这是我实现谷歌地图和CLLocationManager的代码：
class MapViewController: UIViewController {
@IBOutlet weak var MapView: GMSMapView!
var locationmanager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
locationmanager.delegate = self
locationmanager.requestWhenInUseAuthorization()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
extension MapViewController: CLLocationManagerDelegate {
private func locationManager(manager: CLLocationManager,didChangeAuthorizationStatus status: CLAuthorizationStatus) {
print("didChangeAuthorizationStatus")
if status == .authorizedWhenInUse {
locationmanager.startUpdatingLocation()
MapView.isMyLocationEnabled = true
MapView.settings.myLocationButton = true
}
}
func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
print("didUpdateLocations")
if let location = locations.first {
MapView.camera = GMSCameraPosition(target: location.coordinate,zoom: 15,bearing: 0,viewingAngle: 0)
locationmanager.stopUpdatingLocation()
}
}
}
单击允许或不允许didChangeAuthorizationStatus从未调用
解决方法
如果您使用的是Swift 3,则此方法的整个签名不正确.
这就是你需要的：
func locationManager(_ manager: CLLocationManager,didChangeAuthorization status: CLAuthorizationStatus) {
//your code
}
