Swiftui Text Markdown 动态字符串不起作用 [英] Swiftui Text Markdown dynamic string not working

问题描述

我想动态投递内容，显示超链接，但是不能动态投递，不起作用

I want to dynamically deliver content and display hyperlinks, but it can’t be delivered dynamically and doesn’t work

let linkTitle = "Apple Link"
let linkURL = "http://www.apple.com"
let string = "[Apple Link](http://www.apple.com)"
            
Text(string)        // Not working

Text("[Apple Link](http://www.apple.com)")  // Working
            
Text("[\(linkTitle)](http://www.apple.com)")    // Working
            
Text("[\(linkTitle)](\(linkURL))")  // Not working
            

推荐答案

你可以试试这个取自:如何在 SwiftUI 文本中显示 HTML 或 Markdown? 页面中间.

you can try this taken from: How to show HTML or Markdown in a SwiftUI Text? halfway down the page.

extension String {
    func markdownToAttributed() -> AttributedString {
        do {
            return try AttributedString(markdown: self) /// convert to AttributedString
        } catch {
            return AttributedString("Error parsing markdown: \(error)")
        }
    }
}
struct ContentView: View {
    let linkTitle = "Apple Link"
    let linkURL = "https://www.apple.com"
    let string = "[Apple Link](https://www.apple.com)"
       
    @State var textWithMarkdown = "[Apple Link](https://www.apple.com)"
    
    var body: some View {
        VStack {

            Text(textWithMarkdown.markdownToAttributed()) // <-- this works
            
            Text(string)        // Not working

            Text("[Apple Link](http://www.apple.com)")  // Working
                        
            Text("[\(linkTitle)](http://www.apple.com)")    // Working
                        
            Text("[\(linkTitle)](\(linkURL))")  // Not working
        }

    }
}
