ios - 当我单击 WKWebView 浏览器中的链接时，它会转到 safari

Question

我如何让我的 WKWebview 浏览器在同一浏览器中打开链接，目前，如果我单击链接，它不会执行任何操作，只允许我在 Safari 中打开它。我怎样才能解决这个问题，以便当单击链接时它会在同一个 WkWebView 浏览器中打开？

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {

    @IBOutlet weak var webView: WKWebView!

    //Web View
    override func viewDidLoad() {
        super.viewDidLoad()

        let url = URL(string: "http://tweetdeck.twitter.com/")
        let request = URLRequest(url: url!)

        webView.load(request)
        webView.navigationDelegate = self

    }

请使用 WKNavigationDelegate 的decidePolicyFor方法尝试此代码

extension ViewController: WKNavigationDelegate {
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    if navigationAction.navigationType == .linkActivated {
        guard let url = navigationAction.request.url else {
            decisionHandler(.allow)
            return
        }

        let components = URLComponents(url: url, resolvingAgainstBaseURL: false)
        if components?.scheme == "http" || components?.scheme == "https"
        {
            UIApplication.shared.open(url)
            decisionHandler(.cancel)
        } else {
            decisionHandler(.allow)
        }
    } else {
        decisionHandler(.allow)
    }
}}
