Wikitude

The targets and the AR content will added using Wikitude Studio.  I see from the Wikitude Studio Editor, we can download the JS experience. This pack can be plugged into the native iOS / Android app. I have downloaded the sample app. So far so good.

However we need to achieve 2 additional things for this app:

1. Some AR content items are buttons leading to a URL. Currently the app loads the URLs defined in the Wikitude Studio in a webview, but we would like to customize the way that webview looks. I do not see any code for the UIWebView in the xcode sample so I assume it is inside the SDK and not accessible to change?

2. We also need to trigger some native code when each target is detected.

For both the things above I was trying to implement architectView:invokedURL but I see it is deprecated and no longer works. Also if I change the URLs of the button to a custom scheme, the app crashed saying that "only http and https" is accepted. 

I found  

AR.platform.sendJSONObject() 

and

- (void)architectView:(WTArchitectView *)architectView receivedJSONObject:(NSDictionary *)jsonObject;

Can this be used to send a custom url scheme, so we can detect a load the url in our own custom web view? If so, is there a way we can attach this code to elements using the Wikitude Studio Editor?
