Finding Altitude in Swift

问题

I've been having trouble finding a way to get the altitude of the device. Could someone give me a pointer or put together a short script that gets the altitude of the device and prints it? Only in swift. Thanks!

回答1:

Import CoreLocation

import CoreLocation

Create a locationManger variable

var locationManager:CLLocationManager = CLLocationManager()

Initialize and start updating location

override func viewDidLoad() {
    super.viewDidLoad()
    self.locationManager = CLLocationManager()
    locationManager.requestWhenInUseAuthorization()
    self.locationManager.delegate = self
    self.locationManager.distanceFilter = kCLDistanceFilterNone
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.startUpdatingLocation()
}


func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!) {
   var alt = newLocation.altitude
   println("\(alt)")
   manager.stopUpdatingLocation()
}
