無法快速使用CLCircular Region設置要監視的區域

Question

我嘗試使用代碼在didUpdateLocations方法中設置CLCircularRegion

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    NSLog("Location Updated from did Update Locations")
    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)
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
    locationManager.delegate = self
    locationManager.startMonitoringForRegion(region)
}

錯誤發生在線上

locationManager.startMonitoringForRegion(region) 

並且發生的錯誤是

********* iPad *******[4018] <Warning>: Failed for region Error Domain=kCLErrorDomain Code=5 "(null)"

坐標和半徑已正確設置到該區域。 我也不在監視20多個區域。 我只監視一個區域。 誰能告訴我我要去哪里錯了？ 先感謝您 。

它的工作。 您可能設置了錯誤的半徑。

此代碼段對我有用：

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
    NSLog("Location Updated from did Update Locations")
    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(1000), identifier: regionID)

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