swiftui间距不符合预期

Question

我的代码如下：

import SwiftUI


struct DotView: View {
    var body: some View {
        GeometryReader { geo in
            let width = geo.size.width
            VStack() {
                Circle()
                    .frame(width: width, height: width)
                Spacer()
                Circle()
                    .frame(width: width, height: width)
            }
        }
    }
}

struct TestView: View {
    var body: some View {
        GeometryReader { geo in
            VStack() {
                HStack() {
                    Text("11")
                    DotView()
                        .frame(width: 8, height: 23, alignment: .center)
                    Text("22")
                }
                .font(.system(size: 48))
                .background(Color.gray)
                HStack() {
                    Text("123456789")
                }
                .font(.system(size: 30))
                .background(Color.gray)
            }
            .frame(width: geo.size.width, height: geo.size.height)
            .background(Color.blue)
        }
    }
    
}

struct TestView_Previews: PreviewProvider {
    static var previews: some View {
        TestView()
            .frame(width: 200, height: 200, alignment: .center)
            .cornerRadius(23.0)
    }
}

视图如下图，"11:22"和"123456789"之间有一个空格

但是，当我将视图 DotView 评论为以下代码时：

struct TestView: View {
    var body: some View {
        GeometryReader { geo in
            VStack() {
                HStack() {
                    Text("11")
//                    DotView()
//                        .frame(width: 8, height: 23, alignment: .center)
                    Text("22")
                }
                .font(.system(size: 48))
                .background(Color.gray)
                HStack() {
                    Text("123456789")
                }
                .font(.system(size: 30))
                .background(Color.gray)
            }
            .frame(width: geo.size.width, height: geo.size.height)
            .background(Color.blue)
        }
    }
}

间距消失。为什么这个DotView会影响间距？

Answer 1

您可以在 TestView 中将“(spacing: 0)”添加到 VStack

VStack(间距: 0)

swiftui间距不符合预期

swiftui spacing is not in line with expectations
