WKWebView should have a method to send messages from native to JS

WKWebView supports "- addScriptMessageHandler:name:" on the WKUserContentController which allows creating a communication channel that allows sending messages from JS to the native side.

As far as I can tell, there's no method for doing the reverse: sending messages from native to JS. This would be useful for causing navigations or other changes in a web page in response to pressing a native button (for instance).

(See also http://stackoverflow.com/q/24049343/49485.)

WKWebViewPrivate has _runJavaScriptInMainFrame: which sounds like it provides the appropriate function, but it isn't documented or supported. Can this method be publicized or a similar one added?

Thanks.

Fixed in iOS 8 beta 3

Not in docs, but in the public header: evaluateJavaScript:completionHandler:
