自訂標記

選取平台： Android iOS JavaScript

自訂標記 (或折線) 之前，您必須先將 使用者介面自訂選項。

初始化 UI 自訂選項

建議的回呼，用來初步設定 UI 自訂選項 是在 GMTCMapViewDelegate 中宣告。mapViewDidInitialize GMTCMapView 物件準備好算繪地圖時，就會觸發回呼。 樣式協調器已初始化，但未顯示 UI 元素。

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.
}

自訂標記

下例使用 GMTCMapView 自訂標記樣式。 如要設定標記類型及其屬性，請使用 setMarkerStyleOptions(_:markerType:)。您的自訂標記選項會覆寫 Consumer SDK 提供的預設值。

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];
}

標記類型

你可以自訂下列標記：

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

使用GMTCCustomizableMarkerType.tripPickupPoint， GMTCCustomizableMarkerType.intermediateDestination和 GMTCCustomizableMarkerType.tripDropoffPoint即可自訂路線控點 分享旅程

使用 GMTCCustomizableMarkerType.tripVehicle 自訂車輛圖示 分享歷程標記圖示不會改變 根據行程的實際交通工具類型而定。

標記選項

每個標記都可以自訂的屬性，都是 「Google 地圖」提供的房源 MarkerOptions。 消費者 SDK GMTCMarkerStyleOptions 具有以下特徵：

  • 使用初始化器建構
  • 建構後即無法變更。
  • 有預設值，因此您只需要指定任何自訂值。

您可以自訂下列屬性：

  • groundAnchor
  • isVisible：如要關閉標記，請將 isVisible 設為 false。資料足夠 能讓您使用自己的 UI 元素。
  • iconView
  • icon
  • zIndex
  • isFlat

範例

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];
}

取貨標記動態預計到達時間更新

如要建立能定期動態顯示更新後的預計到達時間的取貨標記， 更新應用程式的標記樣式選項 GMTCCustomizableMarkerType.tripPickupPoint。

範例

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];
