Driver SDK를 초기화하고 GMTDDeliveryDriverAPI 인스턴스를 만든 후 이벤트 리스너를 설정하여 Fleet Engine과 백엔드로 전송된 차량 업데이트의 성공 또는 실패를 모니터링할 수 있습니다. 이러한 리스너는 백엔드와의 통신이 실패하는 경우 운전자에게 알리는 등 운전자 앱 내에서 작업을 트리거할 수 있습니다.
차량 업데이트 이벤트 수신 대기
운전자가 운전자 앱에서 위치 업데이트를 사용 설정하면 Driver SDK가 GMTDDeliveryVehicleReporter 클래스를 통해 Fleet Engine과 고객 백엔드에 정기적인 차량 업데이트를 전송합니다. GMTDVehicleReporterListener 프로토콜을 설정하여 업데이트 이벤트에 앱이 응답하도록 할 수 있습니다.
GMTDVehicleReporterListener를 사용하면 다음 이벤트를 처리할 수 있습니다.
vehicleReporter:didSucceedVehicleUpdate
백엔드 서비스가 차량 위치 및 상태 업데이트를 수신했음을 드라이버 앱에 알립니다.
vehicleReporter:didFailVehicleUpdate:withError
차량 업데이트가 실패했음을 리스너에게 알립니다. 드라이버가 위치 업데이트를 사용 설정한 경우 GMTDDeliveryVehicleReporter 클래스는 계속해서 최신 데이터를 Fleet Engine에 전송합니다.
다음 예에서는 이러한 이벤트를 처리하도록 GMTDVehicleReporterListener를 설정하는 방법을 보여줍니다.

위치 업데이트 사용 설정
위치 업데이트를 사용 설정하려면 GMTDDeliveryVehicleReporter의 드라이버 앱에서 locationTrackingEnabled을 YES로 설정합니다. 그러면 GMTDDeliveryVehicleReporter 클래스가 위치 업데이트를 Fleet Engine에 자동으로 전송합니다. 또한 GMSNavigator가 탐색 모드에 있는 경우(setDestinations를 통해 목적지가 설정된 경우) GMTDDeliveryVehicleReporter 클래스는 경로 및 도착 예정 시간 업데이트를 자동으로 전송합니다.
Driver SDK는 운전자의 현재 탐색 경로와 일치하도록 경로를 설정합니다. 정확한 위치 업데이트를 보장하려면 -setDestinations:callback:의 경유지를 Fleet Engine의 목적지와 일치하도록 설정하세요.
다음 예는 위치 업데이트를 사용 설정하는 방법을 보여줍니다.
Swift
importGoogleRidesharingDriverprivateletproviderID="INSERT_YOUR_PROVIDER_ID"classSampleViewController:UIViewController,GMTDVehicleReporterListener{privateletmapView:GMSMapViewoverridefuncviewDidLoad(){// Assumes you have implemented the sample code up to this step.deliveryDriverAPI.vehicleReporter.locationTrackingEnabled=true}}

(선택사항) 업데이트 간격 설정
기본적으로 locationTrackingEnabled을 YES로 설정하면 Driver SDK가 10초 간격으로 위치 업데이트를 Fleet Engine에 전송합니다. locationUpdateInterval를 사용하여 업데이트 간격을 최소 5초 또는 최대 60초로 변경할 수 있습니다. 업데이트를 더 자주 실행하면 요청이 느려지고 오류가 발생할 수 있습니다.

