在自定义标记(或多段线)之前,您首先需要将 界面自定义选项。
初始化界面自定义选项
用于初始设置界面自定义选项的建议回调在 GMTCMapViewDelegate
中声明。mapViewDidInitialize
回调将在 GMTCMapView
对象准备好渲染地图时触发。
样式协调器已初始化,但不存在任何界面元素。
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.
}
自定义标记
以下示例使用 GMTCMapView
来自定义标记样式。
要设置标记的类型及其属性,请使用
setMarkerStyleOptions(_:markerType:)
。您的自定义标记选项会替换 Consumer SDK 提供的默认值。
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];
}
标记类型
您可以自定义以下标记:
GMTCCustomizableMarkerType.unknown
GMTCCustomizableMarkerType.tripPickupPoint
GMTCCustomizableMarkerType.tripDropoffPoint
GMTCCustomizableMarkerType.tripVehicle
GMTCCustomizableMarkerType.intermediateDestination
使用 GMTCCustomizableMarkerType.tripPickupPoint
、GMTCCustomizableMarkerType.intermediateDestination
和 GMTCCustomizableMarkerType.tripDropoffPoint
在分享行程期间自定义航点。
使用 GMTCCustomizableMarkerType.tripVehicle
可在分享行程期间自定义车辆图标。标记图标没有变化
。
标记选项
可用于每个标记的自定义属性是 Google 地图 MarkerOptions
提供的属性的一部分。消费者 SDK
GMTCMarkerStyleOptions
具有以下特征:
- 使用初始化程序构建
- 构建后不可更改。
- 具有默认值,因此您只需指定任何自定义值。
您可以自定义以下属性:
groundAnchor
isVisible
:如需关闭标记,请将isVisible
设置为 false。数据充足 可让您使用自己的界面元素来代替。iconView
icon
zIndex
isFlat
示例
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];
}
更新了自提标记的动态预计到达时间
如需创建一个会定期动态显示更新后的预计到达时间的接人点标记,请更新 GMTCCustomizableMarkerType.tripPickupPoint
的标记样式选项。
示例
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];
}
