Is there a documented API for launching Nokia's HERE Maps iOS app for turn-by-turn navigation ?
here-place://lat,lon e.g. here-place://48.866833,2.355411
to open Here on a given place.
here-route://lat1,lon1,name1/lat2,lon2,name2
to start turn by turn navigation from lat1,lon1 to lat2,lon2.
here-route:///lat2,lon2,name2
to start a turn by turn navigation from the user location to lat2,lon2.
EDIT: It seems that name fields now support URL percent escaping to encode space and other characters (Tested in Here WeGo v2.0.11. Thank you marcel for the head up).
