Yandex MapKit iOS : cluster and placemarks
问题
我正在使用Yandex Mapkit iOS SDK进行我的一个项目。
看来SDK允许将地标添加到一个集群中。但是我无法像添加一个mapObject
一样添加一个带有userData
的自定义地标。我想要检测标记上的点击操作。
// 将标记添加为mapobjects:
let point = YMKPoint(coordinate: CLLocationCoordinate2D(latitude: Double(hit.geom!.lat ?? 0), longitude: Double(hit.geom?.lon ?? 0)))
let placemark: YMKPlacemarkMapObject
self.mapObjects = self.mapView.mapWindow.map.mapObjects
placemark = mapObjects!.addPlacemark(with: point, image: #imageLiteral(resourceName: "marker"))
placemark.userData = MarkerUserData(id: Int(hit.id!)!, description: hit.plate!)
placemark.isDraggable = false
placemark.addTapListener(with: self)
mapObjects!.addListener(with: self)
在一个集群中添加标记,标记可以使用只有YMKPoint
的方式添加到集群中。我找不到一种在集群中添加placemark
对象的方法。
let point = YMKPoint(coordinate: CLLocationCoordinate2D(latitude: Double(hit.geom!.lat ?? 0), longitude: Double(hit.geom?.lon ?? 0)))
let placemark: YMKPlacemarkMapObject
collection.addPlacemark(with: point, image: #imageLiteral(resourceName: "marker"))
// 直到调用这个方法之前,标记才会显示出来。它必须在集合更改后强制调用以更新集群
collection.clusterPlacemarks(withClusterRadius: 20, minZoom: 5)

I am using Yandex Mapkit iOS SDK for one of my projects.
It seems that SDK allows adding placemarks is a cluster. Bu I can not add a custom place mark with userData as the same way adding a placemark as a mapObject
. I want to detect tap action on a marker.
// adding markers as mapobjects:
let point = YMKPoint(coordinate: CLLocationCoordinate2D(latitude: Double(hit.geom!.lat ?? 0), longitude: Double(hit.geom?.lon ?? 0)))
let placemark: YMKPlacemarkMapObject
self.mapObjects = self.mapView.mapWindow.map.mapObjects
placemark = mapObjects!.addPlacemark(with: point, image: #imageLiteral(resourceName: "marker"))
placemark.userData = MarkerUserData(id: Int(hit.id!)!, description: hit.plate!)
placemark.isDraggable = false
placemark.addTapListener(with: self)
mapObjects!.addListener(with: self)
Adding markers in a cluster, markers can be added to a cluster using only YMKPoint
. I could not find a way to add a placemark
object inside a cluster
let point = YMKPoint(coordinate: CLLocationCoordinate2D(latitude: Double(hit.geom!.lat ?? 0), longitude: Double(hit.geom?.lon ?? 0)))
let placemark: YMKPlacemarkMapObject
collection.addPlacemark(with: point, image: #imageLiteral(resourceName: "marker"))
// Placemarks won't be displayed until this method is called. It must be also called
// to force clusters update after collection change
collection.clusterPlacemarks(withClusterRadius: 20, minZoom: 5)

定义一个带有监听器的集合。用任意点填充数组。遍历数组并将每个点添加到集合中。当将点添加到集合时,返回YMKPlacemarkMapObject,添加用户数据。并扩展您的控制器委托方法。
并查看带有Yandex的测试项目 - https://github.com/yandex/mapkit-ios-demo/blob/master/MapKitDemo/ClusteringViewController.swift
class MapViewController: UIViewController {
@IBOutlet weak var mapView: YMKMapView!
var collection: YMKClusterizedPlacemarkCollection?
var points: [YMKPoint] = [] // 用任意点填充数组
override func viewDidLoad() {
super.viewDidLoad()
collection = mapView.mapWindow.map.mapObjects.addClusterizedPlacemarkCollection(with: self)
collection?.addTapListener(with: self)
for point in points {
let placemark = collection?.addPlacemark(with: point,
image: UIImage(named: "some_image")!,
style: YMKIconStyle.init())
placemark?.userData = "用户数据"
}
collection.clusterPlacemarks(withClusterRadius: 60, minZoom: 15)
}
}
extension MapViewController: YMKMapObjectTapListener {
func onMapObjectTap(with mapObject: YMKMapObject, point: YMKPoint) -> Bool {
guard let userPoint = mapObject as? YMKPlacemarkMapObject else {
return true
}
print(userPoint.userData)
}
}
请注意,上述代码是一个Swift类的示例,用于在地图上添加点并进行聚类。如果需要更多帮助或有其他问题,请随时提问。

Define a collection with a listener. Fill the array with any points. Go through the array and add each point to the collection. When adding a point to the collection, YMKPlacemarkMapObject is returned, adding user data. And extend your controller delegate method.
And look at the test project with Yandex - https://github.com/yandex/mapkit-ios-demo/blob/master/MapKitDemo/ClusteringViewController.swift
class MapViewController: UIViewController {
@IBOutlet weak var mapView: YMKMapView!
var collection: YMKClusterizedPlacemarkCollection?
var point: [YMKPoint] = [] // Fill the array with any points
override func viewDidLoad() {
super.viewDidLoad()
collection = mapView.mapWindow.map.mapObjects.addClusterizedPlacemarkCollection(with: self)
collection?.addTapListener(with: self)
for point in points {
let placemark = collection?.addPlacemark(with: point,
image: UIImage(named: "some_image")!,
style: YMKIconStyle.init())
placemark?.userData = "user data"
}
collection.clusterPlacemarks(withClusterRadius: 60, minZoom: 15)
}
}
extension MapViewController: YMKMapObjectTapListener {
func onMapObjectTap(with mapObject: YMKMapObject, point: YMKPoint) -> Bool {
guard let userPoint = mapObject as? YMKPlacemarkMapObject else {
return true
}
print(userPoint.userData)
}
}
