> WKUserContentController - add a script message handler with name "cordova":
> https://developer.apple.com/library/prerelease/ios/documentation/WebKit/Reference/WKUserContentController_Ref/index.html#//apple_ref/swift/cl/WKUserContentController
> The WKUserContentController is associated with a WKWebViewConfiguration which is initialized with a WKWebView.
> {code}
> WKUserContentController* userContentController = [[WKUserContentController alloc] init];
> // scriptMessageHandler is the object that conforms to the WKScriptMessageHandler protocol
> // see https://developer.apple.com/library/prerelease/ios/documentation/WebKit/Reference/WKScriptMessageHandler_Ref/index.html#//apple_ref/swift/intf/WKScriptMessageHandler
> [userContentController addScriptMessageHandler:scriptMessageHandler name:@"cordova"];
> {code}
> In JavaScript, you would call into Objective-C thus:
> {code}
> var command = { callbackId: "blabla23", service:"Camera", action: "takePicture", actionArgs: [ 1, 2, 3 ] };
> window.webkit.messageHandlers.cordova.postMessage(command);
> {code}
> In the object that conforms to the WKScriptMessageHandler protocol:
> {code}
> - (void)userContentController:(WKUserContentController *)userContentController   didReceiveScriptMessage:(WKScriptMessage *)message
> {
>     if (![message.name isEqualToString:@"cordova"]) {
>         return;
>     }
>     NSDictionary* command = message.body;
>     // TODO: get the callbackId, service, action, actionArgs keys and create a CDVInvokedUrlCommand, and dispatch it
> }
> {code}
