在SwiftUI中不应将VStack中的文本截断 [英] Text inside a VStack truncates when it's not supposed to in SwiftUI

问题描述

我正在尝试在VStack内创建一个简单的Text堆栈，无论我做什么，即使我显式设置了lineLimit(nil)，文本也会被截断而不是自动换行(尽管我知道这一点)现在是默认设置.

I'm trying to create a simple stack of Text inside a VStack, and no matter what I do, the text will truncate instead of wrap, even if I explicitly set lineLimit(nil) (although I know this is the default now).

我已经尝试在VStack的第一个元素上设置layoutPriority(1)，并且我还尝试了其他一些帖子所建议的设置frame(idealHeight: .greatestFiniteMagnitude)，但似乎没有任何解决方法.

I've tried setting layoutPriority(1) on the first element in the VStack, and I have also tried setting frame(idealHeight: .greatestFiniteMagnitude) as some other posts have suggested, but nothing seems to fix the issue.

以下是重现此问题的一些代码:

Here is some code that reproduces the issue:

import SwiftUI

struct BugRepro: View {

    @State var length: Double = 1.0

    var body: some View {
        VStack {
            ForEach(0..<3) { i in
                BugReproElement(index: i)
            }
            .background(Color.gray3)
            .frame(width: UIScreen.main.bounds.width * CGFloat(length))


            Slider(value: $length, in: 0.0...1.0)
        }

    }
}

struct BugRepro_Previews: PreviewProvider {
    static var previews: some View {
        BugRepro()
    }
}

struct BugReproElement: View {
    var index: Int

    var body: some View {
        Text("iaush isuh siudh siudh isudh isudhdsiu sdiuh sdihs")
        .foregroundColor(.gray7)
        .frame(minWidth: 0, maxWidth: .infinity, alignment: .leading)
    }
}

这可能只是Xcode中的错误吗?我正在运行Beta 7

Could this just be a bug in Xcode? I'm running Beta 7

推荐答案

我想出了如何使文本正确呈现的方法.

I figured out how to get the text to render properly.

在此处应用答案有效:由SwiftUI VStack和列表中的其他视图压缩的视图

Applying the answer here works: Views compressed by other views in SwiftUI VStack and List

关键是要确保在.frame()

不需要Spacer()！
