Can WKWebView instance show webpage while it is loading?

Question

I'm using WKWebView to browse the specific website. WKWebView instance loads initial page of the website by URL with method load(_ request: URLRequest) -> WKNavigation? Until load request isn't completed I see white screen. Can WKWebView show already loaded parts of the webpage while the rest of the webpage is loading? Can UIWebView do this trick?

Answer 1

if white screen is your issue, i recommend you to display an custom progress indicator over the webView or some Animation view over your webView.

Once the loading is completed hide the progress indicator.

Start your Animation at:

 optional func webView(_ webView: WKWebView, 
    didStartProvisionalNavigation navigation: WKNavigation!)
{
//Start Progress indicator animation
}

End/Hide your Animation/Progress View at:

    optional func webView(_ webView: WKWebView, 
                didFinish navigation: WKNavigation!)
{
      //Stop Progress indicator animation
}
