如何在地图上显示标注点信息?
How can I show the annotation point information on the map?
当我点击地图上的注释时,我希望点击位置的信息出现在 bottom.I 使用 Mapkit 创建地图的后视图中
注释数组
let annotationLocations = [
["title":"X vet Clinic","latitude":39.895177 , "longitude":32.838194],
["title":"Y Vet Clinic","latitude": 39.894749, "longitude":32.841074],
["title":"Z Vet Clinic","latitude": 39.893615, "longitude":32.841476]
]
有了这个功能,我可以在地图上显示上面经纬度指定的位置
func createAnnotations(locations: [[String: Any]])
{
for location in locations{
let annotations = MKPointAnnotation()
annotations.title = location["title"] as? String
annotations.coordinate = CLLocationCoordinate2D(latitude: location["latitude"] as! CLLocationDegrees, longitude: location["longitude"] as! CLLocationDegrees)
myMap.addAnnotation(annotations)
}
}
首先设置委托
myMap.delegate = self
然后实施
func mapView(_ mapView: MKMapView,didSelect view: MKAnnotationView) {
let ann = view.annotation as! MKPointAnnotation
// use ann
}
您可以将注释子类化并将所需数据放入其中;
class VetClinicAnnotation: MKPointAnnotation {
let name: String
let address: String
let image: UIImage
init(with name: String, address: String, image: UIImage) {
self.name = name
self.address = address
self.image = image
}
}
然后您可以从您的地图视图委托中获取注释信息;
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
if let annotation = view.annotation as? VetClinicAnnotation {
// Use the annotation data
}
}
