scrolling
a large table view with hundreds of images much better. However, there
is still some jerkiness, caused by the fact that when the NSOperation
calls the refresh (image update) method, it has to call it on the main
thread. So, every time the image needs to update, the scrolling pauses
for a bit, which makes scrolling jerky when images haven't been cached.
I was thinking that I could only update the image if the table view
isn't scrolling, but I don't see an isScrolling property on
UIScrollView. Is there a way, in OS 2.2.1, that I can tell if a scroll
view is scrolling?
Regards,
John
