Style Layers

A map style’s background layer is the bottommost layer and is used to style a color or pattern to show below all other map features. You can query an MGLMapView for its style and obtain the background layer using the -[MGLStyle layerWithIdentifier:] method and passing background for the identifier.

A circle layer which allows customization of styling properties at runtime. You may instantiate a new circle layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.

A fill layer which allows customization of styling properties at runtime. You may instantiate a new fill layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.

MGLForegroundStyleLayer is an abstract superclass for style layers whose content is defined by an MGLSource object.

Do not create instances of this class directly, and do not create your own subclasses of this class. Instead, create instances of MGLRasterStyleLayer and the concrete subclasses of MGLVectorStyleLayer.

A line layer which allows customization of styling properties at runtime. You may instantiate a new line layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.

A raster layer which allows customization of styling properties at runtime. You may instantiate a new raster layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.

MGLStyleLayer 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 MGLStyle object consists of one or more MGLStyleLayer objects.

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

Do not create instances of this class directly, and do not create your own subclasses of this class. Instead, create instances of MGLBackgroundStyleLayer and the concrete subclasses of MGLForegroundStyleLayer.

A symbol layer which allows customization of styling properties at runtime. You may instantiate a new symbol layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.

MGLVectorStyleLayer is an abstract superclass for style layers whose content is defined by an MGLGeoJSONSource or MGLVectorSource object.

Do not create instances of this class directly, and do not create your own subclasses of this class. Instead, create instances of the following concrete subclasses: MGLCircleStyleLayer, MGLFillStyleLayer, MGLLineStyleLayer, and MGLSymbolStyleLayer.
