Untuk menggunakan gaya visual berbasis data untuk batas, Anda harus membuat ID peta. Selanjutnya, Anda harus membuat gaya peta baru, memilih lapisan fitur batas yang diperlukan, dan mengaitkan gaya dengan ID peta Anda.
Membuat ID peta
mapID adalah ID unik yang mewakili
satu instance Google Maps. Anda dapat membuat ID peta dan memperbarui gaya yang dikaitkan dengan ID peta kapan saja di Konsol Google Cloud.
Membuat gaya peta baru
Untuk membuat gaya peta baru, ikuti petunjuk di bagian Mengelola gaya peta untuk membuat gaya. Setelah selesai, kaitkan gaya dengan ID peta yang baru dibuat.
Memilih lapisan fitur
Di Konsol Google Cloud, Anda dapat memilih lapisan fitur mana yang akan ditampilkan. Lapisan ini menentukan jenis batas yang muncul di peta (misalnya lokalitas, negara bagian, dan sebagainya).
Klik drop-down Feature layers untuk menambahkan atau menghapus lapisan.
Klik Save untuk menyimpan perubahan dan menyediakannya untuk peta Anda.
Memperbarui kode inisialisasi peta
Langkah ini mengharuskan ID peta dikaitkan dengan gaya yang memiliki satu atau beberapa lapisan fitur yang diaktifkan. Untuk memverifikasi bahwa ID peta Anda disiapkan dengan benar di
Konsol Cloud, tinjau cara konfigurasinya di bagian Pengelolaan
Peta.

Objective-C
// A map ID using a style with one or more feature layers enabledGMSMapID*mapID=[GMSMapIDmapIDWithIdentifier:@"MAP_ID"];GMSMapView*mapView=[GMSMapViewmapWithFrame:CGRectZeromapID:mapIDcamera:[GMSCameraPositioncameraWithLatitude:40longitude:-80zoom:7]];
Menambahkan lapisan fitur ke peta
Untuk mendapatkan referensi ke lapisan fitur pada peta Anda, panggil
mapView.featureLayer(of:)
saat peta melakukan inisialisasi:
Gaya visual berbasis data untuk batas memerlukan kemampuan yang diaktifkan di konsol Google Cloud, dan dikaitkan dengan ID peta. Karena ID peta dapat berubah, Anda dapat memanggil
mapView.mapCapabilities
di GMSMapView untuk memverifikasi apakah kemampuan tertentu (misalnya, gaya visual berbasis data) tersedia sebelum memanggilnya.
Anda juga dapat mendeteksi perubahan pada kemampuan peta dengan berlangganan
GMSViewDelegate. Contoh ini menunjukkan cara menggunakan
protokol untuk memeriksa persyaratan penataan gaya berbasis data.

Next, you\nmust create a new map style, select the needed boundary feature layers, and\nassociate the style with your map ID.\n\nCreate a map ID\n\nA [mapID](/maps/documentation/get-map-id) is a unique identifier that represents\na single instance of a Google Map. You can create map IDs and update a style\nassociated with a map ID at any time in the Google Cloud console.\n\nCreate a new map style\n\nTo create a new map style, follow the instructions in [Manage map\nstyles](/maps/documentation/ios-sdk/cloud-customization/map-styles) to create\nthe style. Once complete associate the style with the newly created map ID.\n| **Experimental:** This feature can only be set for light map styles. When you link a light map style that has this feature enabled to a [map\n| ID](../map-ids/mapid-over), the enabled layers are also available for the dark map style.\n\nSelect feature layers\n\nIn the Google Cloud console you can select which feature layers to display. This\ndetermines which kinds of boundaries appear on the map (for example localities,\nstates, and so on).\n| **Important:** For optimal performance, only select the layers you need.\n\nManage feature layers\n\n1. In the Google Cloud console, [go to the Map Styles\n page](https://console.cloud.google.com/project/_/google/maps-apis/studio/styles)\n\n2. Select a project if prompted.\n\n3. Select a map style.\n\n4. Click the **Feature layers** drop-down to add or remove layers.\n\n5. Click **Save** to save your changes and make them available to your maps.