UIScroll View Delegate not calling ScrollViewDidEndScrollingAnimation

Question

I have implemented the UIScrollViewDelegate protocol in my .h file and i have implemented the

- (void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView

method in my .m class. when the scrolling is done in my table view other delegate method of scrollview are getting called, but when scrolling ends, -scrollViewDidEndScrollingAnimation: is not getting called. I am bit stuck in this.

Thanks and regards

-scrollViewDidEndScrollingAnimation: is called when a programmatic-generated scroll finishes.
-scrollViewDidEndDecelerating: is called when a user-swipe scroll finishes.

+1 and thank you for explaining the difference between the two delegate methods. I think this should be the accepted answer! – e.James Feb 08 '11 at 06:42

And if you also want to react on when a user drags the scroll view, but releases it without the scroll view scrolling further, you should also implement the ``scrollViewDidEndDragging`` method, you can check the bool parameter ``willDecelerate`` to decide on whether you have to execute the code here or in the ``scrollViewDidEndDecelerating`` method. – TheEye Dec 10 '13 at 15:03

I had the same problem ... Try using scrollViewDidEndDecelerating instead.

Had the same problem. Have used the following in my delegate class:

#pragma mark -
#pragma mark UIScrollViewDelegate
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {

    NSLog(@"lol");
}

works like a charm!

I had the same problem and the issue was i did not include the delegate code:

self.myScrollView.delegate=self;

Hope this helps someone as well.
