xcode swift UIWebview 禁止打开以 https://m 开头的链接

Question

大家好，我最初加载的是 https://www.etcccc link but its a video and it has an overlay image that if clicked it will navigate to a https://m.etccccc，我只需要将以 "m" 而非 "www" 开头的网址限制为 return 错误在 shouldstartloadrequest 但我有问题。感谢所有帮助

Answer 1

webview 委托 shouldStartLoadWith 请求是限制 url.try this

的最佳位置

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {

        if request.url?.host?.hasPrefix("m") == true{
         return false
        }
        else{
         return true
        }
  }
