更新到iOS 12.2与Swift 5

您必须在plist文件中添加以下隐私权限

<key>NSLocationWhenInUseUsageDescription</key>
<string>Description</string>

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Description</string>

<key>NSLocationAlwaysUsageDescription</key>
<string>Description</string>

我是这样的

在Swift 2.0中获取当前位置并在地图上显示

确保你已经在你的项目中添加了CoreLocation和MapKit框架(这在XCode 7.2.1中不需要)

import Foundation
import CoreLocation
import MapKit

class DiscoverViewController : UIViewController, CLLocationManagerDelegate {
    
    @IBOutlet weak var map: MKMapView!
    var locationManager: CLLocationManager!
    
    override func viewDidLoad()
    {
        super.viewDidLoad()
       
        if (CLLocationManager.locationServicesEnabled())
        {
            locationManager = CLLocationManager()
            locationManager.delegate = self
            locationManager.desiredAccuracy = kCLLocationAccuracyBest
            locationManager.requestAlwaysAuthorization()
            locationManager.startUpdatingLocation()
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) 
    {
    
        let location = locations.last! as CLLocation
        
        let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
        
        self.map.setRegion(region, animated: true)
    }
}

这里是结果屏幕

100%工作在iOS Swift 4: Parmar Sajjad

步骤1:进入GoogleDeveloper Api控制台并创建你的ApiKey

步骤2:Goto项目安装Cocoapods GoogleMaps pod

步骤3:Goto AppDelegate.swift导入GoogleMaps和

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    GMSServices.provideAPIKey("ApiKey")
    return true
}

步骤4: 进口UIKit 进口GoogleMaps 类ViewController: UIViewController, CLLocationManagerDelegate {

@IBOutlet weak var mapview: UIView!
let locationManager  = CLLocationManager()

override func viewDidLoad() {
    super.viewDidLoad()
    locationManagerSetting()
    // 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.
}


func locationManagerSetting() {

    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    self.showCurrentLocationonMap()
    self.locationManager.stopUpdatingLocation()
}
func showCurrentLocationonMap() {
    let
    cameraposition  = GMSCameraPosition.camera(withLatitude: (self.locationManager.location?.coordinate.latitude)!  , longitude: (self.locationManager.location?.coordinate.longitude)!, zoom: 18)
    let  mapviewposition = GMSMapView.map(withFrame: CGRect(x: 0, y: 0, width: self.mapview.frame.size.width, height: self.mapview.frame.size.height), camera: cameraposition)
    mapviewposition.settings.myLocationButton = true
    mapviewposition.isMyLocationEnabled = true

    let marker = GMSMarker()
    marker.position = cameraposition.target
    marker.snippet = "Macczeb Technologies"
    marker.appearAnimation = GMSMarkerAnimation.pop
    marker.map = mapviewposition
    self.mapview.addSubview(mapviewposition)

}

}

第五步:打开信息。plist文件和添加下面的隐私-使用时的位置使用说明......在主故事板文件基名下面

第六步:运行

// 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)

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。

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)") }

下面是一个适用于我的复制粘贴示例。

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)")
    }
}
