Question

我已经构建了一个应用，可以在用户退出区域CLCircularRegion时发送该位置。我正在使用requestWhenInUseauthorization方法，但是询问用户是否可以使用该位置的提示不会弹出，但该位置会更新。我的位置管理器在继承到NSObject的自定义类中声明..我在视图控制器类中调用它。

这是我的代码：

class LocationProcessHandler: NSObject, CLLocationManagerDelegate {
static let sharedInstance = LocationProcessHandler()
var locationManager = CLLocationManager()

    func startLocationUpdates() {
locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters


            if #available(iOS 8.0, *) {
               // if self.locationManager.respondsToSelector(#selector(locationManager.requestWhenInUseAuthorization)) {
                self.locationManager.requestWhenInUseAuthorization()
                NSLog("The request when in use authorisation is selected")
                    self.locationManager.requestAlwaysAuthorization()
                }
                else {
                    self.locationManager.startUpdatingLocation()
                }


        NSLog("Started to monitor the significant location Changes")
    self.locationManager.stopMonitoringSignificantLocationChanges()
  self.locationManager.startMonitoringSignificantLocationChanges()
   // NSLog("the distance filter of the location manager is \(locationManager.distanceFilter)")
    }


func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {


    NSLog("Location Updated")
    let persist = Persistence()

    let currentLocation : CLLocation = locations[0]
    let latitude : Double = currentLocation.coordinate.latitude
    let Longitude : Double = currentLocation.coordinate.longitude
    let regionID = "GeoFenceTrack"
    let region : CLCircularRegion = CLCircularRegion.init(center: CLLocationCoordinate2DMake(latitude, Longitude), radius: Double(persist.getObject(mdmiosagent_Constants.LOCATIONRADIUS))!, identifier: regionID)

    NSLog("the center of the region is \(region.center) and the redius of the region is \(region.radius)")
    self.sendLocation(currentLocation)
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.delegate = self

    self.locationManager.startMonitoringForRegion(region)

}

调用didUpdate方法，但是当应用程序启动或禁用位置服务时，我无法看到任何提示。但是这会在日志中打印

 NSLog("The request when in use authorisation is selected")

我无法找出确切原因。

请帮助。提前致谢。

在您调用requestWhenInUseAuthorization的部分中，您可以使用以下内容：

$Identity

然后你需要实现 CLLocationManagerDelegate 的委托：

func startLocationUpdates(){
    ....
    //In my case my target is 8+, for this I don't check to prior version
    if CLLocationManager.authorizationStatus() == .NotDetermined{
        locationManager.requestWhenInUseAuthorization()
    }else{
        locationManager(locationManager, didChangeAuthorizationStatus: CLLocationManager.authorizationStatus())
    }
    ....
}

您是否也添加了 Info.plist NSLocationWhenInUseUsageDescription？

请求在使用时授权不起作用，尽管将内容添加到plist
