SwiftUI WebKit WKWebView：如何支持多url

Question

我开发了一个网站，现在想开发 iOS 应用程序。

我的想法是：通过菜单更改新 url

struct ContentView: View {
    var body: some View {
        Webview(url: "https://readmorejoy.com")
        HStack {
            Menu("Menu") {
                Button("menu1", action: {
//                    Webview(url: "https://readmorejoy.com")
                })
                Button("menu2", action: {})
                Button("menu3", action: {})
            }
        }
    }
}

Answer 1

在这里

struct ContentView: View {
    @State private var urlString = "https://readmorejoy.com"   // << initial !!

    var body: some View {
        Webview(url: urlString)     // << use !!
        HStack {
            Menu("Menu") {
                Button("menu1", action: {
                    self.urlString = "https://readmorejoy.com"   // << update !!
                })
                Button("menu2", action: {})
                Button("menu3", action: {})
            }
        }
    }
}

好吧好吧这是我的更新代码

struct Webview: UIViewRepresentable {
    var url: String
    func makeUIView(context: Context) -> WKWebView {
        guard let url = URL(string: self.url) else {
            return WKWebView()
        }
        
        let request = URLRequest(url: url)
        let wkWebview = WKWebView()
        wkWebview.load(request)
        
        return wkWebview
    }
    
    func updateUIView(_ uiView: Webview.UIViewType, context: UIViewRepresentableContext<Webview>) {
        if let url = URL(string: self.url) {
            let request = URLRequest(url: url)
            uiView.load(request)
        }
    }
}
