MLNPointAnnotation class

An MLNPointAnnotation object represents a one-dimensional shape located at a single geographical coordinate. Depending on how it is used, an MLNPointAnnotation 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 MLNShapeSource object. Configure the appearance of an MLNShapeSource’s or MLNVectorTileSource’s point shapes collectively using an MLNVectorTileSource or MLNSymbolStyleLayer object.

For more interactivity, add a selectable point annotation to a map view using the MLNMapView/addAnnotation: method. Alternatively, define your own model class that conforms to the MLNAnnotation protocol. Configure a point annotation’s appearance using MLNMapViewDelegate/mapView:imageForAnnotation: or MLNMapViewDelegate/mapView:viewForAnnotation: (iOS only). A point annotation’s MLNShape/title and MLNShape/title 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 MLNPointCollection or MLNPointCollection object. To access a point’s attributes, use an MLNPointFeature object.

A point shape is known as a Point geometry in GeoJSON.
