In der Google Maps Platform stehen bald neue Kartenstile zur Verfügung. Dieses Update für die Kartenstile umfasst eine neue Standardfarbvorlage und Verbesserungen bei der Nutzerfreundlichkeit und Nutzerfreundlichkeit von Karten. Alle Kartenstile werden im März 2025 automatisch aktualisiert. Weitere Informationen zur Verfügbarkeit und zur früheren Aktivierung finden Sie unter Neuer Kartenstil für die Google Maps Platform.

Zeit bis zum nächsten Ziel abrufen
Wenn Sie die Zeit bis zum nächsten Ziel erfahren möchten, sagen Sie timeToNextDestination().
Dies gibt einen NSTimeInterval-Wert zurück. Im folgenden Beispiel wird die Zeit bis zum nächsten Ziel aufgezeichnet:
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
Wenn Sie die Entfernung zum nächsten Ziel ermitteln möchten, geben Sie distanceToNextDestination() ein.
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 zum nächsten Ziel abrufen
Wenn Sie einen Wert für den Trafficfluss zum nächsten Ziel abrufen möchten, rufen Sie delayCategoryToNextDestination auf.
Dieser Parameter gibt GMSNavigationDelayCategory zurück. Im folgenden Beispiel wird das Ergebnis ausgewertet und eine Verkehrsnachricht 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 Streckenabschnitt zu erhalten.
Dies gibt eine GMSRouteLeg-Instanz zurück, aus der Sie Folgendes abrufen können:
Das Ziel für den Abschnitt.
Die letzte Koordinate des Abschnitts.
Der Pfad mit den Koordinaten, aus denen sich der Streckenabschnitt zusammensetzt.
Im folgenden Beispiel wird veranschaulicht, wie der Titel und die Koordinaten für den nächsten Streckenabschnitt protokolliert werden:
Rufen Sie traveledPath auf, um den zuletzt zurückgelegten Weg abzurufen.
Dies gibt eine GMSPath-Instanz zurück, die vereinfacht wurde, um redundante Punkte zu entfernen (z. B. werden aufeinanderfolgende, auf einer Linie liegende Punkte in ein einzelnes Liniensegment umgewandelt). Dieser Pfad ist leer, bis die Navigation gestartet wird. Im folgenden Beispiel wird der zuletzt zurückgelegte Weg abgerufen:
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);}
