GoogleNavigation Framework Reference

  • This documentation details globally available constants used within the Google Maps SDK for iOS.

  • Constants are provided for various map features like zoom levels, accessibility identifiers, feature types, and camera properties.

  • Developers can utilize these constants to customize and control different aspects of the map's behavior and appearance.

  • Constants are defined for both Swift and Objective-C, ensuring compatibility across different development environments.

  • These constants provide essential values for working with map layers, markers, ground overlays, and panoramas, enabling developers to fine-tune the user experience.

Constants

The following constants are available globally.

  • The value used to clear the followingZoomLevel, and reset the camera to adopt the default zoom behavior.
