Sebelum menyesuaikan penanda (atau polyline), Anda harus melakukan inisialisasi opsi penyesuaian UI terlebih dahulu.
Melakukan inisialisasi opsi penyesuaian UI
Callback yang direkomendasikan yang digunakan untuk menetapkan opsi penyesuaian UI
pada awalnya dideklarasikan di GMTCMapViewDelegate
. mapViewDidInitialize
callback akan 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 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 perhentian selama
berbagi perjalanan.
Gunakan GMTCCustomizableMarkerType.tripVehicle
untuk menyesuaikan ikon kendaraan
selama 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 subset dari
properti yang disediakan oleh Google Maps
MarkerOptions
Consumer SDK
GMTCMarkerStyleOptions
memiliki karakteristik berikut:
- Dibangun menggunakan penginisialisasi
- Tidak dapat diubah setelah dibuat.
- Memiliki nilai default, jadi Anda hanya perlu menentukan nilai kustom.
Anda dapat menyesuaikan properti berikut:
groundAnchor
isVisible
: Untuk menonaktifkan penanda, tetapkanisVisible
ke salah. Cukup data harus disediakan agar Anda dapat menggunakan elemen UI sebagai penggantinya.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];
}
Pembaruan perkiraan waktu tiba dinamis untuk penanda pengambilan
Untuk membuat penanda pengambilan yang secara dinamis menampilkan perkiraan waktu tiba 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)
