Question

我目前正在开发一款iOS应用程序，其中一项功能包括定位夜生活场所。但是，当我的MapView加载时，即使已授予位置访问权限，也不会显示当前用户位置。

这是我的代码：

import UIKit
import MapKit
import CoreLocation

class BarMapVC: UIViewController {



@IBOutlet weak var searchBtn: UIBarButtonItem!

@IBOutlet weak var doneBtn: UIBarButtonItem!

@IBOutlet weak var searchBar: UISearchBar!

@IBOutlet weak var locationBtn: UIButton!

@IBOutlet weak var barMapView: MKMapView!

var locationManager = CLLocationManager()
let authorizationStatus = CLLocationManager.authorizationStatus()
let regionRadius: Double = 1000

override func viewDidLoad() {
    super.viewDidLoad()
    searchBar.isHidden = true
    barMapView.delegate = self
    locationManager.delegate = self
    configureLocationServices()
    centerMapOnUserLocation()
}

@IBAction func searchBtnWasPressed(_ sender: Any) {
    searchBar.isHidden = false
}

@IBAction func doneBtnWasPressed(_ sender: Any) {
    dismiss(animated: true)
}

@IBAction func locationBtnWasPressed(_ sender: Any) {
    if authorizationStatus == .authorizedAlways || authorizationStatus == .authorizedWhenInUse {
        centerMapOnUserLocation()
    }
}
}

extension BarMapVC: MKMapViewDelegate {
    func centerMapOnUserLocation() {
        guard let coordinate = locationManager.location?.coordinate else { return }
        let coordinateRegion = MKCoordinateRegionMakeWithDistance(coordinate, regionRadius * 2.0, regionRadius * 2.0)
        barMapView.setRegion(coordinateRegion, animated: true)
    }
}

extension BarMapVC: CLLocationManagerDelegate {
    func configureLocationServices() {
        if authorizationStatus == .notDetermined {
            locationManager.requestAlwaysAuthorization()
        } else {
            return
        }
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        centerMapOnUserLocation()
    }

}

我正在使用CLLocation Manager，符合mapViewDelegate，以及所有需要的插座。我做错了什么？

您可以在地图视图中进行设置：

barMapView.showsUserLocation = true

MapView不显示位置
