MGLMultiPolyline
@interface MGLMultiPolyline : MGLShape <MGLOverlay>
An MGLMultiPolyline
object represents a shape consisting of one or more
polylines. For example, you could use a multipolyline shape to represent both
sides of a divided highway (dual carriageway), excluding the median (central
reservation): each carriageway would be a distinct MGLPolyline
object.
You can add multipolyline shapes to the map by adding them to an
MGLShapeSource
object. Configure the appearance of an MGLShapeSource
’s or
MGLVectorSource
’s multipolylines collectively using an MGLLineStyleLayer
or
MGLSymbolStyleLayer
object.
You cannot add an MGLMultiPolyline
object directly to a map view using
-[MGLMapView addAnnotation:]
or -[MGLMapView addOverlay:]
. However, you can
add the polylines
array’s items as overlays individually.
A multipolyline is known as a MultiLineString geometry in GeoJSON.
-
An array of polygons forming the multipolyline.
