GMSMapViewNavigationLayout

@protocol GMSMapViewNavigationLayout;

Protocol for an object that hosts the layoutDelegate property, adopted by the NavigationLayout category of GMSMapView.

• layoutDelegate

  The layout delegate for the map view.

  The map view will hold a strong reference to the layout delegate. The layout delegate may be set to nil, which will mean NavSDK’s built-in layout code which implements the deprecated layout APIs will be used.

  Declaration

  Swift

  var layoutDelegate: (any NavigationLayoutDelegate)? { get }

  Objective-C

  @property (nonatomic, readonly, nullable) id<GMSNavigationLayoutDelegate> layoutDelegate;

• -setLayoutDelegate:error:

  Sets the layout delegate for the map view.

  This method may only be called before the navigation UI is enabled and cannot be called on a map view initialized on a CarPlay screen. If invoked after navigation UI has been enabled or on a CarPlay screen, throws an error (returns NO and populates the error in Objective-C).

  Declaration

  Swift

  func setLayoutDelegate(_ layoutDelegate: (any NavigationLayoutDelegate)?) throws

  Objective-C

  - (BOOL)setLayoutDelegate:
              (nullable id<GMSNavigationLayoutDelegate>)layoutDelegate
                      error:(NSError *_Nullable *_Nullable)error;

  Parameters

  layoutDelegate

  The layout delegate to set, or nil to use the built-in layout code.
