带包装的SwiftUI HStack [英] SwiftUI HStack with Wrap

问题描述

蓝色标记(当前被截断)是否有可能完全显示，然后自动换行?

Is it possible that the blue tags (which are currently truncated) are displayed completely and then it automatically makes a line break?

NavigationLink(destination: GameListView()) {
                            VStack(alignment: .leading, spacing: 5){
                                // Name der Sammlung:
                                Text(collection.name)
                                    .font(.headline)
                                // Optional: Für welche Konsolen bzw. Plattformen:
                                HStack(alignment: .top, spacing: 10){
                                    ForEach(collection.platforms, id: \.self) { platform in
                                        Text(platform)
                                            .padding(.all, 5)
                                            .font(.caption)
                                            .background(Color.blue)
                                            .foregroundColor(Color.white)
                                            .cornerRadius(5)
                                            .lineLimit(1)
                                    }
                                }
                            }
                            .padding(.vertical, 10)
                        }

此外，蓝色标记中不应包含换行符:

Also, there should be no line breaks with in the blue tags:

这应该是最后的样子:

That's how it should look in the end:

推荐答案

以下是一些使用alignmentGuide如何完成此操作的方法.简化它是为了避免过多的代码发布，但希望它是有用的.

Here is some approach of how this could be done using alignmentGuide(s). It is simplified to avoid many code post, but hope it is useful.

更新:还更新了&我对具有自动换行和动态高度的SwiftUI HStack的回答中，以下解决方案得到了改进:

Update: There is also updated & improved variant of below solution in my answer for SwiftUI HStack with wrap and dynamic height

这是结果:

这是完整的演示代码(自动支持方向):

And here is full demo code (orientation is supported automatically):

import SwiftUI

struct TestWrappedLayout: View {
    @State var platforms = ["Ninetendo", "XBox", "PlayStation", "PlayStation 2", "PlayStation 3", "PlayStation 4"]

    var body: some View {
        GeometryReader { geometry in
            self.generateContent(in: geometry)
        }
    }

    private func generateContent(in g: GeometryProxy) -> some View {
        var width = CGFloat.zero
        var height = CGFloat.zero

        return ZStack(alignment: .topLeading) {
            ForEach(self.platforms, id: \.self) { platform in
                self.item(for: platform)
                    .padding([.horizontal, .vertical], 4)
                    .alignmentGuide(.leading, computeValue: { d in
                        if (abs(width - d.width) > g.size.width)
                        {
                            width = 0
                            height -= d.height
                        }
                        let result = width
                        if platform == self.platforms.last! {
                            width = 0 //last item
                        } else {
                            width -= d.width
                        }
                        return result
                    })
                    .alignmentGuide(.top, computeValue: {d in
                        let result = height
                        if platform == self.platforms.last! {
                            height = 0 // last item
                        }
                        return result
                    })
            }
        }
    }

    func item(for text: String) -> some View {
        Text(text)
            .padding(.all, 5)
            .font(.body)
            .background(Color.blue)
            .foregroundColor(Color.white)
            .cornerRadius(5)
    }
}

struct TestWrappedLayout_Previews: PreviewProvider {
    static var previews: some View {
        TestWrappedLayout()
    }
}
