CLLocationManagerDelegate方法不适用于Apple Watch扩展

我正在研究Apple Watch应用程序以检索用户位置。我已经将CoreLocation框架导入interfacecontroller类，并向该类添加了委托。这是行不通的。请检查下面的代码。我想念什么？

    import Foundation
    import WatchKit
    import CoreLocation


    class NearByController: WKInterfaceController, CLLocationManagerDelegate {



override func awakeWithContext(context: AnyObject?) {

    var locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestWhenInUseAuthorization()
    if CLLocationManager.locationServicesEnabled() {
        locationManager.startUpdatingLocation()

    }
}

// MARK: CLLocationManagerDelegate

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    println("Retrieved location")
}



func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    println(error)
}

似乎我需要将CLLocationManager初始化为类属性，而不是内部方法。这是我的答案。现在正在工作。

import Foundation
import WatchKit
import CoreLocation


class NearByController: WKInterfaceController, CLLocationManagerDelegate {


var locationManager = CLLocationManager()

override func awakeWithContext(context: AnyObject?) {

    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestWhenInUseAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.startUpdatingLocation()
    }
}


// MARK: CLLocationManagerDelegate


func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    locationManager.stopUpdatingLocation()
    println(locations)
}



func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    println(error)
}
