Swift用户位置问题

Question

我在项目开始时就在用户位置上工作mapview，但现在它不会在启动时放大用户。知道怎么解决这个问题吗?我使用的代码:

在课堂上

  class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate
  var Locationmanager = CLLocationManager()

在viewdidload

    self.Locationmanager.delegate = self
    self.Locationmanager.desiredAccuracy = kCLLocationAccuracyBest
    self.Locationmanager.requestWhenInUseAuthorization()
    self.Locationmanager.startUpdatingLocation()
    self.Mapview.showsUserLocation = true
    Mapview.setCenterCoordinate(Mapview.userLocation.coordinate, animated: true)

在功能上

      func locationManager(manager: CLLocationManager, didUpdateLocations locations:[MKUserLocation]) {
      let latitude = Locationmanager.location?.coordinate.latitude
      let longitude = Locationmanager.location?.coordinate.longitude
      let center = CLLocationCoordinate2D (latitude: latitude!, longitude: longitude!)
      let region = MKCoordinateRegion (center: center, span: MKCoordinateSpan (latitudeDelta: 0.02, longitudeDelta: 0.02))
      self.Mapview.setRegion(region, animated: true)
      self.Locationmanager.stopUpdatingLocation()

和info.plist

      NSLocationWhenInUseUsageDescription

如果您的目标是让地图视图显示用户的位置，那么就没有必要也没有意义告诉位置管理器做任何事情。去掉所有的代码——它实际上对你有害。只需将地图视图的userTrackingMode设置为.follow，然后退后。
