SwiftUI:组合自定义文本

这是的自定义功能 Text 然而,你可以模仿一些行为。请参见以下示例:

import SwiftUI

struct MyText: View {
    
    private let configurations: [Configuration]
    
    init(_ title: String, foregroundColor: Color = .black) {
        self.configurations = [
            .init(title: title,
                  foregroundColor: foregroundColor)
        ]
    }
    
    private init(configurations: [Configuration]) {
        self.configurations = configurations
    }
    
    private struct Configuration: Identifiable {
        let id = UUID()
        let title: String
        let foregroundColor: Color
    }
    
    var body: some View {
        HStack {
            ForEach(configurations, content: Render.init)
        }
    }

    static func + (lhs: Self, rhs: Self) -> Self {
        let configurations = lhs.configurations + rhs.configurations
        return MyText(configurations: configurations)
    }
    
    private struct Render: View {
        let configuration: Configuration
        var body: some View {
            Text(configuration.title)
                .foregroundColor(configuration.foregroundColor)
        }
    }
}

struct MyText_Previews: PreviewProvider {
    static var previews: some View {
        MyText("hej") + MyText("Yo", foregroundColor: .red)
    }
}

然而,这更多的是一种概念证明,而不是一种实践建议。
