如何在 SwiftUI 中更改超链接文本颜色

Question

我正在尝试使用 SwiftUI 自定义更改给定 Markdown 字符串中超链接的默认字体颜色。相当于txtString.linkTextAttributes = [ .foregroundColor: UIColor.red ]UIKit 的东西。这是我的代码：

import SwiftUI

struct TextViewAttributedString: View {
    var markdownString: String
    var body: some View {
        Text(convertIntoAttributedString(markdownString:markdownString))
    }
    
    private func convertIntoAttributedString(markdownString: String) -> AttributedString {
        guard var attributedString = try? AttributedString(
            markdown: markdownString,
            options: AttributedString.MarkdownParsingOptions(allowsExtendedAttributes: true,
                                                             interpretedSyntax: .inlineOnlyPreservingWhitespace))
        else {
            return AttributedString(markdownString)
        }
        attributedString.font = .custom("Times New Roman", size: 16, relativeTo: .body)
        
        let runs = attributedString.runs
        for run in runs {
            let range = run.range
            if let textStyle = run .inlinePresentationIntent {
                if textStyle.contains(.stronglyEmphasized) { // .stronglyEmphasized is available
                    // change foreground color of bold text
                    attributedString[range].foregroundColor = .green
                }
                if textStyle.contains(.linkTextAttributes) { // compiler error since .linkTextAttributes not available
                    // change color here but .linkTextAttributes is not available in inlinePresentationIntent
                    // Any other way to change the hyperlink color?
                }
            }
        }
        return attributedString
    }
}

使用 AttributedString 的示例视图

import SwiftUI

struct AttributedStringView: View {
    let text: String = "**Bold** regular and _italic_ \nnewline\n[hyperlink](www.google.com)"
    var body: some View {
        TextViewAttributedString(markdownString: text)
    }
}

struct AttributedStringView_Previews: PreviewProvider {
    static var previews: some View {
        AttributedStringView()
    }
}

结果： 结果屏幕

Answer 1

对我来说最简单的解决方案是：

 Text(.init("some text **[google.com](https://google.com)**"))
     .accentColor(.red)
                                      

Answer 2

        if run.link != nil {
            // change foreground color of link
            attributedString[range].foregroundColor = .orange
        }
