Para usar el diseño basado en datos para los límites, debes crear un ID de mapa. A continuación, debes crear un nuevo diseño de mapa, seleccionar las capas de elementos de límite necesarias y asociar el diseño con tu ID de mapa.
Crea un ID de mapa
Un mapID es un identificador único que representa una sola instancia de un mapa de Google. Puedes crear IDs de mapa y actualizar los estilos asociados con estos en cualquier momento en Google Cloud Console.
Crea un nuevo diseño de mapa
Para crear un nuevo diseño de mapa, sigue las instrucciones que se indican en Cómo administrar diseños de mapa. Una vez que se complete, asocia el diseño con el ID de mapa recién creado.
Selecciona capas de elementos
En la consola de Google Cloud, puedes seleccionar las capas de componentes que deseas mostrar. Esto determina qué tipos de límites aparecerán en el mapa (por ejemplo, localidades, estados, etcétera).
Haz clic en el menú desplegable Capas de componentes para agregar o quitar capas.
Haz clic en Guardar para guardar los cambios y que estén disponibles en tus mapas.
Actualiza el código de inicialización del mapa
Este paso requiere que un ID de mapa esté asociado a un diseño con una o más capas de componentes habilitadas. Para verificar que tu ID de mapa esté configurado correctamente en la consola de Cloud, revisa cómo está configurado en Administración de mapas.

Agrega capas de elementos a un mapa
Para obtener una referencia a una capa de componentes del mapa, llama a mapView.featureLayer(of:) cuando se inicialice el mapa:
El diseño basado en datos aplicable a límites requiere capabilities que están habilitadas en la Consola de Google Cloud y asociadas a un ID de mapa. Dado que los IDs de mapa están sujetos a cambios, puedes llamar a mapView.mapCapabilities en un GMSMapView para verificar si una función determinada (por ejemplo, el diseño basado en datos) está disponible antes de llamarla.
También puedes detectar cambios en las capacidades del mapa si te suscribes a GMSViewDelegate. En este ejemplo, se muestra cómo usar el protocolo para verificar los requisitos de diseño basado en datos.

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```"]]
