GoogleNavigation Framework Reference

  • This documentation details globally available protocols for the Maps SDK for iOS.

  • These protocols define delegates and listeners for handling events and interactions within the map environment.

  • They cover areas such as navigation UI, custom views, screen metrics, and location updates.

  • Developers can use these protocols to customize map behavior and respond to user actions.

  • Protocols are available for features like indoor maps, panoramic views, and tile layers.

Protocols

The following protocols are available globally.

  • A delegate for events on GMSMapView related to the navigation UI.

    Declaration

    Swift

    protocol GMSMapViewNavigationUIDelegate : NSObjectProtocol

    Objective-C

    @protocol GMSMapViewNavigationUIDelegate <NSObject>

  • Protocol defining methods that support custom views specifying accessory UI elements applied to the primary view. Accessory views must implement this protocol in order to be visible.

    Declaration

    Swift

    protocol GMSNavigationAccessoryView : NSObjectProtocol

    Objective-C

    @protocol GMSNavigationAccessoryView <NSObject>

  • Protocol for returning information about screen metrics.

    This protocol is a subset of the screen-metric-related properties implemented by UIScreen.

    Declaration

    Swift

    protocol GMSNavigationScreenMetrics

    Objective-C

    @protocol GMSNavigationScreenMetrics

  • Listener for events on GMSNavigator.

    Declaration

    Swift

    protocol GMSNavigatorListener : NSObjectProtocol

    Objective-C

    @protocol GMSNavigatorListener <NSObject>

  • Listener for events on GMSRoadSnappedLocationProvider.

    Declaration

    Swift

    protocol GMSRoadSnappedLocationProviderListener : NSObjectProtocol

    Objective-C

    @protocol GMSRoadSnappedLocationProviderListener <NSObject>

  • An interface representing a feature’s metadata.

    Do not save a reference to a particular feature object because the reference will not be stable.

    Declaration

    Swift

    protocol Feature : NSObjectProtocol

    Objective-C

    @protocol GMSFeature <NSObject>

  • Delegate for events on GMSIndoorDisplay.

    Declaration

    Swift

    protocol GMSIndoorDisplayDelegate : NSObjectProtocol

    Objective-C

    @protocol GMSIndoorDisplayDelegate <NSObject>

  • Delegate for events on GMSMapView.

    Declaration

    Swift

    protocol GMSMapViewDelegate : NSObjectProtocol

    Objective-C

    @protocol GMSMapViewDelegate <NSObject>

  • Delegate for events on GMSPanoramaView.

    Declaration

    Swift

    protocol GMSPanoramaViewDelegate : NSObjectProtocol

    Objective-C

    @protocol GMSPanoramaViewDelegate <NSObject>

  • GMSTileReceiver is provided to GMSTileLayer when a tile request is made, allowing the callback to be later (or immediately) invoked.

    Declaration

    Swift

    protocol GMSTileReceiver : NSObjectProtocol

    Objective-C

    @protocol GMSTileReceiver <NSObject>
