我试图将ObjC中的旧应用程序转换为Swift作为练习练习并且遇到了一些问题.我在旧应用程序中使用它的方式,它是建立CLLocation Manager然后我会使用:

manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;    
[manager startUpdatingLocation]

会自动调用:

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
}

从那里我可以提取我需要的所有信息.但是在swift中,没有自动完成这种方法,我无法弄清楚如何重现它.文档说明了这一点

startUpdatingLocation()

仍将由代表调用,但它没有发生.

这是我到目前为止:

import UIKit
import corelocation

class ViewController: UIViewController,CLLocationManagerDelegate{

@IBOutlet var gpsResult : UILabel

var manager:CLLocationManager!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

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

func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
    println("locations = \(locations)")
    gpsResult.text = "success" …

我正在为iOS 8开发一段Swift代码.我正在尝试做一些涉及位置的事情,所以我在我的swift视图控制器文件中实现了以下内容:

let locationManger:CLLocationManager = CLLocationManager()

var speedReceived:Double = 0

override func viewDidLoad() {
    super.viewDidLoad()
    locationManger.delegate = self
    locationManger.desiredAccuracy = kCLLocationAccuracyBest
    let authstate = CLLocationManager.authorizationStatus()
    if(authstate == CLAuthorizationStatus.NotDetermined){
       println("Not Authorised")  
      locationManger.requestWhenInUseAuthorization()
    }
    // Do any additional setup after loading the view, typically from a nib.
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!){
    var location:CLLocation = locations[locations.count - 1] as CLLocation
    if(location.horizontalAccuracy > 0){
        self.speedReceived = location.speed
        println(self.speedReceived)
    }
}

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
   println("Couldn't get your location") …
