The following instructions show how to use the Google Cloud Console to create, customize, publish, and manage your maps at any time using Map IDs and Map Styles.
To create or manage any Map IDs or Map Styles in your Google Cloud project, you must have the Project Owner or Project Editor IAM role.
Before you begin
- Use Xcode Version 11 or later.
- Use the Maps Beta framework or Maps Beta CocoaPod.
- Have a working
UIViewControllerset to show a
Creating Map IDs
A Map ID is a unique identifier that represents a single instance of a Google Map. You can create Map IDs and update a style associated with a Map ID at any time in the Google Cloud Console without changing embedded JSON styling in your application code.
To create a Map ID:
In the Cloud Console, go to the Maps Management page.
Click Create New Map ID, to display the Create New Map ID form.
In the form, do the following:
- Specify a map name.
- Specify a map type or platform.
- Enter a description of the map.
- Click Next to display the new Map ID.
Using Map IDs in your application code
To instantiate a map using a Map ID, do the following:
- Create a
GMSMapIDwith the Map ID string from Google Cloud Console.
- Create a
GMSMapViewspecifying the Map ID you just created.
let camera = GMSCameraPosition(latitude: 47.0169, longitude: -122.336471, zoom: 12) let mapID = GMSMapID(identifier: "<YOUR MAP ID>") let mapView = GMSMapView(frame: .zero, mapID: mapID, camera: camera) self.view = mapView
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:47.0169 longitude:-122.336471 zoom:12]; GMSMapID *mapID = [GMSMapID mapIDWithIdentifier:@"<YOUR MAP ID>"]; GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero mapID:mapID camera:camera]; self.view = mapView;
If you are using your own Map ID, you can set your Map ID on Cloud Console to have a new style at any time, and that style will be reflected on your map view automatically for you and users within about six hours.
If you want to see the changes immediately, you can close out and restart your app by exiting the app, forcing a quit of the app from the recently used apps list, and then reopening it. The updated map will then be visible.
Creating map styles
A Map Style is a unique identifier for a set of customizations that can be associated with any Map ID.
To create a new style:
In the Google Cloud Console, go to the Map Styles page.
Click Create New Map Style to open the New Map Style page.
In the New Map Style page, choose one of the following options:
- Select a Map Style from one of the available style variations.
- Import JSON styling code by pasting your JSON code into the text box on the Import JSON tab.
- Select a Map Style customized to emphasize the goals of a specific industry, such as Travel, Logistics, Real Estate, and Retail.
You can specify additional customizations to map features by clicking Customize in Style Editor. For more information, see Using the style editor.
To name your Map Style and save your changes, click Save.
Updating style details
On the Map Styles page, you can select a map style to complete the following actions:
Continue customizing or view style details in the Style Editor by clicking Customize style. For more information, see Using the style editor.
Rename or edit a description for the style by clicking Edit.
Duplicate the style by clicking Duplicate.
Delete the style by clicking Delete.
View Map IDs associated with the style.
Styles created before September 15, 2020 will not display Google Maps enhanced natural features. To use Google Maps enhanced natural features support for your map styling, you must create a Map Style.
Optional Cloud Styling CocoaPod or GitHub demo
Instead of starting from scratch, you can try out our Maps customization demo, which is installed by following the instructions in the Using the Google Maps Beta CocoaPod section.
Alternatively, you can find an Objective-C sample application that demonstrates how to style your iOS map from the cloud here.
Building the Beta demo app
In Xcode, press the compile button to build and then run the current scheme.
The build produces an error, prompting you to enter your API key in the
If you don't yet have an API key, follow the instructions
to set up a project on the Cloud Console and get an API key. When
configuring the key on the Cloud Console, you can specify your app's
bundle identifier to ensure that only your app can use the key. The default
bundle identifier of the SDK samples app is
SDKDemoAPIKey.h file and paste your API key into the definition
of the kAPIKey constant:
static NSString *const kAPIKey = @"YOUR_API_KEY";
If Xcode prompts you to unlock the SDKDemoAPIKey.h file for editing, choose Unlock.
Remove the following line:
#error Register for API Key and insert here.
Build and run the project.
Maps customization map demo
CloudStyling demo shows how to style the map by using a style set on Google Cloud Console.
When the demo application launches, click on the Map Customization demo in the Beta Samples section at the top of the list.
Click on Style Map to see the effect of loading different Map IDs.
You can try adding your own style as well ("Style Map" > "Add a new Map ID"), and see the map update with your custom styled map.
