使用 xcode 从 osx/cocoa 应用获取当前位置 swift 3

Question

对于没有提供代码，我深表歉意。我用图片发布它的原因是因为 xcode 是 LLVM（低级虚拟机） 编译器，它主要有 UI 环境 特别是 配置部分 。例如通过将它们拖到视图控制器而不是直接通过代码定义它来为对象创建出口或动作。既然如此，我想人们会很快注意到我的错误。

import Cocoa
import MapKit

class ViewController: NSViewController, CLLocationManagerDelegate {

   @IBOutlet var mapView: MKMapView!
   var locManager = CLLocationManager()
   var currentLocation = CLLocation()

   var locationManager = CLLocationManager()
   var didFindMyLocation = false
   var strForCurLatitude = "";
   var strForCurLongitude = "";

   override func viewDidLoad() {
       super.viewDidLoad()

       let distancespan:CLLocationDegrees = 2000
       let busCScampuslocation:CLLocationCoordinate2D =  CLLocationCoordinate2DMake(currentLocation.coordinate.latitude, currentLocation.coordinate.longitude)
       mapView.setRegion(MKCoordinateRegion.init(center: bsuCScampuslocation, latitudinalMeters: distancespan, longitudinalMeters: distancespan), animated: true)
       print(currentLocation.coordinate.latitude)
   }
   ...
}

Swift 5:

ViewController.swift

import Cocoa
import CoreLocation
import MapKit

class ViewController: NSViewController, CLLocationManagerDelegate {

       let manager = CLLocationManager()

       override func viewDidLoad() {
           super.viewDidLoad()
           manager.delegate = self
           manager.startUpdatingLocation()
       }

       func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
            print(locations)
            //This is where you can update the MapView when the computer is moved (locations.last!.coordinate)
       }

       func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
            print(error)
       }

       func locationManager(_ manager: CLLocationManager,
                     didChangeAuthorization status: CLAuthorizationStatus) {
           print("location manager auth status changed to: " )
           switch status {
               case .restricted:
                    print("restricted")
               case .denied:
                    print("denied")
               case .authorized:
                    print("authorized")
               case .notDetermined:
                    print("not yet determined")
               default:
                    print("Unknown")
       }

}

将这些行添加到 Info.plist 或将 NSLocationAlwaysAndWhenInUseUsageDescription 和/（或？）NSLocationUsageDescription 设置为明文说明为什么需要访问用户位置

    <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
        <string>Allows us to locate you</string>
    <key>NSLocationUsageDescription</key>
        <string>Allows us to locate you</string>

如果用户关闭定位服务，授权状态将为'denied'
