MGLSource


@interface MGLSource : NSObject

MGLSource is an abstract base class for map content sources. A map content source supplies content to be shown on the map. A source is added to an MGLStyle object along with an MGLForegroundStyleLayer object. The foreground style layer defines the appearance of any content supplied by the source.

Each source defined by the style JSON file is represented at runtime by an MGLSource object that you can use to refine the map’s content. You can also add and remove sources dynamically using methods such as -[MGLStyle addSource:] and -[MGLStyle sourceWithIdentifier:].

Create instances of MGLShapeSource, MGLImageSource and the concrete subclasses of MGLTileSource (MGLVectorSource and MGLRasterSource) in order to use MGLSource‘s properties and methods. Do not create instances of MGLSource directly, and do not create your own subclasses of this class.

  • Returns a source initialized with an identifier.

    After initializing and configuring the source, add it to a map view’s style using the -[MGLStyle addSource:] method.
