scrollViewDidEndScrollingAnimation

When scrollViewDidEn开发者_开发技巧dScrollingAnimation is being called and in which cases would I need to use it?

From the documentation:

Discussion The scroll view calls this method at the end of its implementations of the UIScrollView and setContentOffset:animated: and scrollRectToVisible:animated: methods, but only if animations are requested.

Use it whenever you want to know about the scroll view animation ending.
