为什么地图点未显示在mapKitView中？

2024-05-16 • 问答

我在这里尝试在MKMapView中显示乘数位，但未显示

import MapKit

@IBOutlet weak var mapView: MKMapView!

 let locations = [
    ["title": "New York,NY","latitude": 40.713054,"longitude": -74.007228],["title": "Los Angeles,CA","latitude": 34.052238,"longitude": -118.243344],["title": "Chicago,IL","latitude": 41.883229,"longitude": -87.632398]
]


 override func viewDidLoad()
{
for location in locations {
    let annotation = MKPointAnnotation()
    annotation.title = location["title"] as? String
    annotation.coordinate = CLLocationCoordinate2D(latitude: location["latitude"] as! Double,longitude: location["longitude"] as! Double)
    mapView.addAnnotation(annotation)
}
}

我的地图正在显示默认的印度地图。

缩放

 mapView.addAnnotation(annotation)
 mapView.showAnnotations(mapview.annotations,animated:true)

顺便说一句，想起一个模型

struct Item {
  let title:String
  let latitude,longitude:Double
}

ios mkmapview swift
