Unity.call overrides previous Unity.call

[whimsica]

In javascript:

Unity.call("message1");
Unity.call("message2);

only message2 is processed.
How can I get both messages to be processed?

I'm using mac editor and wkwebkit

I've modified the definition of Unity.call() in #149 (comment) . The new definition solves the issue discussed but it has the side effect you described. If the following original definition based on iframe works well for you, please utilize it:

                webViewObject.EvaluateJS(@"
                  window.Unity = {
                    call: function(msg) {
                      var iframe = document.createElement('IFRAME');
                      iframe.setAttribute('src', 'unity:' + msg);
                      document.documentElement.appendChild(iframe);
                      iframe.parentNode.removeChild(iframe);
                      iframe = null;
                    }
                  }
                ");

If you only need to support WKWebView and not UIWebView, you can also utilize the WKWebView's scriptMessageHandler, which is more reliable. Instead of Unity.call() you can call window.webkit.messageHandlers.unityControl.postMessage().

Thanks the iframe method seems to work fine. I only need to support WKWebView. I would be interested in the MessageHandlers to see if there is any speed difference. Is it currently implemented? I tried window.webkit.messageHandlers.unityControl.postMessage()
but window.webkit is undefined.

[KojiNakamaru]

Yes, it is implemented. Please note that even if you specify enableWKWebView: true it might become undefined because the plugin falls back to UIWebView if the target iOS doesn't support WKWebView.

I'm trying it in the unity editor on a mac osx sierra. Is that why it would be undefined?

If I call
window.webkit.messageHandlers.unityControl.postMessage('someMessage');
do I have to create a function in the sampleWebView named unityControl to receive the string?

[KojiNakamaru]

Ah, sorry, it is only implemented for the iOS version. It should work on iOS devices.

The webkit method is much faster in my tests. Thanks.
