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.
-
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;
-
Initializes the controller with a navigator.
Declaration
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.
|
-
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
Objective-C
- (void)reloadData;
-
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;
-
Declaration
Objective-C
- (null_unspecified instancetype)init;
