MapKit地图 - 注释上的模拟器

Question

不显示我试图显示标志物的MapView同时加载，但在地图中显示我的countrymap中的MapView但不是注释。我在做什么错事？仅供参考，我的模拟器位置设置为Apple。

import MapKit 
import UIKit 

class Capital: NSObject, MKAnnotation { 
    var title: String? 
    var coordinate: CLLocationCoordinate2D 
    var info: String 

    init(title: String, coordinate: CLLocationCoordinate2D, info: String) { 
     self.title = title 
     self.coordinate = coordinate 
     self.info = info 
    } 
} 





import MapKit 
import UIKit 

class ViewController: UIViewController, MKMapViewDelegate { 
    @IBOutlet weak var mapView: MKMapView! 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     let london = Capital(title: "London", coordinate: CLLocationCoordinate2D(latitude: 51.507222, longitude: -0.1275), info: "Home to the 2012 Summer Olympics.") 
     let oslo = Capital(title: "Oslo", coordinate: CLLocationCoordinate2D(latitude: 59.95, longitude: 10.75), info: "Founded over a thousand years ago.") 
     let paris = Capital(title: "Paris", coordinate: CLLocationCoordinate2D(latitude: 48.8567, longitude: 2.3508), info: "Often called the City of Light.") 
     let rome = Capital(title: "Rome", coordinate: CLLocationCoordinate2D(latitude: 41.9, longitude: 12.5), info: "Has a whole country inside it.") 
     let washington = Capital(title: "Washington DC", coordinate: CLLocationCoordinate2D(latitude: 38.895111, longitude: -77.036667), info: "Named after George himself.") 

     mapView.addAnnotations([london, oslo, paris, rome, washington]) 
    } 
} 

Answer 1

尝试这个

import UIKit 
import MapKit 



class MapViewController: UIViewController { 
     @IBOutlet var mapView: MKMapView! 

     let location:CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 20.5937, longitude: 78.9629) 


     override func viewDidLoad() { 
      super.viewDidLoad() 



      let anotation = MKPointAnnotation() 
      anotation.coordinate = location 
      anotation.title = "The Location" 
      anotation.subtitle = "This is the location !!!" 
      mapView.addAnnotation(anotation) 

     } 
}
