Zeit bis zum nächsten Ziel abrufen
Rufen Sie timeToNextDestination() auf, um die Zeit bis zum nächsten Ziel zu erfahren.
Dadurch wird ein NSTimeInterval-Wert zurückgegeben. Im folgenden Beispiel wird die Zeit bis zum nächsten Ziel protokolliert:
Swift
ifletnavigator=mapView.navigator{lettime=navigator.timeToNextDestinationletminutes=floor(time/60)letseconds=round(time-minutes*60)NSLog("Time to next destination: %.0f:%.0f",minutes,seconds)}
Objective-C
NSTimeIntervaltime=_mapView.navigator.timeToNextDestination;intminutes=floor(time/60);intseconds=round(time-minutes*60);NSLog(@"%@",[NSStringstringWithFormat:@"Time to next destination: %i:%i.",minutes,seconds]);
Entfernung zum nächsten Ziel abrufen
Rufen Sie distanceToNextDestination() auf, um die Entfernung zum nächsten Ziel zu ermitteln.
Dadurch wird ein CLLocationDistance-Wert zurückgegeben. Die Einheiten werden in Metern angegeben.
Swift
ifletnavigator=mapView.navigator{letdistance=navigator.distanceToNextDestinationletmiles=distance*0.00062137NSLog("Distance to next destination: %.2f miles.",miles)}
Objective-C
CLLocationDistancedistance=_mapView.navigator.distanceToNextDestination;doublemiles=distance*0.00062137;NSLog(@"%@",[NSStringstringWithFormat:@"Distance to next destination: %.2f.",miles]);
Verkehrslage für das nächste Ziel abrufen
Rufen Sie delayCategoryToNextDestination auf, um einen Wert zu erhalten, der den Verkehrsfluss zum nächsten Ziel angibt.
Dieser Parameter gibt GMSNavigationDelayCategory zurück. Im folgenden Beispiel wird das Ergebnis ausgewertet und eine Verkehrsmeldung protokolliert:
Swift
ifletnavigator=mapView.navigator{// insert sample for evaluating traffic valueletdelay=navigator.delayCategoryToNextDestinationlettraffic="unavailable"switchdelay{case.noData:traffic="unavailable"case.heavy:traffic="heavy"case.medium:traffic="moderate"case.light:traffic="light"default:traffic="unavailable"}print("Traffic is \(traffic).")}
Objective-C
GMSNavigationDelayCategorydelay=mapView.navigator.delayCategoryToNextDestination;NSString*traffic=@"";switch(delayCategory){caseGMSNavigationDelayCategoryNoData:traffic=@"No Data";break;caseGMSNavigationDelayCategoryHeavy:traffic=@"Heavy";break;caseGMSNavigationDelayCategoryMedium:traffic=@"Medium";break;caseGMSNavigationDelayCategoryLight:traffic=@"Light";break;default:NSLog(@"Invalid delay category: %zd",delayCategory);}NSLog(@"%@",[NSStringstringWithFormat:@"Traffic is %@.",traffic]);
Informationen zum aktuellen Abschnitt abrufen
Rufen Sie currentRouteLeg auf, um Informationen zum aktuellen Routenabschnitt zu erhalten.
Dadurch wird eine GMSRouteLeg-Instanz zurückgegeben, aus der Sie Folgendes abrufen können:
Das Ziel des Legs.
Die letzte Koordinate im Abschnitt.
Der Pfad mit den Koordinaten, aus denen der Routenabschnitt besteht.
Im folgenden Beispiel werden der Titel und die Breiten-/Längengradkoordinaten für den nächsten Routenabschnitt protokolliert:
Rufen Sie traveledPath auf, um den zuletzt zurückgelegten Pfad abzurufen.
Dadurch wird eine GMSPath-Instanz zurückgegeben, die vereinfacht wurde, um redundante Punkte zu entfernen (z. B. werden aufeinanderfolgende kollineare Punkte in ein einzelnes Liniensegment umgewandelt). Dieser Pfad ist leer, bis die Anleitung gestartet wird. Das folgende Beispiel zeigt, wie der zuletzt zurückgelegte Pfad abgerufen wird:
Swift
ifletnavigator=mapView.navigator{letlatestPath=navigator.traveledPathiflatestPath.count() > 0{letbegin:CLLocationCoordinate2D=latestPath.coordinate(at:0)letcurrent:CLLocationCoordinate2D=latestPath.coordinate(at:latestPath.count()-1)print("Path from (\(begin.latitude),\(begin.longitude)) to (\(current.latitude),\(current.longitude))")}}
Objective-C
GMSPath*latestPath=mapView.navigator.traveledPath;if(latestPath.count > 0){CLLocationCoordinate2Dbegin=[latestPathcoordinateAtIndex:0];CLLocationCoordinate2Dcurrent=[latestPathcoordinateAtIndex:latestPath.count-1];NSLog(@"Path from %f/%f to %f/%f",begin.latitude,begin.longitude,current.latitude,current.longitude);}
