这是我第一次在这里发帖.我目前陷入困境,试图找出如何在我的地图上添加一个按钮,如果他们在地图上偏离它,将重新显示用户的当前位置.目前我有下面写的代码显示用户的当前位置.

    import UIKit
    import MapKit
    import CoreLocation

   class GameViewController: UIViewController,CLLocationManagerDelegate
   {

var lastUserLocation: MKUserLocation?





@IBOutlet weak var Map: MKMapView!

let manager = CLLocationManager()





func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations[0]

    let span:MKCoordinateSpan = MKCoordinateSpanMake(0.00775, 0.00775)

    let myLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude,location.coordinate.longitude)

    let region: MKCoordinateRegion = MKCoordinateRegionMake(myLocation, span)
    Map.setRegion(region, animated: true)


    self.Map.showsUserLocation = true
    manager.stopUpdatingLocation()


}



override func viewDidLoad() {
    super.viewDidLoad()
    manager.delegate = self
    manager.desiredAccuracy = kCLLocationAccuracyBest
    manager.requestAlwaysAuthorization()
    manager.startUpdatingLocation()




}

@IBAction func refLocation(_ sender: Any) {
    print("click") …

我想说它只是从我的阅读和理解来看是服务器端的，但我希望得到一些澄清。谢谢。
