I'm using a UICollectionView
to scroll through a set of thumbnails quickly. Once scrolling ends, I'd like to display a larger hi-res version of the current thumbnail.
How can I detect when the user has completed scrolling? I do implement didEndDisplayingCell
, but that only tells me when a particular cell has scrolled off; it doesn't tell me when the scroll motion actually completes.
NS_CLASS_AVAILABLE_IOS(6_0) @interface UICollectionView : UIScrollView
UICollectionView
is a subclass of UIScrollView
. So if you have set the delegate and implemented UIScrollViewDelegate
, you should be able to detect this the same way as UIScrollView
.
For eg:-
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;
As per documentation, the above method should tell when the scroll view has ended decelerating the scrolling movement.
