ios - 如何通过 Swift 使用 GPS 坐标在 map 上添加多个注释？

Question

我是 Swift 新手。我正在按照教程在 map 上进行注释。我成功地做了一个注释，这就是本教程的内容...我一直在寻找如何使用 Swift 进行多个注释，但找不到它。

如何在 map 上进行多个注释？谢谢。

这是我来自 viewcontroller.swift 的代码:

import UIKit
import MapKit

class ViewController: UIViewController, MKMapViewDelegate {

    @IBOutlet var map: MKMapView!  
    override func viewDidLoad() {
        super.viewDidLoad()


        //setting the map region
        let latitude: CLLocationDegrees = 33.606800
        let longitude: CLLocationDegrees = -111.845360
        let latDelta: CLLocationDegrees = 0.01
        let lonDelta: CLLocationDegrees = 0.01
        let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
        let location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)
        map.setRegion(region, animated: true)

        //map annotation
        let annotation = MKPointAnnotation()
        annotation.coordinate = location
        annotation.title = "Taliesin West"
        annotation.subtitle = "Design"
        map.addAnnotation(annotation)        

        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

只需像示例一样创建另一个注释并调用

map.addAnnotation(another)
