强制uiscrollview即使单个项目也可以反弹滚动 [英] Force uiscrollview to bounce scrolling even with a single item

问题描述

我有一个UIScrollView，其中包含不同数量的项目/子视图.如果有多个项目，则滚动弹跳有效.但是，有时滚动视图只应包含一个项目，我想向用户提供反馈，告知他们的滚动已被识别-从而产生反弹效果.但是，UIScrollView禁用仅滚动一项.

I have a UIScrollView with varying numbers of items/subviews. When there is more than one item, scrolling bounce works. However, there are times when the scrollview should only have one item, and I would like to provide the feedback to the user that their scrolls are being recognized--thus the bounce effect. However, UIScrollView disables scrolling with just one item.

推荐答案

答案:将alwaysBounceHorizo​​ntal或alwaysBounceVertical设置为true.在撰写本文时，我回答了自己的问题，并认为我不妨将其发布以帮助他人.

Answer: set alwaysBounceHorizontal or alwaysBounceVertical to true. I answered my own question while writing this up and figured I might as well post it to help others.
