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

Answer 1

-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! – Haslam

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. – Anagram

Answer 2

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!

Answer 4

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.

Swift?

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
