Android's addJavascriptInterface equivalent in iOS

Question

As you may know, Android's WebView has a method named addJavascriptInterface() which imports an Android JAVA object to Javascript context.

the question is, Is there any equivalent of it on iOS?

Answer 1

UIWebView on iOS doesn't have methods to add interface to DOM.
But you still can talk to your code from javascript assigning something to window.location and handling that request in webView:shouldStartLoadWithRequest:navigationType: delegate method.

Answer 2

I know this question is really old, but it seems that there is a better way to do it now with a WKWebView. See this answer: https://stackoverflow.com/a/37373745/1417922
