我在 ScrollView 中创建了一个内容 View ，使用 UIScrollView 教程使用常见的自动布局添加了约束。但是当没有内容时如何阻止我的 Scrollview 向上滚动， View 向下滑动到内容，但我想禁用向上滚动，我搜索了答案但没有找到，请帮忙。
最佳答案
能够稍微滚动超出 UIScrollView 中的内容被称为“弹跳”。
The scroll view must know the size of the content view so it knows when to stop scrolling; by default, it “bounces” back when scrolling exceeds the bounds of the content.
您需要将反弹设置为否:
If the value of [bounces] is YES, the scroll view bounces when it encounters a boundary of the content. Bouncing visually indicates that scrolling has reached an edge of the content. If the value is NO, scrolling stops immediately at the content boundary without bouncing. The default value is YES
scrollView.bounces = NO;
