问题描述

如果我有 UIScrollView 并将其移动到特定位置，是否有任何方法可以获得它已移动的位置？

If I have a UIScrollView and move it around to a specific location, is there any way to get that position it has moved too?

推荐答案

检查UIScrollView的contentOffset属性：

Check UIScrollView's contentOffset property:

contentOffset - 内容视图的来源为
偏离滚动
视图的原点的点。

contentOffset - The point at which the origin of the content view is offset from the origin of the scroll view.

通过实现和设置UIScrollView的委托，您还可以在UIScrollView中处理大量滚动/缩放事件。

By implementing and setting UIScrollView's delegate you can also handle numerous scrolling/zooming events in UIScrollView.
