WKWebViewIOSControlMBS.CreateWebView(URL as String, request as NSURLRequestMBS) as WKWebViewIOSControlMBS

If needed we can add configuration, windowFeatures and navigationAction parameters in future version.

Return a web viewer control or nil.

The web view returned must be created with the specified configuration. WebKit will load the request in the returned web view.

If you do not implement this method or return nil, the web view will cancel the navigation.

WKWebViewIOSControlMBS.decidePolicyForNavigationAction(navigationAction as WKNavigationActionMBS, decisionHandler as WKPolicyForNavigationActionDecisionHandlerMBS)

Please inspect navigationAction to find the information about what action happened.

You can show a dialog to ask user and once you know the decision call a method on decisionHandler object to report the decision.

If you want to open this in a new window/tab, please call decisionHandler.Cancel method here, take the URL and load it in the new WebView in the new window/tab.

Like the CancelClose event in Xojo, you can call decisionHandler.Cancel method to call it.

WKWebViewIOSControlMBS.decidePolicyForNavigationResponse(navigationResponse as WKNavigationResponseMBS, decisionHandler as WKPolicyForNavigationResponseDecisionHandlerMBS)

Sub decidePolicyForNavigationResponse(navigationResponse as WKNavigationResponseMBS, decisionHandler as WKPolicyForNavigationResponseDecisionHandlerMBS) Handles decidePolicyForNavigationResponse
  dim MimeType as string = navigationResponse.response.MIMEType
  
  if MimeType = "application/zip" or _
      MimeType = "application/x-tar" or _
      MimeType = "application/octet-stream" then
    // we download archive files
    decisionHandler.Download
  else
    // allow normal website to load
    decisionHandler.Allow
    
  end if
End Sub

navigationResponse: Descriptive information about the navigation response.

You can show a dialog to ask user and once you know the decision call a method on decisionHandler object to report the decision.
