如何仅在ScrollView中禁用滚动而不在内容视图中禁用滚动? [英] How to only disable scroll in ScrollView but not content view?

问题描述

最近，我编写了一个小的SwiftUI库，该库可以旋转View数组并选择View.

Recently I wrote a small SwiftUI library that can rotate an array of Views and select view.

但是发现了一个问题，我无法弄清楚在正常模式下如何在ScrollView中禁用滚动.

But found an issue that I can't figure out how to disable scroll in ScrollView while in normal mode.

不幸的是，我试图将 .disabled(true)放在 ScrollView 的末尾，这不仅禁用了滚动功能，而且还禁用了ScrollView中的所有视图.

I tried to put .disabled(true) at the end of the ScrollView unfortunately, it not only disable scroll but also all the views in ScrollView.

此处是源代码的源代码https://github.com/raxabizze/RotateViewManager"rel =" noreferrer>项目.

Here's source code of the project.

我应该添加什么修饰符来解决这个问题?

What modifier should I add to solve this?

我试图更改滚动轴，但一旦滚动轴变为[]，scrollview将重置其内容偏移量，想知道是否有一种方法可以在不更改轴的情况下阻止滚动.

I have tried to change the scroll axis but once it becomes [], scrollview will reset its content offset, wondering if there's a way to block scrolling without changing the axis.

最后，我只添加了 DragGesture()来阻止滚动事件并正常工作.

At last, I just add a DragGesture() to block scroll event and works fine.

推荐答案

如果要滚动视图，则仅将 .horizo​​ntal 作为滚动轴.否则，传递空集.

Only pass .horizontal as the scroll axis if you want the view to scroll. Otherwise, pass the empty set.

struct TestView: View {
    @Binding var shouldScroll: Bool

    var body: some View {
        ScrollView(axes, showsIndicators: false) {
            Text("Your content here")
        }
    }

    private var axes: Axis.Set {
        return shouldScroll ? .horizontal : []
    }
}
