AI-generated Key Takeaways

• GMSNavigationDirectionsListController manages and displays a directions list, updating automatically based on an associated navigator's state.

• The directionsListView property provides access to the view displaying the directions, but it's lazy-loaded upon first access.

• This controller is initialized with a GMSNavigator instance which drives the list's content and updates.

• reloadData and invalidateLayout methods allow for manual refreshing of the list data and layout, respectively, but are ineffective before the directionsListView is accessed.

• Direct initialization using init is unavailable; instead, use initWithNavigator: to provide the necessary navigator instance.

GMSNavigationDirectionsListController

@interface GMSNavigationDirectionsListController : NSObject

A controller that manages and displays a directions list. The controller maintains its own states internally based on the associated navigator. The directionsListView is updated automatically based on navigator states.

• directionsListView

  The view that displays the directions list. The view is lazy loaded when it is accessed for the first time.

  Declaration

  Swift

  var directionsListView: UIView { get }

  Objective-C

  @property (nonatomic, readonly) UIView *_Nonnull directionsListView;

• -initWithNavigator:

  Initializes the controller with a navigator.

  Declaration

  Swift

  init(navigator: GMSNavigator)

  Objective-C

  - (nonnull instancetype)initWithNavigator:(nonnull GMSNavigator *)navigator;

  Parameters

  navigator

  The controller automatically updates the list based on the current state of the navigator after directionsListView is accessed for the first time.

• -reloadData

  Updates the data source from the latest navigator state and reload the list. Calling this method before directionsListView is accessed for the first time results in no-op.

  Declaration

  Swift

  func reloadData()

  Objective-C

  - (void)reloadData;

• -invalidateLayout

  Invalidates the layout of the directionsListView. This should be called during events such as rotations and view size changes. Calling this method before directionsListView is accessed for the first time results in no-op.

  Declaration

  Swift

  func invalidateLayout()

  Objective-C

  - (void)invalidateLayout;

• -init

  Unavailable

  Use -initWithNavigator: instead.

  Declaration

  Objective-C

  - (null_unspecified instancetype)init;
