问题描述

如果我有一个 UIScrollView 并将其移动到特定位置,有没有办法让它也移动到那个位置?

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

查看UIScrollView的contentOffset属性:

Check UIScrollView's contentOffset property:

contentOffset - 内容视图的原点从滚动的原点偏移查看.

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,您还可以处理 UIScrollView 中的大量滚动/缩放事件.

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