推荐答案

希望以下内容会有所帮助.当然，您可以随意调整参数.

Hope the following will be helpful. Of course you can tune parameters as you wish.

演示:

方法代码:

import SwiftUI

struct FractionView: View {
    var numerator: String
    var denominator: String
    var body: some View {
        HStack {
            Text("\(numerator)")
                .offset(x: 4, y: 0)
                .alignmentGuide(VerticalAlignment.center,
                                computeValue: { d in d[.bottom] })
            Text("∕").font(.system(size: 32))
            Text("\(denominator)")
                .offset(x: -4, y: 0)
                .alignmentGuide(VerticalAlignment.center,
                                computeValue: { d in d[.top] })
        }
    }
}

struct TestFraction: View {
    var body: some View {
        VStack(spacing: 8) {
            FractionView(numerator: "1", denominator: "2")
            FractionView(numerator: "5", denominator: "7")
            FractionView(numerator: "11", denominator: "19")
            FractionView(numerator: "31", denominator: "9")
        }
    }
}

struct TestFraction_Previews: PreviewProvider {
    static var previews: some View {
        TestFraction()
    }
}
