請上車

本節說明如何準備車輛，以便接送乘客。您必須完成下列每個步驟，後端才能將車輛與行程配對。

設定事件監聽器

初始化驅動程式 SDK 並建立 GMTDRidesharingDriverAPI 後您可以設定事件監聽器，藉此監控車輛更新資料會傳送至 Fleet Engine 和您的後端這些事件監聽器可在駕駛應用程式中觸發動作，例如在與後端的通訊失敗時通知駕駛人。

監聽車輛更新事件

當駕駛者在駕駛者應用程式中啟用位置更新功能時，Driver SDK 會透過 GMTDVehicleReporter 類別，將定期的車輛更新資料傳送至車隊引擎和客戶後端。您可以讓應用程式做出回應即可設定 GMTDVehicleReporterListener 通訊協定來更新事件。

您可以使用 GMTDVehicleReporterListener 處理下列事件：

vehicleReporter:didSucceedVehicleUpdate

通知 Driver 應用程式，後端服務已成功收到車輛位置和狀態更新。
vehicleReporter:didFailVehicleUpdate:withError

通知事件監聽器無法更新車輛。只要駕駛人已啟用位置更新通知，GMTDVehicleReporter 類別會繼續傳送位置資訊最新資料傳送至 Fleet Engine

以下範例說明如何將 GMTDVehicleReporterListener 設定為處理這些事件：

Swift

import GoogleRidesharingDriver

private let providerID = "INSERT_YOUR_PROVIDER_ID"

class SampleViewController: UIViewController, GMTDVehicleReporterListener {
  private let mapView: GMSMapView

  override func viewDidLoad() {
    // Assumes you have implemented the sample code up to this step.
    ridesharingDriverAPI.vehicleReporter.add(self)
  }

  func vehicleReporter(_ vehicleReporter: GMTDVehicleReporter, didSucceed vehicleUpdate: GMTDVehicleUpdate) {
    // Handle update succeeded.
  }

  func vehicleReporter(_ vehicleReporter: GMTDVehicleReporter, didFail vehicleUpdate: GMTDVehicleUpdate, withError error: Error) {
    // Handle update failed.
  }
}

Objective-C

/**
 *   SampleViewController.h
 */
@interface SampleViewController : UIViewController<GMTDVehicleReporterListener>
@end

/**
 *   SampleViewController.m
 */
#import "SampleViewController.h"
#import "SampleAccessTokenProvider.h"
#import <GoogleRidesharingDriver/GoogleRidesharingDriver.h>

static NSString *const PROVIDER_ID = @"INSERT_YOUR_PROVIDER_ID";

@implementation SampleViewController {
  GMSMapView *_mapView;
}

- (void)viewDidLoad {
  // Assumes you have implemented the sample code up to this step.
  [ridesharingDriverAPI.vehicleReporter addListener:self];
}

- (void)vehicleReporter:(GMTDVehicleReporter *)vehicleReporter didSucceedVehicleUpdate:(GMTDVehicleUpdate *)vehicleUpdate {
  // Handle update succeeded.
}

- (void)vehicleReporter:(GMTDVehicleReporter *)vehicleReporter didFailVehicleUpdate:(GMTDVehicleUpdate *)vehicleUpdate withError:(NSError *)error {
  // Handle update failed.
}

@end

監聽車輛位置更新

Navigation SDK 透過 GMSRoadSnappedLocationProvider 類別。如要接收這類更新，您必須建立 GMTDVehicleReporter 做為事件監聽器。

Swift

import GoogleRidesharingDriver

private let providerID = "INSERT_YOUR_PROVIDER_ID"

class SampleViewController: UIViewController, GMTDVehicleReporterListener {
  private let mapView: GMSMapView

  override func viewDidLoad() {
    // Assumes you have implemented the sample code up to this step.
    if let roadSnappedLocationProvider = mapView.roadSnappedLocationProvider {
      roadSnappedLocationProvider.add(ridesharingDriverAPI.vehicleReporter)
      roadSnappedLocationProvider.startUpdatingLocation()
    }
  }
}

