Получение времени до следующего пункта назначения
Чтобы узнать время до следующего пункта назначения, вызовите timeToNextDestination() . Это возвращает значение NSTimeInterval . В следующем примере показана регистрация времени до следующего пункта назначения:
Быстрый
ifletnavigator=mapView.navigator{lettime=navigator.timeToNextDestinationletminutes=floor(time/60)letseconds=round(time-minutes*60)NSLog("Time to next destination: %.0f:%.0f",minutes,seconds)}
Цель-C
NSTimeIntervaltime=_mapView.navigator.timeToNextDestination;intminutes=floor(time/60);intseconds=round(time-minutes*60);NSLog(@"%@",[NSStringstringWithFormat:@"Time to next destination: %i:%i.",minutes,seconds]);
Получение расстояния до следующего пункта назначения
Чтобы получить расстояние до следующего пункта назначения, вызовите distanceToNextDestination() . Это возвращает значение CLLocationDistance . Единицы измерения указаны в метрах.
Быстрый
ifletnavigator=mapView.navigator{letdistance=navigator.distanceToNextDestinationletmiles=distance*0.00062137NSLog("Distance to next destination: %.2f miles.",miles)}
Цель-C
CLLocationDistancedistance=_mapView.navigator.distanceToNextDestination;doublemiles=distance*0.00062137;NSLog(@"%@",[NSStringstringWithFormat:@"Distance to next destination: %.2f.",miles]);
Получение условий движения до следующего пункта назначения
Чтобы получить значение, указывающее поток трафика к следующему пункту назначения, вызовите delayCategoryToNextDestination . Этот параметр возвращает GMSNavigationDelayCategory . В следующем примере показана оценка результата и регистрация сообщения о дорожном движении:
Быстрый
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).")}
Цель-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]);
Получение информации о текущем этапе
Чтобы получить информацию о текущем участке маршрута, вызовите currentRouteLeg . Это возвращает экземпляр GMSRouteLeg , из которого вы можете получить:
Место назначения ноги.
Конечная координата в ноге.
Путь, содержащий координаты, составляющие участок маршрута.
В следующем примере показана регистрация названия и координат широты и долготы для следующего участка маршрута:
Чтобы получить последний пройденный путь, вызовите traveledPath . Это возвращает экземпляр GMSPath , который был упрощен для удаления избыточных точек (например, превращение последовательных коллинеарных точек в один сегмент линии). Этот путь пуст, пока не начнется наведение. В следующем примере показано получение последнего пройденного пути:
Быстрый
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))")}}
Цель-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);}
