如何在地图上显示注释点信息？

如何解决如何在地图上显示注释点信息？

当我点击地图上的 Annotation 时，我希望点击位置的信息出现在底部的后视图中。我使用 Mapkit 创建地图

注解数组

  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]
      
    ]

通过这个功能，我可以在地图上显示上面纬度经度中指定的位置

 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)
            
        }
       
        
    }

解决方法

先设置委托

myMap.delegate = self

然后执行

func mapView(_ mapView: MKMapView,didSelect view: MKAnnotationView) {
   let ann = view.annotation as! MKPointAnnotation
   // use ann
}

,

您可以对注释进行子类化并将所需的数据放入其中；

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
    }
    
}
