使用Swift查找纬度和经度

Question

I like to know if it is possible to find the Latitude and the Longitude on iPhone that is not connected to WIFI and using cellular data while inside a building with Swift?

IF not what is the alternative way of determine that?

Answer 1

Try this code in order to get the Latitude and the Longitude:

First create an instance of CLLocationManager and Request Authorization

var locManager = CLLocationManager()
locManager.requestWhenInUseAuthorization()

then check if the user allowed authorization.

var currentLocation = CLLocation!

if( CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedWhenInUse ||
        CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized){

      currentLocation = locManager.location

}

to use it just do this

label1.text = "\(currentLocation.coordinate.longitude)"
label2.text = "\(currentLocation.coordinate.latitude)"

Answer 2

For iOS 8 and swift2.3 add your project's info.plist privacy for always location use and then use this code

let locationManager = CLLocationManager()
var userLatitude:CLLocationDegrees! = 0
var userLongitude:CLLocationDegrees! = 0

use this code in viewDidLoad -

self.locationManager.requestAlwaysAuthorization()
self.locationManager.requestWhenInUseAuthorization()

if CLLocationManager.locationServicesEnabled()

{
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    locationManager.startMonitoringSignificantLocationChanges()

    userLatitude  = locationManager.location?.coordinate.latitude
    userLongitude  = locationManager.location?.coordinate.longitude
}
