Do any additional setup after loading the view, typically from a nib. Complete Example.Ĭlass ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate weak var mapView: MKMapView! MapKit scales images that are larger or smaller than those sizes. Let pinImage = UIImage(named: "customPinImage")ĭisplay Custom Pin Image for MKAnnotationView. A deselected annotation is marked by a pin image. ![]() Var annotationView = queueReusableAnnotationViewWithIdentifier(annotationIdentifier)ĪnnotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier) Let annotationIdentifier = "AnnotationIdentifier" Optional public func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView?īelow is a very simple example of how you can do it:įunc mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? To customize MapView annotations you will need to make your ViewController conform to a MKMapViewDelegate protocol and implement the following function: Create MKAnnotationView with custom imageĬreate MKAnnotationView with custom image.Drop MKPointAnnotation as a Pin at user’s current location.Create MKPointAnnotation with custom title.Finally we add source and layer created in previous steps to the style.This Swift code example will demonstrate how to add custom image to a MKAnnotationView.Next we load the image and register it a style sprite.Use the more common extended objects, mapkit.Marker Annotation and mapkit.Image Annotation instead. It’s rare that you need to create a mapkit.Annotation object. Associate each annotation with a coordinate on the map. Then we create the MGLShapeSource with shape being the annotation created in previous step and MGLSymbolStyleLayer to show the shape from the source on the map. An annotation represents data that you want to display on the map’s surface.We create MGLPointAnnotation and set its coordinate to the center of the screen.-mapView:annotationCanShowCallout: returns a boolean value indicating whether the annotation can display additional information inside a callout.-mapView:didSelectAnnotation: is called when an annotation is tapped on.-mapView:imageForAnnotation: returns an MGLAnnotationImage that can associate a UIImage with a specific MGLPointAnnotation.-mapView:viewForAnnotation: returns an MGLAnnotationView that can associate a UIView with a specific MGLPointAnnotation.Commonly implemented delegate methods include: new mapkit.ImageAnnotation( mapkit. An annotation view that displays a pin image on the map. Creates an image annotation with a URL to its image and a coordinate. An annotation view that displays a balloon-shaped marker at the designated location. If your project includes those requirements, consider using our more performant MGLStyleLayer classes.Īny MGLPointAnnotation, MGLLine, or MGLPolygon that conforms to the MGLAnnotation protocol can be used to annotate the map to mark a place with a specific shape.īy implementing optional MGLMapViewDelegate, you can customize the basic styling of annotations. Annotate a map with location-specific data using default and customized annotation views and callouts. But using annotations is not recommended if you need to add a large number of markers to a map, or if you also need to style annotations differently based on a specific data property. It has built-in dragging and selection support. View complete source code on GitHub AnnotationsĪnnotations provide an interface that will look familiar if you’ve used annotations in MapKit. ![]() How to display marker on the map using annotations.This example demonstrates how to use annotations to display marker on the map.
