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

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。

之前所有的答案都没有正确地遵循正确的步骤。当设置CLLocationManager时，您不需要最初调用CLLocationManager. locationservicesenabled()或locationManager.requestWhenInUseAuthorization()。你不应该调用startUpdatingLocation()，直到你已经验证你有授权。

要开始，如果还没有完成，请添加所需的隐私设置。选择你的应用目标，然后转到信息选项卡。在“自定义iOS目标属性”部分右键单击并选择“添加行”。向下滚动到“隐私”条目，并选择其中之一:

"隐私-使用时的位置使用说明" "隐私-位置始终使用说明" 隐私-使用时的位置使用说明

这取决于你的应用程序的需求。对于这个值，确保你输入了一个句子，向用户解释为什么你的应用程序需要访问他们的位置。如果所提供的描述对用户没有用处，你的应用可能会被苹果拒绝。

然后使用以下(大量注释)代码作为示例，在视图控制器中获取用户的位置:

import UIKit
import CoreLocation

class ViewController: UIViewController {
    var locationManager: CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Setup the location manager
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation // Or other desired accuracy

        // That's it for the initial setup. Everything else is handled in the
        // locationManagerDidChangeAuthorization delegate method.
    }
}

extension ViewController: CLLocationManagerDelegate {
    // This is called as soon as the location manager is setup (in viewDidLoad)
    // This is called when the user responds to the privacy dialog
    // This is called if the user changes the privacy setting in the Settings app
    func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
        switch manager.authorizationStatus {
        case .notDetermined:
            // Request the appropriate authorization based on the needs of the app
            manager.requestWhenInUseAuthorization()
            // manager.requestAlwaysAuthorization()
        case .restricted:
            print("Sorry, restricted")
            // Optional: Offer to take user to app's settings screen
        case .denied:
            print("Sorry, denied")
            // Optional: Offer to take user to app's settings screen
        case .authorizedAlways, .authorizedWhenInUse:
            // The app has permission so start getting location updates
            manager.startUpdatingLocation()
        @unknown default:
            print("Unknown status")
        }
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("Received \(locations.count) locations")

        // Some location updates can be invalid or have insufficient accuracy.
        // Find the first location that has sufficient horizontal accuracy.
        // If the manager's desiredAccuracy is one of kCLLocationAccuracyNearestTenMeters,
        // kCLLocationAccuracyHundredMeters, kCLLocationAccuracyKilometer, or kCLLocationAccuracyThreeKilometers
        // then you can use $0.horizontalAccuracy <= manager.desiredAccuracy. Otherwise enter the number of meters desired.
        if let location = locations.first(where: { $0.horizontalAccuracy <= 40 }) {
            print("Good location found: \(location)")
            // Call the following if you don't need any more updates
            manager.stopUpdatingLocation()

            // Do something useful with the found location
            // - show on a map
            // - Reverse geocode to get the address
            // - send to server
        }
    }

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

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

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。