Objective-C

/**
 *   SampleViewController.h
 */
@interface SampleViewController : UIViewController<GMTDVehicleReporterListener>
@end

/**
 *   SampleViewController.m
 */
#import "SampleViewController.h"
#import "SampleAccessTokenProvider.h"
#import <GoogleRidesharingDriver/GoogleRidesharingDriver.h>

static NSString *const PROVIDER_ID = @"INSERT_YOUR_PROVIDER_ID";

@implementation SampleViewController {
  GMSMapView *_mapView;
}

- (void)viewDidLoad {
  // Assumes you have implemented the sample code up to this step.
  [_mapView.roadSnappedLocationProvider addListener:ridesharingDriverAPI.vehicleReporter];
  [_mapView.roadSnappedLocationProvider startUpdatingLocation];
}

@end

啟用位置更新通知

如要啟用位置更新功能，請在駕駛員應用程式中將 GMTDVehicleReporter 的 locationTrackingEnabled 設為 true。接著，GMTDVehicleReporter 類別會自動將位置更新資料傳送至 Fleet Engine。完成 Fleet Engine 後用於比對客戶後端服務，並將車輛指派給特定行程 GMTDVehicleReporter 類別會在 GMSNavigator 目前處於導覽模式，也就是透過以下方式設定目的地： setDestinations。

Driver SDK 會設定與驅動程式目前的導航路徑相符的路徑。為確保位置資訊更新準確無誤，請在 setDestinations 中設定路徑點，以便與 Fleet Engine 中的目的地相符。

以下範例說明如何啟用位置更新通知：

Swift

import GoogleRidesharingDriver

private let providerID = "INSERT_YOUR_PROVIDER_ID"

class SampleViewController: UIViewController, GMTDVehicleReporterListener {
  private let mapView: GMSMapView

  override func viewDidLoad() {
    // Assumes you have implemented the sample code up to this step.
    ridesharingDriverAPI.vehicleReporter.locationTrackingEnabled = true
  }
}

Objective-C

/**
 *   SampleViewController.m
 */
#import "SampleViewController.h"
#import "SampleAccessTokenProvider.h"
#import <GoogleRidesharingDriver/GoogleRidesharingDriver.h>

static NSString *const PROVIDER_ID = @"INSERT_YOUR_PROVIDER_ID";

@implementation SampleViewController {
  GMSMapView *_mapView;
}

- (void)viewDidLoad {
  // Assumes you have implemented the sample code up to this step.
  ridesharingDriverAPI.vehicleReporter.locationTrackingEnabled = YES;
}

@end

設定更新間隔

根據預設，將 locationTrackingEnabled 設為 true 時，驅動程式 SDK 會以 10 秒的間隔，將行程和車輛更新資料傳送至 Fleet Engine。您可以使用 locationUpdateInterval 將更新間隔變更為最小更新間隔 5 秒或最長更新間隔 60 秒。更新頻率越高，要求速度就會越慢，且可能發生錯誤。

將車輛狀態設為線上

啟用位置更新後，請將車輛狀態設為 ONLINE，以車輛可在 Fleet Engine 中搜尋。

以下範例說明如何將車輛狀態設為 ONLINE。適用對象詳情請參閱 updateVehicleState。

Swift

import GoogleRidesharingDriver

private let providerID = "INSERT_YOUR_PROVIDER_ID"

class SampleViewController: UIViewController, GMTDVehicleReporterListener {
  private let mapView: GMSMapView

  override func viewDidLoad() {
    // Assumes you have implemented the sample code up to this step.
    ridesharingDriverAPI.vehicleReporter.update(.online)
  }
}

Objective-C

#import "SampleViewController.h"
#import "SampleAccessTokenProvider.h"
#import <GoogleRidesharingDriver/GoogleRidesharingDriver.h>

static NSString *const PROVIDER_ID = @"INSERT_YOUR_PROVIDER_ID";

@implementation SampleViewController {
  GMSMapView *_mapView;
}

- (void)viewDidLoad {
  // Assumes you have implemented the sample code up to this step.
  [ridesharingDriverAPI.vehicleReporter
                                   updateVehicleState:GMTDVehicleStateOnline];
}

@end
