類型“SwiftUIWebView”不符合協議“NSViewRepresentable”

Question

我正在關注本教程，了解如何在 SwiftUI 中創建 WebView，除了我正在為 macOS 應用程序而不是 IOS 制作它。

我將 UIViewRepresentable 切換為 NSViewRepresentable 並收到此錯誤： Type 'SwiftUIWebView' does not conform to protocol'NSViewRepresentable'

import SwiftUI
import WebKit
import AppKit


struct SwiftUIWebView: NSViewRepresentable {
    let url: URL?
    
    func makeUIView(context: Context) -> WKWebView {
        let prefs = WKWebpagePreferences()
        prefs.allowsContentJavaScript = true
        let config = WKWebViewConfiguration()
        config.defaultWebpagePreferences = prefs
        let webView = WKWebView(frame: .zero, configuration: config)
        
    }
    
    
    func updateUIView(_ uiView: WKWebView, context: Context) {
        guard let myURL = url else {
            return
        }
        let request = URLRequest(url: myURL)
        uiView.load(request)
        
    }
}

Answer 1

您還需要使用makeNSView協議委托而不是makeUIView 。

struct SwiftUIWebView: NSViewRepresentable {
    let url: URL?
    
    func makeNSView(context: Context) -> WKWebView {
        let prefs = WKWebpagePreferences()
        prefs.allowsContentJavaScript = true
        let config = WKWebViewConfiguration()
        config.defaultWebpagePreferences = prefs
        let webView = WKWebView(frame: .zero, configuration: config)
        return webView
    }
    func updateNSView(_ nsView: WKWebView, context: Context) {
        guard let myURL = url else {
            return
        }
        let request = URLRequest(url: myURL)
        nsView.load(request)
    }
}

請查看文檔

方法是makeNSView和updateNSView 。
