问题描述

如何测试滚动视图是否弹跳？反弹结束时是否有通知或其他内容？

How can I test if the scroll view is bouncing? Is there a notification or something when the bounce ends?

推荐答案

是...查看UIScrollViewDelegate规范，实现包括下面两个，并相应地设置你的UIScrollView的委托：

Yes... check out the UIScrollViewDelegate spec, implement the methods including the two below, and set your UIScrollView's delegate accordingly:

// User stops dragging the table view.

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView
    willDecelerate:(BOOL)decelerate;

// Control slows to a halt after the user drags it

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;

您可能对scrollViewDidEndDecelerating最感兴趣。这些也可以在我最初找到它们的UITableView中工作（UITableView继承自UIScrollView）。

You will probably be most interested in scrollViewDidEndDecelerating. These also work in UITableView which is where I originally found them (UITableView inherits from UIScrollView).
