I'm asked to start navigation when a specific place is selected.

It is not supposed to use their search interface. I have to create my own UI, select a place there, and start navigation when the map is opened.

For the Blind mode, I already implemented it with some existing functions in Objc. https://github.com/hulop/NavCogIOSv3/blob/a25a85834ffb9644025692a69c91c26264a196ac/NavCog3/BlindViewController.m#L242

For the General and Wheelchair mode, however, it uses a HLPWebView library which is specifically designed for NavCog3. There is no way to start navigation programmatically with it.

The view: https://github.com/hulop/NavCogIOSv3/blob/master/NavCog3/ViewController.m HLPWebView: https://github.com/hulop/HLPWebView

I also asked the developer about it, but he did not designed that part. He gave me the JavaScript function. https://github.com/hulop/MapService/blob/30863ab7822326a433cef760fbe6b7a172f0068b/MapService/WebContent/js/mobile.js#L250

With this function, I still have no idea how to pass the data and start it from Objc code.
