MY app is for iPad using Storyboards with two scenes. On one scene, I have a UIScrollView that contains a UIVIew. It scrolls, but bounces back immediately, rendering itself useless. The size of the UIScrollView is 768x590; the size of the UIView is 768x1590; ContentSize of the UIScrollView is 768x590. This is an image of the UIScrollView settings:

(过去 6 个小时我一直在查看 SO 和 Google，尝试了很多东西，但没有任何效果.我也做过几次 CMD + Option + K(Clean)，但这也没有帮助.

(I have looked at SO and Google for the past 6 hours, tried a lot of stuff, but nothing works. I have also done a CMD + Option + K (Clean) several times, and that didn't help either.

为什么它不能正确滚动?

Why does it not scroll properly?

推荐答案

找到适合我的方法！

当你在 InterfaceBuilder 中将视图嵌入到 UIScrollView 中时，然后有一个自动设置的约束.如果您的视图长"于纵向屏幕，它根本不会滚动.

When you embed a view into a UIScrollView in InterfaceBuilder, then there's a constraint automatically set. If your view is "longer" than the screen in portrait, it wont scroll at all.

但是如果你旋转屏幕，你会注意到滚动一个很少.

But if you rotate the screen, you'll notice the ability to scroll a little.

要让 UIScrollView 在 AutoLayout 中运行，请查看您的约束.

To get UIScrollView going in AutoLayout look into your constraints.

找到垂直空间-滚动视图-视图"并从常量"中设置到自动" - 为我修复了一切.

Find "Vertical Space - Scroll View - View" and set it from "constant" to "auto" - fixed everything for me.

感谢您的帮助...我很感激.
