如何在swift中获取CLLocationManager的位置用户？ [英] How to get Location user whith CLLocationManager in swift?

问题描述

我在我的视图控制器上有这个代码，但这不起作用：

I have this code on my view controller but this not working:

 import UIKit
 import CoreLocation
 class ViewController: UIViewController, CLLocationManagerDelegate {

  var location: CLLocationManager!

 override func viewDidLoad() {
    super.viewDidLoad()

    location=CLLocationManager()
    location.delegate = self
    location.desiredAccuracy=kCLLocationAccuracyBest
    location.startUpdatingLocation()
}

 func locationManager(location:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
    println("locations = \(locations)")
    label1.text = "success"
}

我对其他帖子中的阅读方式有所了解。但是我没有得到永远，没有印刷品..

I have the permisions how I read in other post. but I don't obtain never, no println..

谢谢!!

推荐答案

首先在plist文件中添加这两行

first add this two line in plist file

1） NSLocationWhenInUseUsageDescription

2） NSLocationAlwaysUsageDescription

然后这是类工作完成实现这个

Then this is class working complete implement this

import UIKit 
import CoreLocation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {

var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    initLocationManager();
    return true
}

// Location Manager helper stuff
func initLocationManager() {
    seenError = false
    locationFixAchieved = false
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.locationServicesEnabled
    locationManager.desiredAccuracy = kCLLocationAccuracyBest

    locationManager.requestAlwaysAuthorization()
}

// Location Manager Delegate stuff

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    locationManager.stopUpdatingLocation()
    if (error) {
        if (seenError == false) {
            seenError = true
           print(error)
        }
    }
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {
    if (locationFixAchieved == false) {
        locationFixAchieved = true
        var locationArray = locations as NSArray
        var locationObj = locationArray.lastObject as CLLocation
        var coord = locationObj.coordinate

        println(coord.latitude)
        println(coord.longitude)
    }
}

func locationManager(manager: CLLocationManager!,
    didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        var shouldIAllow = false

        switch status {
        case CLAuthorizationStatus.Restricted:
            locationStatus = "Restricted Access to location"
        case CLAuthorizationStatus.Denied:
            locationStatus = "User denied access to location"
        case CLAuthorizationStatus.NotDetermined:
            locationStatus = "Status not determined"
        default:
            locationStatus = "Allowed to location Access"
            shouldIAllow = true
        }
        NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
        if (shouldIAllow == true) {
            NSLog("Location to Allowed")
            // Start location services
            locationManager.startUpdatingLocation()
        } else {
            NSLog("Denied access: \(locationStatus)")
        }
}
}
