DingiStyleLayer

 

@interface DingiStyleLayer : NSObject

DingiStyleLayer is an abstract base class for style layers. A style layer manages the layout and appearance of content at a specific z-index in a style. An DingiStyle object consists of one or more DingiStyleLayer objects.

Each style layer defined by the style JSON file is represented at runtime by an DingiStyleLayer object, which you can use to refine the map’s appearance. You can also add and remove style layers dynamically.

Create instances of DingiBackgroundStyleLayer and the concrete subclasses of DingiForegroundStyleLayer in order to use DingiStyleLayer‘s properties and methods. You do not create instances of DingiStyleLayer directly, and do not create your own subclasses of this class.

Do not add DingiStyleLayer objects to the style property of a DingiMapView before -mapView:didFinishLoadingStyle: is called.

Identifying a Style Layer

  • A string that uniquely identifies the style layer in the style to which it is added.

    Declaration

    Objective-C

    @property (readonly, copy, nonatomic) NSString *_Nonnull identifier;

    Swift

    var identifier: String { get }

Configuring a Style Layer’s Visibility

  • Whether this layer is displayed. A value of NO hides the layer.

    Declaration

    Objective-C

    @property (getter=isVisible, assign, readwrite, nonatomic) BOOL visible;

    Swift

    var isVisible: Bool { get set }

  • The maximum zoom level at which the layer gets parsed and appears. This value is a floating-point number.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) float maximumZoomLevel;

    Swift

    var maximumZoomLevel: Float { get set }

  • The minimum zoom level at which the layer gets parsed and appears. This value is a floating-point number.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) float minimumZoomLevel;

    Swift

    var minimumZoomLevel: Float { get set }
