webview in core animation layer

问题:

I wanted to create a webView inside of a CALayer. Maybe it is too trivial but I am just getting my head into CA. Would anyone please be able to help?

cheers Ron

回答1:

Views can contain layers, Views can contain other views, and layers can contain layers. But layers cannot contain views.

If you want to animate a WebView, your best bet would be to embed it in an NSView where you've called setWantsLayer:YES and then animating the WebView's layer.

I don't think this works because webview doesn't seem to like core animation enabled in any view containing it. I'd simply like to get a drop shadow or blur effect on the screen behind my webview and I've tried enabling it in the parent or even in a view behind the webview... but nothing seems to work. I may be doing something wrong though.
