Map Data

  • The MGLFeature protocol is used to provide details about geographic features contained in a map view’s tile sources. Each concrete subclass of MGLShape in turn has a subclass that conforms to this protocol.

    Typically, you do not create feature objects yourself but rather obtain them using -[MGLMapView visibleFeaturesAtPoint:] and related methods. Each feature object associates a shape with an identifier and attributes as specified by the source. Like ordinary MGLAnnotation objects, some kinds of MGLFeature objects can also be added to a map view using -[MGLMapView addAnnotations:] and related methods.
