xcode - 在 Swift Xcode 7.3 中查找当前位置

Question

我目前正在开发一个项目，需要我在应用程序中获取用户位置。最初我将其编码为仅显示工作 map View ，但后来想让它显示用户位置。我不断收到错误 EXC_BAD_INSTRUCTION 线上

self.mapView.showsUserLocation = true

import UIKit
import MapKit
import CoreLocation

class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate
{
    @IBOutlet weak var mapView: MKMapView!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.locationManager.delegate = self

        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest

        self.locationManager.requestWhenInUseAuthorization()

        self.locationManager.startUpdatingLocation()

        self.mapView.showsUserLocation = true
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    // MARK: - Location Delegate Methods

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        let location = locations.last
        let center = CLLocationCoordinate2DMake(location!.coordinate.latitude, location!.coordinate.latitude)

        let region = MKCoordinateRegion(center: center, span:MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1))

        self.mapView.setRegion(region, animated: true)

        self.locationManager.startUpdatingLocation()
    }

这可能对你有帮助。

import UIKit
import CoreLocation
import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate,NSURLConnectionDelegate,UITableViewDataSource,UITableViewDelegate{

let locationManager = CLLocationManager()

var latitude = 0.00;
var Longitude = 0.00;




override func viewDidLoad() {
    super.viewDidLoad()
    locationManager.delegate = self
    locationManager.requestLocation()
    locationManager.requestWhenInUseAuthorization()
    locationManager.requestAlwaysAuthorization()
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()

    // Do any additional setup after loading the view, typically from a nib.
}


@IBOutlet weak var myLabel: UILabel!



override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}




func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location11 = locations.first {
        print("Found User's location: \(location11)")
        print("Latitude: \(location11.coordinate.latitude) Longitude: \(location11.coordinate.longitude)")
        latitude = location11.coordinate.latitude
        Longitude = location11.coordinate.longitude
        startConnection()
    }
}


func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print("Failed to find user's location: \(error.localizedDescription)")
}
