import CoreLocation
import UIKit

class ViewController: UIViewController, CLLocationManagerDelegate {

    var locationManager: CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
    } 

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status != .authorizedWhenInUse {return}
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
        let locValue: CLLocationCoordinate2D = manager.location!.coordinate
        print("locations = \(locValue.latitude) \(locValue.longitude)")
    }
}

因为requestWhenInUseAuthorization的调用是异步的，所以应用程序在用户授予权限或拒绝它之后才调用locationManager函数。因此，在给定用户权限的情况下，在函数中放置位置获取代码是合适的。这是我找到的最好的教程。

你应该做这些步骤:

add CoreLocation.framework to BuildPhases -> Link Binary With Libraries (no longer necessary as of XCode 7.2.1) import CoreLocation to your class - most likely ViewController.swift add CLLocationManagerDelegate to your class declaration add NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription to plist init location manager: locationManager = CLLocationManager() locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest locationManager.requestAlwaysAuthorization() locationManager.startUpdatingLocation() get User Location By: func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { let locValue:CLLocationCoordinate2D = manager.location!.coordinate print("locations = \(locValue.latitude) \(locValue.longitude)") }

首先在项目中添加两个框架

1:地

2:共重定位(从XCode 7.2.1开始不再需要)

在类中定义

var manager:CLLocationManager!
var myLocations: [CLLocation] = []

然后在viewDidLoad方法中编写此代码

manager = CLLocationManager()
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestAlwaysAuthorization()
manager.startUpdatingLocation()

//Setup our Map View
mapobj.showsUserLocation = true

不要忘记在plist文件中添加这两个值

1: NSLocationWhenInUseUsageDescription

2: NSLocationAlwaysUsageDescription

如果你不想在地图中显示用户位置，而只是想将其存储在firebase或其他地方，那么请遵循以下步骤，

import MapKit
import CoreLocation

现在在你的VC上使用CLLocationManagerDelegate，你必须覆盖下面显示的最后三个方法。您可以看到requestLocation()方法如何使用这些方法获取当前用户位置。

class MyVc: UIViewController, CLLocationManagerDelegate {

  let locationManager = CLLocationManager()

 override func viewDidLoad() {
    super.viewDidLoad()

    isAuthorizedtoGetUserLocation()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    }
}

 //if we have no permission to access user location, then ask user for permission.
func isAuthorizedtoGetUserLocation() {

    if CLLocationManager.authorizationStatus() != .authorizedWhenInUse     {
        locationManager.requestWhenInUseAuthorization()
    }
}


//this method will be called each time when a user change his location access preference.
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    if status == .authorizedWhenInUse {
        print("User allowed us to access location")
        //do whatever init activities here.
    }
}


 //this method is called by the framework on         locationManager.requestLocation();
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print("Did location updates is called")
    //store the user location here to firebase or somewhere 
}

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
    print("Did location updates is called but failed getting location \(error)")
}

}

现在，一旦用户登录到您的应用程序，您就可以编写下面的调用。当requestLocation()被调用时，它将进一步调用上面的didUpdateLocations，您可以将位置存储到Firebase或其他任何地方。

if CLLocationManager.locationServicesEnabled() {
            locationManager.requestLocation();
 }

如果你正在使用GeoFire，那么在上面的didUpdateLocations方法中，你可以像下面那样存储位置

geoFire?.setLocation(locations.first, forKey: uid) where uid is the user id who logged in to the app. I think you will know how to get UID based on your app sign in implementation. 

最后但并非最不重要的，去你的信息。plist并启用“Privacy -Location when in Use Usage Description.”

当您使用模拟器测试时，它总是给您一个自定义位置，您在模拟器中配置->调试->位置。

 override func viewDidLoad() {

    super.viewDidLoad()       
    locationManager.requestWhenInUseAuthorization();     
    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.startUpdatingLocation()
    }
    else{
        print("Location service disabled");
    }
  }

这是你的视图didload方法，在ViewController类中还包括mapStart更新方法，如下所示

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var locValue : CLLocationCoordinate2D = manager.location.coordinate;
    let span2 = MKCoordinateSpanMake(1, 1)    
    let long = locValue.longitude;
    let lat = locValue.latitude;
    print(long);
    print(lat);        
    let loadlocation = CLLocationCoordinate2D(
                    latitude: lat, longitude: long            

   )     

    mapView.centerCoordinate = loadlocation;
    locationManager.stopUpdatingLocation();
}

另外，不要忘记添加CoreLocation。框架和MapKit。项目中的框架(从XCode 7.2.1开始不再需要)

首先导入Corelocation和MapKit库:

import MapKit
import CoreLocation

从CLLocationManagerDelegate继承到我们的类

class ViewController: UIViewController, CLLocationManagerDelegate

创建一个locationManager变量，这将是你的位置数据

var locationManager = CLLocationManager()

创建一个函数来获取位置信息，具体语法如下:

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

在函数中为用户的当前位置创建一个常量

let userLocation:CLLocation = locations[0] as CLLocation // note that locations is same as the one in the function declaration  

停止更新位置，这可以防止你的设备在移动时不断地改变窗口以使你的位置居中(如果你想让它发挥其他作用，你可以省略这个)

manager.stopUpdatingLocation()

从刚刚定义的userLocatin获取用户坐标:

let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)

定义你想要缩放的地图:

let span = MKCoordinateSpanMake(0.2,0.2) 将这两个组合起来得到region:

let region = MKCoordinateRegion(center: coordinations, span: span)//this basically tells your map where to look and where from what distance

现在设置区域，并选择是否希望它与动画一起去那里

mapView.setRegion(region, animated: true)

关闭函数 ｝

从你的按钮或者其他你想要设置locationManagerDeleget为self的方式

现在允许显示位置

指定精度

locationManager.desiredAccuracy = kCLLocationAccuracyBest

授权:

 locationManager.requestWhenInUseAuthorization()

为了能够授权位置服务，您需要将这两行添加到您的plist

位置:

locationManager.startUpdatingLocation()

显示给用户:

mapView.showsUserLocation = true

这是我的完整代码:

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: MKMapView!
    
    var locationManager = CLLocationManager()
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

  
    @IBAction func locateMe(sender: UIBarButtonItem) {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
        
        mapView.showsUserLocation = true
        
    }
    
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let userLocation:CLLocation = locations[0] as CLLocation
        
        manager.stopUpdatingLocation()
        
        let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
        let span = MKCoordinateSpanMake(0.2,0.2)
        let region = MKCoordinateRegion(center: coordinations, span: span)
        
        mapView.setRegion(region, animated: true)
        
    }
}
