How to use AttributedString in SwiftUI. There is no API available to use AttributedString in Text

推荐答案

iOS 15 和 Swift 5.5

Text 现在支持 Markdown，您也可以创建自定义属性:

iOS 15 and Swift 5.5

Text now supports markdown and also you can create custom attributes:

您甚至可以远程获取定义的属性，例如:

You can even get defined attributes remotely like:

您可以将多个 Text 对象与一个简单的 + 运算符组合在一起，这将处理一些属性:

You can combine multiple Text objects together with a simple + operator and that will handle some of the attributions:

_{每个都可以有多个特定的修饰符}

由于它不直接支持 Text(直到 iOS 15)，您可以将 UILabel 放在那里并随意修改它:

Since it doesn't support directly on Text (till iOS 15), you can bring the UILabel there and modify it in anyway you like:

struct UIKLabel: UIViewRepresentable {

    typealias TheUIView = UILabel
    fileprivate var configuration = { (view: TheUIView) in }

    func makeUIView(context: UIViewRepresentableContext<Self>) -> TheUIView { TheUIView() }
    func updateUIView(_ uiView: TheUIView, context: UIViewRepresentableContext<Self>) {
        configuration(uiView)
    }
}

用法:

var body: some View {
    UIKLabel {
        $0.attributedText = NSAttributedString(string: "HelloWorld")
    }
}
