我想在我的应用上使用后台获取位置更新服务.但是不要在这里显示任何输出我的代码我想要你的帮助.
import CoreLocation
class ViewController: UIViewController, UITextFieldDelegate, CLLocationManagerDelegate {
var locationManager:CLLocationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
print("didChangeAuthorizationStatus")
switch status {
case .NotDetermined:
print(".NotDetermined")
break
case .Authorized:
print(".Authorized")
self.locationManager.startUpdatingLocation()
break
case .Denied:
print(".Denied")
break
default:
print("Unhandled authorization status")
break
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last as CLLocation!
print("didUpdateLocations: \(location.coordinate.latitude), \(location.coordinate.longitude)")
}
仅提供输出
didChangeAuthorizationStatus
.NotDetermined
如果有可能我想在新位置改变时采用长拉特值.
谢谢 !
最佳答案 我把它添加到info.plist文件中:
<key>NSLocationAlwaysUsageDescription</key>
<string>Your message goes here</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Your message goes here</string>
