URL not opening iOS webview custom renderer Xamarin forms

Question

Hi

I am facing an issue on the WebView URL renderer on iOS after the render page displays blank and the same page will be visible on Android devices. On Url getting some console error like some images not working.

Below function is deprecated on iOS version or change method means if page not working or not renderer then how to display message in place of blank page.

webViewWebContentProcessDidTerminate

below the iOS custom view renderer.

[assembly: ExportRenderer(typeof(CustomWebView), typeof(CustomWebViewRenderer))]
namespace Yuro.iOS.Controls
{
    /// <summary>
    /// CustomWebViewRenderer
    /// </summary>
    public class CustomWebViewRenderer : ViewRenderer<CustomWebView, WKWebView>
    {
        /// <summary>
        /// _wkWebView
        /// </summary>
        WKWebView _wkWebView;

        /// <summary>
        /// OnElementChanged
        /// </summary>
        /// <param name="e"></param>
        protected override void OnElementChanged(ElementChangedEventArgs<CustomWebView> e)
        {
            try
            {
                base.OnElementChanged(e);

                if (Control == null)
                {
                    var config = new WKWebViewConfiguration();
                    config.AllowsInlineMediaPlayback = true;
                    config.MediaPlaybackRequiresUserAction = false;
                    _wkWebView = new WKWebView(Frame, config);
                    SetNativeControl(_wkWebView);
                }
                if (e.NewElement != null)
                {
                    Control.LoadRequest(new NSUrlRequest(new NSUrl(Element.Url)));
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
    }
}

Hello,

This issue is caused by the server side. The picture links are not responding. You can refer to the above link to enable Web Inspector and debug this webview via Safari, then adjust the content on server side.

Best Regards,