\n\nUpdate your map initialization code\n\nThis step requires a map ID be associated with a style with one or more feature\nlayers enabled. To verify your map ID is set up correctly in\nCloud console, review how it is configured under [Maps\nManagement](https://console.cloud.google.com/google/maps-apis/studio/maps). \n\nSwift \n\n```swift\n// A map ID using a style with one or more feature layers enabled\n\nlet mapID = GMSMapID(identifier: \"YOUR_MAP_ID\")\nlet mapView = GMSMapView(frame: .zero, mapID: mapID, camera: GMSCameraPosition(latitude: 40, longitude: -80, zoom: 7))\n```\n\nObjective-C \n\n```objective-c\n// A map ID using a style with one or more feature layers enabled\n\nGMSMapID *mapID = [GMSMapID mapIDWithIdentifier:@\"MAP_ID\"];\nGMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero mapID:mapID camera:[GMSCameraPosition cameraWithLatitude:40 longitude:-80 zoom:7]];\n```\n| **Important:** For testing, you can skip the step of creating and configuring a [map\n| ID](/maps/documentation/get-map-id), by using mapId: [`DEMO_MAP_ID`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapID) in your app code. `DEMO_MAP_ID` is intended for testing purposes only. Don't use `DEMO_MAP_ID` in a production environment.\n\nAdd feature layers to a map\n\nTo get a reference to a feature layer on your map, call\n[`mapView.featureLayer(of:)`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapView#-featurelayeroffeaturetype:)\nwhen the map initializes: \n\nSwift \n\n```swift\nlet layer = mapView.featureLayer(of: .locality)\n```\n\nObjective-C \n\n```objective-c\nGMSFeatureLayer *layer = [mapView featureLayerOfFeatureType:GMSFeatureTypeLocality];\n```\n\nCheck map capabilities\n\nData-driven styling for boundaries requires capabilities which are enabled in the\nGoogle Cloud console, and associated with a map ID. Because map IDs are subject to\nchange, you can call\n[`mapView.mapCapabilities`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapView#mapcapabilities)\non a [`GMSMapView`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapView) to verify whether a certain capability (for\nexample data-driven styling) is available prior to calling it.\n\nYou can also detect changes in map capabilities by subscribing to\n[`GMSViewDelegate`](/maps/documentation/ios-sdk/reference/objc/Protocols/GMSMapViewDelegate). This example shows how to use the\nprotocol to check for data-driven styling requirements. \n\nSwift \n\n```swift\nclass SampleViewController: UIViewController {\n\n private lazy var mapView: GMSMapView = GMSMapView(frame: .zero, mapID: GMSMapID(identifier: \"YOUR_MAP_ID\"), camera: GMSCameraPosition(latitude: 40, longitude: -80, zoom: 7))\n\n override func loadView() {\n self.view = mapView\n mapView.delegate = self\n }\n}\n\nextension SampleViewController: GMSMapViewDelegate {\n func mapView(_ mapView: GMSMapView, didChange mapCapabilities: GMSMapCapabilityFlags) {\n if (!mapCapabilities.contains(.dataDrivenStyling)) {\n // Data-driven styling is *not* available, add a fallback.\n // Existing feature layers are also unavailable.\n }\n }\n}\n```\n\nObjective-C \n\n```objective-c\n@interface SampleViewController: UIViewController \u003cGMSMapViewDelegate\u003e\n@end\n\n@implementation SampleViewController\n- (void)loadView {\n GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero mapID:[GMSMapID mapIDWithIdentifier:@\"MAP_ID\"] camera:[GMSCameraPosition cameraWithLatitude:40 longitude:-80 zoom:7]];\n mapView.delegete = self;\n self.view = mapView;\n}\n\n- (void)mapView:(GMSMapView *)mapView didChangeMapCapabilities:(GMSMapCapabilityFlags)mapCapabilities {\n if (!(mapCapabilities & GMSMapCapabilityFlagsDataDrivenStyling)) {\n // Data-driven styling is *not* available, add a fallback.\n // Existing feature layers are also unavailable.\n }\n}\n@end\n```"]]
