Can ARKit display WKWebview?

问题

Tried ARKit to show WKWebView and all I got is a page that shows background but no foreground. The page can be scrolled though. I attached Apple web page as screenshot.

Here's the code:

DispatchQueue.main.async {
  let webView = WKWebView(frame: CGRect(x: 0, y: 0, width: 640, height: 480))
  let request = URLRequest(url: URL(string: "https://www.apple.com")!)

  webView.load(request)
  plane.firstMaterial?.diffuse.contents = webView
}

Does that mean ARKit cannot display web page? I am using iOS 12 beta 2 running ARKit 2. I have also switch off App Transport Security Settings and allow arbitrary load.

I also look through this site and found someone with the same issue but no solution: WKWebView is showing only background

Update: It works for UIWebView.

回答1:

The documentation explicity states that you can't display UIViews as a SCNMaterialProperty:

SceneKit cannot use a layer that is already being displayed elsewhere (for example, the backing layer of a UIView object).

One workaround would be to create an UIImage of the page and present that.

回答2:

It would be difficult to implement it using Scenekit Nodes, but would be working if you use SprikeKit Nodes. Use SpriteKit nodes for this.
