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)
        
    }
}

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。

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

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

// 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。
