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

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)") }

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。

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。

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
