Menyesuaikan penanda

Pilih platform: Android iOS JavaScript

Sebelum menyesuaikan penanda (atau polyline), Anda harus menginisialisasi opsi penyesuaian UI terlebih dahulu.

Menginisialisasi opsi penyesuaian UI

Callback yang direkomendasikan untuk menetapkan opsi penyesuaian UI pada awalnya dideklarasikan di GMTCMapViewDelegate. Callback mapViewDidInitialize dipicu saat objek GMTCMapView siap merender peta. Koordinator gaya diinisialisasi, tetapi tidak ada elemen UI.

Swift

/** ViewController.swift */

class ViewController: UIViewController, GMTCMapViewDelegate {

  // MARK: - GMTCMapViewDelegate

  func mapViewDidInitialize(_ mapview: GMTCMapView) {
    // Set the UI customization options here.
  }
}

Objective-C

/** ViewController.m */

@interface ViewController () <GMTCMapViewDelegate>

#pragma mark GMTCMapViewDelegate

- (void)mapViewDidInitialize:(GMTCMapView *)mapview {
  // Set the UI customization options here.
}

Menyesuaikan penanda

Contoh berikut menggunakan GMTCMapView untuk menyesuaikan gaya penanda. Untuk menetapkan jenis penanda dan propertinya, gunakan setMarkerStyleOptions(_:markerType:). Opsi penanda kustom Anda akan mengganti nilai default yang disediakan oleh Consumer SDK.

Swift

/** MapViewController.swift */

func updateMarkerUIOptions() {
  let customizableMarkerType = GMTCCustomizableMarkerType.tripVehicle
  let markerStyleOptions = GMTCMutableMarkerStyleOptions()
  markerStyleOptions.groundAnchor = groundAnchor
  markerStyleOptions.isVisible = true
  markerStyleOptions.icon = icon
  markerStyleOptions.zIndex = 100
  markerStyleOptions.isFlat = false
  let coordinator = self.mapView.consumerMapStyleCoordinator
  coordinator.setMarkerStyleOptions(markerStyleOptions, markerType: customizableMarkerType)
}

/** To restore the default values, call setMarkerStyleOptions(_:markerType:) using nil for the GMTCMarkerStyleOptions parameter.
Here is an example of retrieving the active GMTCMarkerStyleOptions. */

private func retrieveMarkerStyle(markerType: GMTCCustomizableMarkerType) {
  let styleCoordinator = mapView.consumerMapStyleCoordinator

  // The 'markerStyleOptions' contains the stored style options for this marker type.
  let markerStyleOptions = styleCoordinator.markerStyleOptions(for: markerType)
}

Objective-C

/** MapViewController.m */

- (void)updateMarkerUIOptions {
  // The marker type that you would like to set custom UI options for.
  GMTCCustomizableMarkerType customizableMarkerType = GMTCCustomizableMarkerTypeTripVehicle;

  GMTCMutableMarkerStyleOptions *markerStyleOptions =
      [[GMTCMutableMarkerStyleOptions alloc] init];
  markerStyleOptions.groundAnchor = groundAnchor;
  markerStyleOptions.isVisible = YES;
  markerStyleOptions.icon = icon;
  markerStyleOptions.zIndex = 100;
  markerStyleOptions.isFlat = NO;

  [[_mapView consumerMapStyleCoordinator] setMarkerStyleOptions:markerStyleOptions markerType:customizableMarkerType];
}

/** To restore the default values, call setMarkerStyleOptions:markerStyleOptions:markerType: using nil for the GMTCMarkerStyleOptions parameter.
Here is an example of retrieving the active GMTCMarkerStyleOptions. */

- (void)retrieveMarkerStyle:(GMTCCustomizableMarkerType)markerType {
  GMTCConsumerMapStyleCoordinator *styleCoordinator = _mapView.consumerMapStyleCoordinator;

  // The 'markerStyleOptions' contains the stored style options for this marker type.
  GMTCMarkerStyleOptions *markerStyleOptions = [styleCoordinator markerStyleOptionsForType:markerType];
}

Jenis penanda

Anda dapat menyesuaikan penanda berikut:

• GMTCCustomizableMarkerType.unknown
• GMTCCustomizableMarkerType.tripPickupPoint
• GMTCCustomizableMarkerType.tripDropoffPoint
• GMTCCustomizableMarkerType.tripVehicle
• GMTCCustomizableMarkerType.intermediateDestination

Gunakan GMTCCustomizableMarkerType.tripPickupPoint, GMTCCustomizableMarkerType.intermediateDestination, dan GMTCCustomizableMarkerType.tripDropoffPoint untuk menyesuaikan titik jalan saat berbagi perjalanan.

Gunakan GMTCCustomizableMarkerType.tripVehicle untuk menyesuaikan ikon kendaraan saat berbagi perjalanan. Ikon penanda tidak berubah sesuai dengan jenis kendaraan sebenarnya untuk perjalanan.

Opsi penanda

Properti yang dapat disesuaikan yang tersedia untuk setiap penanda adalah subkumpulan properti yang disediakan oleh Google Maps MarkerOptions. Consumer SDK GMTCMarkerStyleOptions memiliki karakteristik berikut:

• Dibuat menggunakan penginisialisasi
• Tidak dapat diubah setelah dibuat.
• Memiliki nilai default, sehingga Anda hanya perlu menentukan nilai kustom.

