MGLPointAnnotation
@interface MGLPointAnnotation : MGLShape
An MGLPointAnnotation
object represents a one-dimensional shape located at a
single geographical coordinate. Depending on how it is used, an
MGLPointAnnotation
object is known as a point annotation or point shape. For
example, you could use a point shape to represent a city at low zoom levels, an
address at high zoom levels, or the location of a long press gesture.
You can add point shapes to the map by adding them to an MGLShapeSource
object. Configure the appearance of an MGLShapeSource
’s or
MGLVectorSource
’s point shapes collectively using an MGLCircleStyleLayer
or
MGLSymbolStyleLayer
object.
For more interactivity, add a selectable point annotation to a map view using
the -[MGLMapView addAnnotation:]
method. Alternatively, define your own model
class that conforms to the MGLAnnotation
protocol. Configure a point
annotation’s appearance using
-[MGLMapViewDelegate mapView:imageForAnnotation:]
or
-[MGLMapViewDelegate mapView:viewForAnnotation:]
(iOS only). A point
annotation’s MGLShape.title
and MGLShape.subtitle
properties define the
default content of the annotation’s callout (on iOS) or popover (on macOS).
To group multiple related points together in one shape, use an
MGLPointCollection
or MGLShapeCollection
object.
A point shape is known as a Point geometry in GeoJSON.
-
The coordinate point of the shape, specified as a latitude and longitude.
