我想用personnal coordonate更改地图的位置。 (当我说“personnal”时,不是“用户位置”,而只是随机的coordonate)。
这是我的MapView控制器:
class MapSubViewController: UIViewController {
@IBOutlet weak var mapView: MKMapView!
let regionRadius: CLLocationDistance = 1000
override func viewDidLoad() {
super.viewDidLoad()
self.mapLocationUpdate(70.0, longitude: 70.0, title: "")
}
func mapLocationUpdate(latitude: Double, longitude: Double, title: String) {
let location = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
self.centerMapOnLocation(location, title: title)
}
func centerMapOnLocation(location: CLLocationCoordinate2D, title: String) {
let coordinateRegion = MKCoordinateRegion(center: location, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
self.mapView.setRegion(coordinateRegion, animated: false)
let annotation = MKPointAnnotation()
annotation.coordinate = location
annotation.title = title
self.mapView.addAnnotation(annotation)
}
}
当我想要更改地图的位置时,我告诉我的函数“mapLocationUpdate”:
例如:
func addMapView(xPosition: Double, yPosition: Double, title: String) {
self.mapSubViewController = (self.storyboard!.instantiateViewControllerWithIdentifier("MapSubViewController") as? MapSubViewController)!
self.mapSubViewController.mapLocationUpdate(xPosition, longitude: yPosition, title: clubName)
[...]
}
当执行“self.mapSubViewController.mapLocationUpdate(...)”行时,我的应用程序崩溃。当它是告诉函数“mapLocationUpdate”的控制器的“viewDidLoad”时,应用程序不会崩溃。
我认为这是因为地图收费后代码中的地图位置无法更改。
我该怎么做?
对不起我的英语,我尽我所能:-)!
Thx!

要在地图上设置自定义位置,您应该使用与此类似的内容:
let pLat = 43.6109200
let pLong = 3.8772300
let center = CLLocationCoordinate2D(latitude: pLat, longitude: pLong)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
self.mapView.setRegion(region, animated: true)
