Cluster is an easy map annotation clustering library. This repository uses an efficient method (QuadTree) to aggregate pins into a cluster.
You may want to see the Example first if you'd like to see the actual code.
$ pod try Cluster
Requirements
- iOS 8.0+
- Xcode 8.0+
- Swift 3.0+
Usage
Follow the instructions below:
Step 1: Initialize a ClusterManager object
let clusterManager = ClusterManager()Step 2: Add annotations
let annotation = Annotation()
annotation.coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
annotation.type = .color(color, radius: 25) // .image(UIImage(named: "pin"))
clusterManager.add(annotation)Step 3: Return the pins and clusters
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
var view = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
if view == nil {
view = ClusterAnnotationView(annotation: annotation, reuseIdentifier: identifier, type: type)
} else {
view?.annotation = annotation
}
return view
}Step 4: Reload the annotations
func mapView(_ mapView: MKMapView, regionDidChangeAnimated animated: Bool) {
clusterManager.reload(mapView, visibleMapRect: mapView.visibleMapRect)
