import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    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.
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        determineMyCurrentLocation()
    }


    func determineMyCurrentLocation() {
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()

        if CLLocationManager.locationServicesEnabled() {
            locationManager.startUpdatingLocation()
            //locationManager.startUpdatingHeading()
        }
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let userLocation:CLLocation = locations[0] as CLLocation

        // Call stopUpdatingLocation() to stop listening for location updates,
        // other wise this function will be called every time when user location changes.

       // manager.stopUpdatingLocation()

        print("user latitude = \(userLocation.coordinate.latitude)")
        print("user longitude = \(userLocation.coordinate.longitude)")
    }

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

// its with strongboard 
@IBOutlet weak var mapView: MKMapView!

//12.9767415,77.6903967 - exact location latitude n longitude location 
let cooridinate = CLLocationCoordinate2D(latitude: 12.9767415 , longitude: 77.6903967)
let  spanDegree = MKCoordinateSpan(latitudeDelta: 0.2,longitudeDelta: 0.2)
let region = MKCoordinateRegion(center: cooridinate , span: spanDegree)
mapView.setRegion(region, animated: true)

像这样导入库:

import CoreLocation

设置委托:

CLLocationManagerDelegate

取如下变量:

var locationManager:CLLocationManager!

在viewDidLoad()上写这样漂亮的代码:

 locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()

    if CLLocationManager.locationServicesEnabled(){
        locationManager.startUpdatingLocation()
    }

编写CLLocation委托方法:

    //MARK: - location delegate methods
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let userLocation :CLLocation = locations[0] as CLLocation

    print("user latitude = \(userLocation.coordinate.latitude)")
    print("user longitude = \(userLocation.coordinate.longitude)")

    self.labelLat.text = "\(userLocation.coordinate.latitude)"
    self.labelLongi.text = "\(userLocation.coordinate.longitude)"

    let geocoder = CLGeocoder()
    geocoder.reverseGeocodeLocation(userLocation) { (placemarks, error) in
        if (error != nil){
            print("error in reverseGeocode")
        }
        let placemark = placemarks! as [CLPlacemark]
        if placemark.count>0{
            let placemark = placemarks![0]
            print(placemark.locality!)
            print(placemark.administrativeArea!)
            print(placemark.country!)

            self.labelAdd.text = "\(placemark.locality!), \(placemark.administrativeArea!), \(placemark.country!)"
        }
    }

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

现在设置访问位置的权限，将这些键值添加到您的信息中。plist文件

 <key>NSLocationAlwaysUsageDescription</key>
<string>Will you allow this app to always know your location?</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Do you allow this app to know your current location?</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Do you allow this app to know your current location?</string>

100%工作，没有任何问题。测试

下面是一个适用于我的复制粘贴示例。

http://swiftdeveloperblog.com/code-examples/determine-users-current-location-example-in-swift/

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    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.
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        determineMyCurrentLocation()
    }


    func determineMyCurrentLocation() {
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()

        if CLLocationManager.locationServicesEnabled() {
            locationManager.startUpdatingLocation()
            //locationManager.startUpdatingHeading()
        }
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let userLocation:CLLocation = locations[0] as CLLocation

        // Call stopUpdatingLocation() to stop listening for location updates,
        // other wise this function will be called every time when user location changes.

       // manager.stopUpdatingLocation()

        print("user latitude = \(userLocation.coordinate.latitude)")
        print("user longitude = \(userLocation.coordinate.longitude)")
    }

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

要获取用户的当前位置，你需要声明:

let locationManager = CLLocationManager()

在viewDidLoad()中，你必须实例化CLLocationManager类，就像这样:

// Ask for Authorisation from the User.
self.locationManager.requestAlwaysAuthorization() 

// For use in foreground
self.locationManager.requestWhenInUseAuthorization()

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

然后在CLLocationManagerDelegate方法中，你可以获得用户当前的位置坐标:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
    print("locations = \(locValue.latitude) \(locValue.longitude)")
}

在信息中。plist你必须添加NSLocationAlwaysUsageDescription 和你的自定义警报消息像;AppName(演示应用程序)想使用您的当前位置。

NSLocationWhenInUseUsageDescription =请求权限使用位置服务时，应用程序是在后台。在你的plist文件中。

如果这是工作，然后请投票的答案。
