SwiftUI中如何实现NavigationLink与Text View内联显示？

方案一：SwiftUI原生AttributedString + 导航路径控制 #

这种方案相对简便，利用AttributedString给指定文本添加链接标记，通过监听URL打开事件触发导航跳转，自动处理文本流式排版。

import SwiftUI

struct ContentView: View {
    @State private var navigationPath = NavigationPath()
    
    var body: some View {
        NavigationStack(path: $navigationPath) {
            VStack {
                Text(createAttributedText())
                    .onOpenURL { url in
                        if url.scheme == "app" && url.host == "targetpage" {
                            navigationPath.append("Target")
                        }
                    }
            }
            .navigationDestination(for: String.self) { destination in
                if destination == "Target" {
                    TargetView()
                }
            }
        }
    }
    
    private func createAttributedText() -> AttributedString {
        var baseText = AttributedString("这是一段较长的文本，其中需要将")
        var linkSegment = AttributedString("加粗的文本部分")
        linkSegment.link = URL(string: "app://targetpage")
        linkSegment.font = .bold(Font.body)
        baseText.append(linkSegment)
        baseText.append(AttributedString("设置为可跳转的链接，剩余文本会自动换行，保持流式排版效果，不需要手动处理布局问题。"))
        return baseText
    }
}

struct TargetView: View {
    var body: some View {
        Text("目标页面")
            .navigationTitle("跳转成功")
    }
}

方案二：UIKit UITextView包装（灵活度更高） #

如果需要自定义链接样式、点击反馈等精细控制，可以用UITextView包装成SwiftUI视图，通过代理处理点击事件。

import SwiftUI
import UIKit

struct LinkedTextView: UIViewRepresentable {
    let attributedText: NSAttributedString
    let onLinkTap: (URL) -> Void
    
    func makeUIView(context: Context) -> UITextView {
        let textView = UITextView()
        textView.attributedText = attributedText
        textView.isEditable = false
        textView.isSelectable = true
        textView.dataDetectorTypes = .link
        textView.delegate = context.coordinator
        textView.backgroundColor = .clear
        return textView
    }
    
    func updateUIView(_ uiView: UITextView, context: Context) {
        uiView.attributedText = attributedText
    }
    
    func makeCoordinator() -> Coordinator {
        Coordinator(onLinkTap: onLinkTap)
    }
    
    class Coordinator: NSObject, UITextViewDelegate {
        let onLinkTap: (URL) -> Void
        
        init(onLinkTap: @escaping (URL) -> Void) {
            self.onLinkTap = onLinkTap
        }
        
        func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
            onLinkTap(URL)
            return false
        }
    }
}

// 使用示例
struct ContentView: View {
    @State private var navigationPath = NavigationPath()
    
    var body: some View {
        NavigationStack(path: $navigationPath) {
            VStack {
                LinkedTextView(attributedText: createNSAttributedText()) { url in
                    if url.scheme == "app" && url.host == "targetpage" {
                        navigationPath.append("Target")
                    }
                }
            }
            .navigationDestination(for: String.self) { destination in
                TargetView()
            }
        }
    }
    
    private func createNSAttributedText() -> NSAttributedString {
        let baseString = NSMutableAttributedString(string: "这是一段较长的文本，其中需要将")
        let linkString = NSAttributedString(
            string: "加粗的文本部分",
            attributes: [
                .link: URL(string: "app://targetpage")!,
                .font: UIFont.boldSystemFont(ofSize: UIFont.systemFontSize)
            ]
        )
        baseString.append(linkString)
        baseString.append(NSAttributedString(string: "设置为可跳转的链接，剩余文本会自动换行，保持流式排版效果，不需要手动处理布局问题。"))
        return baseString
    }
}
