Navigation SDK는 현재 일부 고객만 사용할 수 있습니다. 자세한 내용은 영업팀에 문의하세요.
새로운 지도 스타일 지정 기능이 곧 Google Maps Platform에 도입될 예정입니다. 이번 지도 스타일 지정 업데이트에는 새로운 기본 색상 팔레트가 추가되었으며 지도 환경 및 사용성이 개선되었습니다. 모든 지도 스타일은 2025년 3월에 자동으로 업데이트됩니다. 사용 가능 여부 및 이전에 선택한 방법에 대한 자세한 내용은 Google Maps Platform의 새 지도 스타일을 참고하세요.

필수 프로토콜에 대한 적합성 선언
탐색 메서드를 구현하기 전에 뷰 컨트롤러는 다음과 같이 프로토콜을 채택해야 합니다.
Swift
class ViewController: UIViewController, GMSNavigatorListener,
GMSRoadSnappedLocationProviderListener {
계속해서 위치 업데이트를 수신하려면 mapView.roadSnappedLocationProvider.startUpdatingLocation를 호출하고 GMSRoadSnappedLocationProviderListener를 사용하여 didUpdateLocation 이벤트를 처리합니다.
앱은 didArriveAtWaypoint 이벤트를 사용하여 대상에 도달했는지 감지합니다. continueToNextDestination()를 호출한 후 안내를 다시 사용 설정하여 안내를 재개하고 다음 경유지로 진행할 수 있습니다. 앱은 continueToNextDestination()를 호출한 후에 안내를 다시 사용 설정해야 합니다.
앱이 continueToNextDestination를 호출하면 탐색기에는 더 이상 이전 대상에 관한 데이터가 없습니다. 경로 구간에 대한 정보를 분석하려면 continueToNextDestination()를 호출하기 전에 탐색기에서 이를 검색해야 합니다.
다음 코드 예에서는 didArriveAtWaypoint 이벤트를 처리하는 메서드를 보여줍니다.
다음 목적지까지의 예상 시간의 최소 변경을 설정하려면 GMSNavigator에서 timeUpdateThreshold 속성을 설정합니다. 값은 초 단위로 지정됩니다. 이 속성을 설정하지 않으면 서비스에서 기본값 1초를 사용합니다.
Swift
navgator?.timeUpdateThreshold = 10
Objective-C
navgator.timeUpdateThreshold = 10;
목적지까지의 거리 업데이트 수신
목적지까지의 연속 거리 업데이트를 수신하려면 didUpdateRemainingDistance 이벤트를 처리하는 메서드를 만듭니다. distance 매개변수는 다음 목적지까지의 예상 거리를 미터 단위로 제공합니다.
Swift
함수 navigator(_ navigator: GMSNavigator, doUpdateRemainingDistancedistance:
CLLocationDistance) { let miles = distance * 0.00062137 print("Distance to 다음 목적지: (miles)miles.") }
다음 목적지까지의 예상 거리의 최소 변경을 설정하려면 GMSNavigator에서 distanceUpdateThreshold 속성을 설정합니다 (값이 미터 단위로 지정됨). 이 속성을 설정하지 않으면 서비스는 기본값 1미터를 사용합니다.
Swift
navgator?.distanceUpdateThreshold = 100
Objective-C
navgator.distanceUpdateThreshold = 100;
교통정보 업데이트 받기
나머지 경로의 트래픽 흐름에 관한 지속적인 업데이트를 수신하려면 didUpdateDelayCategory 이벤트를 처리하는 메서드를 만듭니다. delayCategoryToNextDestination를 호출하면 0~3의 값을 제공하는 GMSNavigationDelayCategory가 반환됩니다. 카테고리 업데이트는 앱 사용자의 현재
위치를 기반으로 합니다. 트래픽 데이터를 사용할 수 없는 경우 GMSNavigationDelayCategory는 0을 반환합니다. 숫자 1~3은 흐름이 약함에서 심함으로 증가하는 것을 나타냅니다.
Swift
functionc navigator(_ navigator: GMSNavigator, doUpdate모든 지연 카테고리:
GMSNavigationDelayCategory) { print("Traffic flow to next destination:
(delayCategory)") }
