ios - SKMaps and ViaPoints/WayPoints -

i have questions regarding skmap sdk functionality.

after creating route , starting navigation process, there anyway of capturing waypoint/viapoint directed towards? after calculating route, seems routeinformation.viapointsonroute empty. calculateroute(route) automatically generate list of viapoints? in sknavigationdelegate protocol reference see following event functions :

– routingservice:didenterviapointarea: – routingservice:didreachviapointwithindex: – routingservice:didexitviapointarea: 

however, these methods never seem called. not sure if called if viapoints programmatically added.

also when routeservice fires currentadvice , nextadvice methods, skrouteavice location appear empty well.

is there anyway provide me simple example of how create , capture current waypoint position , next waypoint position while in navigation? essentially, trying calculate direction current location next waypoint.

below rough example of route , navigation initiation code:

//created route let route: skroutesettings = skroutesettings() route.routemode = skroutemode.pedestrian route.startcoordinate = coordinatecurrent! route.destinationcoordinate = coordinatedestination! route.shouldberendered = true  skroutingservice.sharedinstance().calculateroute(r oute)  //start navigation let navsettings: sknavigationsettings = sknavigationsettings() navsettings.navigationtype = sknavigationtype.simulation navsettings.distanceformat = skdistanceformat.milesfeet navsettings.viapointnotificationdistance=1 self.mapview!.settings.displaymode = skmapdisplaymode.mode3d navsettings.transportmode = sktransportmode.pedestrian skroutingservice.sharedinstance().startnavigationw ithsettings(navsettings)  //start postioner service skpositionerservice.sharedinstance().delegate = self skpositionerservice.sharedinstance().startlocation update() routeinfo.viapointsonroute  func routingservice(routingservice: skroutingservice!, didchangenextadvice nextadvice: skrouteadvice, islastadvice:bool) {     log(string(nextadvice.location)) }  func routingservice(routingservice: skroutingservice!, didchangecurrentadvice currentadvice: skrouteadvice, islastadvice:bool) {     log(string(currentadvice.location)) }  func routingservice(routingservice: skroutingservice!,                     didupdateviapointsinformation viapoints: [anyobject]!) {     log("via info: " + string(viapoints)) }  func routingservice(routingservice: skroutingservice!,                     didenterviapointarea index: int32) {     log("enter via: " + string(index)) }  func routingservice(routingservice: skroutingservice!,                     didexitviapointarea index: int32) {     log("exit via: " + string(index)) } 

thank time!

i think first have clarify terminology.

viapoint or waypoint (the skobbler/telenav sdk uses viapoint terminology) point on route explicitly declared "viapoint". these points added @ route calculation time (by passing array of viapoints in route settings) or during navigation addviapoint api.

these viapoints monitored sdk , you'll receive didenterviapointarea, didreachviapointwithindex , didexitviapointarea callbacks.

i believe you're using term waypoint describing "junction" or "point requiring advice" along route - these correspond "route coordinates" provided sdk (see routecoordinationsforroutewithid api). these route coordinates not explicitly surfaced sdk - don't explicit information these points indirect notifications in form of advices ("in 200 meters turn right onto main street").

what turn turn engine provides "direction" between 2 such coordinates (in form of advice: "carry straight on", "turn right", "turn left"). see documentation regarding how advices created more details (here , here)

maybe skobbler/telenav team can provide better advice if describe end goal (what use case trying achieve).