These listeners can\ntrigger actions within your driver app, such as notifying the driver if\ncommunication with your backend fails.\n\n### Listen for vehicle update events\n\nWhen the driver enables location updates in the driver app, the Driver SDK sends\nregular vehicle updates to Fleet Engine and the customer backend through the\n`GMTDDeliveryVehicleReporter` class. You can have the app respond to update\nevents by setting up the `GMTDVehicleReporterListener` protocol.\n\nWith `GMTDVehicleReporterListener`, you can handle the following events:\n\n- `vehicleReporter:didSucceedVehicleUpdate`\n\n Informs the Driver app that the backend services successfully received the\n vehicle location and state update.\n- `vehicleReporter:didFailVehicleUpdate:withError`\n\n Informs the listener that a vehicle update failed. As long as the driver has\n location updates enabled, the `GMTDDeliveryVehicleReporter` class continues\n to send the latest data to Fleet Engine.\n\nThe following example shows how to set up `GMTDVehicleReporterListener` to\nhandle these events: \n\n### Swift\n\n import GoogleRidesharingDriver\n\n private let providerID = \"INSERT_YOUR_PROVIDER_ID\"\n\n class SampleViewController: UIViewController, GMTDVehicleReporterListener {\n private let mapView: GMSMapView\n\n override func viewDidLoad() {\n // Assumes you have implemented the sample code up to this step.\n deliveryDriverAPI.vehicleReporter.add(self)\n }\n\n func vehicleReporter(_ vehicleReporter: GMTDDeliveryVehicleReporter, didSucceed vehicleUpdate: GMTDVehicleUpdate) {\n // Handle update succeeded.\n }\n\n func vehicleReporter(_ vehicleReporter: GMTDDeliveryVehicleReporter, didFail vehicleUpdate: GMTDVehicleUpdate, withError error: Error) {\n // Handle update failed.\n }\n }\n\n### Objective-C\n\n SampleViewController.h\n @interface SampleViewController : UIViewController\u003cGMTDVehicleReporterListener\u003e\n @end\n\n SampleViewController.m\n #import \"SampleViewController.h\"\n #import \"SampleAccessTokenProvider.h\"\n #import \u003cGoogleRidesharingDriver/GoogleRidesharingDriver.h\u003e\n\n static NSString *const PROVIDER_ID = @\"INSERT_YOUR_PROVIDER_ID\";\n\n @implementation SampleViewController {\n GMSMapView *_mapView;\n }\n\n - (void)viewDidLoad {\n // ASSUMES YOU IMPLEMENTED HAVE THE SAMPLE CODE UP TO THIS STEP.\n [delivervehicleReporter addListener:self];\n }\n\n - (void)vehicleReporter:(GMTDDeliveryVehicleReporter *)vehicleReporter didSucceedVehicleUpdate:(GMTDVehicleUpdate *)vehicleUpdate {\n // Handle update succeeded.\n }\n\n - (void)vehicleReporter:(GMTDDeliveryVehicleReporter *)vehicleReporter didFailVehicleUpdate:(GMTDVehicleUpdate *)vehicleUpdate withError:(NSError *)error {\n // Handle update failed.\n }\n\n @end\n\nEnable location updates\n-----------------------\n\nTo enable location updates, in the driver app on\n`GMTDDeliveryVehicleReporter`, set `locationTrackingEnabled` to\n`YES`. Then the\n`GMTDDeliveryVehicleReporter` class automatically sends location updates to\nFleet Engine. Additionally, when the `GMSNavigator` is in navigation mode, which\nis when a destination is set through `setDestinations`, the\n`GMTDDeliveryVehicleReporter` class automatically sends route and ETA updates.\n\nThe Driver SDK sets the route to match the driver's current navigation path. To\nensure accurate location updates, set the waypoint in\n`-setDestinations:callback:` to match the destination in Fleet Engine.\n\nThe following example shows how to enable location updates: \n\n### Swift\n\n import GoogleRidesharingDriver\n\n private let providerID = \"INSERT_YOUR_PROVIDER_ID\"\n\n class SampleViewController: UIViewController, GMTDVehicleReporterListener {\n private let mapView: GMSMapView\n\n override func viewDidLoad() {\n // Assumes you have implemented the sample code up to this step.\n deliveryDriverAPI.vehicleReporter.locationTrackingEnabled = true\n }\n }\n\n### Objective-C\n\n SampleViewController.m\n #import \"SampleViewController.h\"\n #import \"SampleAccessTokenProvider.h\"\n #import \u003cGoogleRidesharingDriver/GoogleRidesharingDriver.h\u003e\n\n static NSString *const PROVIDER_ID = @\"INSERT_YOUR_PROVIDER_ID\";\n\n @implementation SampleViewController {\n GMSMapView *_mapView;\n }\n\n - (void)viewDidLoad {\n // ASSUMES YOU HAVE IMPLEMENTED THE SAMPLE CODE UP TO THIS STEP.\n deliveryDriverAPI.vehicleReporter.locationTrackingEnabled = YES;\n }\n\n @end\n\n| **Note:** If the device has not moved since the last location update, the `GMSRoadSnappedLocationProvider` class does not send location updates continuously. For example, if a driver is waiting idle in the car. If you want to send a new location update, and have set `GMTDDeliveryVehicleReporter` as a listener after calling `startUpdatingLocation` on `GMSRoadSnappedLocationProvider`, you need to stop and start `GMSRoadSnappedLocationProvider`.\n\n### (Optional) Set the update interval\n\nBy default, when you set `locationTrackingEnabled` to `YES`, the Driver SDK\nsends location updates to Fleet Engine at a 10-second interval. You can change\nthe update interval with `locationUpdateInterval` to a minimum update interval\nof 5 seconds or a maximum of 60 seconds. More frequent updates may result in\nslower requests and errors."]]
