私はヘルパークラスを作り、パターンHelperLocationManagerを追加しましたnotification- observer
import UIKit
import CoreLocation
class HelperLocationManager: NSObject {
var locationManager = CLLocationManager()
static let sharedInstance = HelperLocationManager()
var currentLocation :CLLocation?
var notGotUserLocation = true
override init() {
super.init()
var code = CLLocationManager.authorizationStatus()
if code == CLAuthorizationStatus.NotDetermined {
locationManager.requestAlwaysAuthorization()
locationManager.requestWhenInUseAuthorization()
}
locationManager.requestAlwaysAuthorization()
locationManager.requestWhenInUseAuthorization()
locationManager.delegate = self
locationManager.distanceFilter = 100;
}
}
extension HelperLocationManager: CLLocationManagerDelegate{
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
var locValue = locations.last as! CLLocation
println(locValue)
self.currentLocation = locValue
NSNotificationCenter.defaultCenter().postNotificationName("sendCurrentAddressToViewController", object:self.currentLocation)
notGotUserLocation = false
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
println("Your error is ", error.localizedDescription)
}
}
クラスに場所が必要な場合Viewcontrollerは、そこにオブザーバーを配置します
var helperLocation:HelperLocationManager?
のviewDidLoadように
override func viewDidLoad() {
helperLocation = HelperLocationManager()
NSNotificationCenter.defaultCenter().addObserver(self, selector: "getCurrentAddressToViewController:", name: "sendCurrentAddressToViewController", object: nil)
}
//そしてオブザーバーとして
func getCurrentAddressToViewController(notification: NSNotification) {
currentLocation = notification.object as? CLLocation
NSNotificationCenter.defaultCenter().removeObserver(self, name: "sendCurrentAddressToViewController", object: nil)
}
//didUpdateLocation複数回呼び出さobserverれますが、場所を取得した後に削除するため、場所を取得するのは 1 回だけです。
編集：notificationobserverパターンを追加する必要がないように、このヘルパークラスを屈折させました
class HelperLocationManager: NSObject {
private lazy var locationManager = CLLocationManager()
static let sharedInstance = HelperLocationManager()
var currentLocation :CLLocation?
override init() {
super.init()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.delegate = self
}
}
extension HelperLocationManager: CLLocationManagerDelegate{
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case CLAuthorizationStatus.NotDetermined:
locationManager.requestWhenInUseAuthorization()
case CLAuthorizationStatus.Restricted:
PrinterHelper.messagePrinter("Restricted Access to location")
case CLAuthorizationStatus.Denied:
PrinterHelper.messagePrinter("User denied access to location")
case CLAuthorizationStatus.AuthorizedWhenInUse:
if #available(iOS 9.0, *) {
locationManager.requestLocation()
} else {
locationManager.startUpdatingLocation()
}
default:
PrinterHelper.messagePrinter("default authorization")
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let locValue = locations.last
HelperLocationManager.sharedInstance.currentLocation = locValue
locationManager.stopUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
PrinterHelper.errorPrinter(error.localizedDescription)
}
}
ユーザー権限を取得する必要があるView Controller
var helperLocationManager:HelperLocationManager?
のviewDidLoadように
override func viewDidLoad() {
helperLocationManager = HelperLocationManager.sharedInstance
}
currentLocationそして、シングルトンプロパティを次のように呼び出す必要がある場所を取得するには
if let userCurentLoc = HelperLocationManager.sharedInstance.currentLocation{
//userCurrentLoc is the user Location
}
