ios - 以编程方式添加 WKWebView

Question

我是iOS开发的新手，一直在用代码添加WKWebview时遇到困难。我也打算让它全宽，但我得到一个空屏幕。

var webView = WKWebView()
var activityIndicatorView: ActivityIndicatorView!

override func viewDidLoad() {
    super.viewDidLoad() 
     //show Activity Indicator
    self.activityIndicatorView = ActivityIndicatorView(title: "Loading content...", center: self.view.center)
    self.activityIndicatorView.startAnimating();
    self.view.addSubview(self.activityIndicatorView.getViewActivityIndicator())self.view.addSubview(self.activityIndicatorView.getViewActivityIndicator())
    // Do any additional setup after loading the view.
    let urlString = "http://www.youtube.com";
    let request = URLRequest(url:URL(string: urlString)!)
    self.webView.load(request)
     self.view = webView
}

Answer 1

let webview = WKWebView()
    webview.frame  = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 100)
    webview.load(URLRequest(url: Bundle.main.url(forResource: "index", withExtension:"html", subdirectory: "subdirectories")! as URL) as URLRequest)
    self.view.addSubview(webview)
