本節說明如何在伺服器比對行程與車輛後,設定車輛的目的地。
事前準備
您必須先完成下列項目,才能使用這個部分:
在駕駛應用程式中設定目的地
將乘客與駕駛員配對後,您必須在駕駛員應用程式中設定行程目的地,方法如下:
從車隊引擎中的路點集合中擷取車輛目的地,該集合是由
GetTrip()
、UpdateTrip()
和GetVehicle()
傳回。呼叫 Navigation SDK for iOS 方法來設定目的地
setDestinations()
。
以下範例說明如何在驅動程式中設定目的地 應用程式。
Swift
private func startNavigation() {
let destinations = [
GMSNavigationWaypoint(
placeID: "ChIJnUYTpNASkFQR_gSty5kyoUk", title: "PCC Natural Market"),
GMSNavigationWaypoint(
placeID: "ChIJJ326ROcSkFQRBfUzOL2DSbo", title: "Marina Park"),
]
mapView.navigator?.setDestinations(destinations, callback: { routeStatus in
guard routeStatus == .OK else {
// Error starting navigation.
return
}
mapView.locationSimulator?.simulateLocationsAlongExistingRoute()
mapView.navigator?.isGuidanceActive = true
mapView.navigator?.sendsBackgroundNotifications = true
mapView.cameraMode = .following
})
}
Objective-C
- (void)startNavigation {
NSArray<GMSNavigationWaypoint *> *destinations =
@[[[GMSNavigationWaypoint alloc] initWithPlaceID:@"ChIJnUYTpNASkFQR_gSty5kyoUk"
title:@"PCC Natural Market"],
[[GMSNavigationWaypoint alloc] initWithPlaceID:@"ChIJJ326ROcSkFQRBfUzOL2DSbo"
title:@"Marina Park"]];
[_mapView.navigator setDestinations:destinations
callback:^(GMSRouteStatus routeStatus) {
if (routeStatus != GMSRouteStatusOK) {
// Error starting navigation.
return;
}
[_mapView.locationSimulator simulateLocationsAlongExistingRoute];
_mapView.navigator.guidanceActive = YES;
_mapView.navigator.sendsBackgroundNotifications = YES;
_mapView.cameraMode = GMSNavigationCameraModeFollowing;
}];
}
