let frame = CGRect(x: 0, y: 0, width: UIScreen.w, height: UIScreen.h)
let webView = WKWebView(frame: frame)
webView.navigationDelegate = self
webView.uiDelegate = self

2、加载上述H5链接

guard let url = URL(string: urlString) else {return}
let request = URLRequest(url: url)
webView.load(request)
view.addSubview(webView)

3、使用代理拦截
1、首先遵守协议WKNavigationDelegate,WKUIDelegate
2、点击H5上面的iOS下载按钮时,会把按钮下载链接传到下面的代理方法,进行拦截处理就好了