Anda dapat menyesuaikan properti berikut:

• groundAnchor
• isVisible: Untuk menonaktifkan penanda, tetapkan isVisible ke false. Data yang cukup harus disediakan agar Anda dapat menggunakan elemen UI Anda sendiri di tempatnya.
• iconView
• icon
• zIndex
• isFlat

Contoh

Swift

/** MapViewController.swift */

private func updateMarkerUIOptions() {
  // Get the GMTCConsumerMapStyleCoordinator
  let consumerMapStyleCoordinator = mapView.consumerMapStyleCoordinator

  // The marker type that you would like to set custom UI options for.
  let customizableMarkerType = GMTCCustomizableMarkerType.tripVehicle

  // Initializing marker options.
  let markerStyleOptions = GMTCMutableMarkerStyleOptions()
  markerStyleOptions.groundAnchor = kGMSMarkerDefaultGroundAnchor
  markerStyleOptions.icon = icon
  markerStyleOptions.zIndex = 100
  markerStyleOptions.isFlat = false
  markerStyleOptions.isVisible = true

  consumerMapStyleCoordinator.setMarkerStyleOptions(markerStyleOptions, markerType: customizableMarkerType)

  // Reset marker options to default values.
  consumerMapStyleCoordinator.setMarkerStyleOptions(nil, markerType: customizableMarkerType)
}

Objective-C

/** MapViewController.m */

- (void)updateMarkerUIOptions {
  // Get the GMTCConsumerMapStyleCoordinator
  GMTCConsumerMapStyleCoordinator *consumerMapStyleCoordinator = [_mapView consumerMapStyleCoordinator];

  // The marker type that you would like to set custom UI options for.
  GMTCCustomizableMarkerType customizableMarkerType = GMTCCustomizableMarkerTypeTripVehicle;

  // Initializing marker options.
  GMTCMutableMarkerStyleOptions *markerStyleOptions =
      [[GMTCMutableMarkerStyleOptions alloc] init];
  markerStyleOptions.groundAnchor = kGMSMarkerDefaultGroundAnchor;
  markerStyleOptions.icon = icon;
  markerStyleOptions.zIndex = 100;
  markerStyleOptions.isFlat = NO;
  markerStyleOptions.isVisible = YES;

  [consumerMapStyleCoordinator setMarkerStyleOptions:markerStyleOptions markerType:customizableMarkerType];

  // Reset marker options to default values.
  [consumerMapStyleCoordinator setMarkerStyleOptions:nil markerType:customizableMarkerType];
}

Update ETA dinamis untuk penanda penjemputan

Untuk membuat penanda penjemputan yang secara dinamis menampilkan ETA yang diperbarui secara berkala, perbarui opsi gaya penanda untuk GMTCCustomizableMarkerType.tripPickupPoint.

Contoh

Swift

/** MapViewController.swift */

/// Updates the ETA every minute by creating a Timer that repeats every minute.
private func schedulePickupMarkerStyleUpdates() {
  Timer.scheduledTimer(
    timeInterval: 60.0,  // Update marker ETA every minute.
    target: self,
    selector: #selector(updatePickupMarkerETA),
    userInfo: nil,
    repeats: true)
}

/// Updates the marker options for GMTCCustomizableMarkerType.tripPickupPoint for the current time.
@objc private func updatePickupMarkerETA() {
  let consumerMapStyleCoordinator = mapView.consumerMapStyleCoordinator
  let previousOptions = consumerMapStyleCoordinator.markerStyleOptions(for: .tripPickupPoint)

  // Get updated ETA icon.
  let updatedETAIcon = pickupIconForCurrentTime()

  let markerStyleOptions = GMTCMutableMarkerStyleOptions()
  markerStyleOptions.groundAnchor = kGMSMarkerDefaultGroundAnchor
  markerStyleOptions.icon = updatedETAIcon
  markerStyleOptions.zIndex = 100
  markerStyleOptions.isFlat = false
  markerStyleOptions.isVisible = true

  consumerMapStyleCoordinator.setMarkerStyleOptions(markerStyleOptions, markerType: .tripPickupPoint)
}

Objective-C

/** MapViewController.m */

/** Updates the ETA every minute by creating an NSTimer that repeats every minute. */
- (void)schedulePickupMarkerStyleUpdates {
  [NSTimer scheduledTimerWithTimeInterval:60.0 // Update marker ETA every minute.
                                   target:self
                                 selector:@selector(updatePickupMarkerETA)
                                 userInfo:nil
                                  repeats:YES];
}

/** Updates the marker options for GMTCCustomizableMarkerTypeTripPickupPoint for the current time. */
- (void)updatePickupMarkerETA {
  GMTCConsumerMapStyleCoordinator *consumerMapStyleCoordinator = [_mapView consumerMapStyleCoordinator];
  GMTCMarkerStyleOptions *previousOptions = [consumerMapStyleCoordinator markerStyleOptionsForType:GMTCCustomizableMarkerTypeTripPickupPoint];

  // Get updated ETA icon.
  UIImage *updatedETAIcon = [self pickupIconForCurrentTime];

  GMTCMutableMarkerStyleOptions *markerStyleOptions =
                               [[GMTCMutableMarkerStyleOptions alloc] init];
  markerStyleOptions.groundAnchor = kGMSMarkerDefaultGroundAnchor;
  markerStyleOptions.icon = updatedETAIcon;
  markerStyleOptions.zIndex = 100;
  markerStyleOptions.isFlat = NO;
  markerStyleOptions.isVisible = YES;

  [consumerMapStyleCoordinator setMarkerStyleOptions:markerStyleOptions markerType:GMTCCustomizableMarkerTypeTripPickupPoint];
}
