GeoFencing IOS警报范围

Question

我使用cllocationManager并在位置管理器功能中使用DidEnter和didExit来实现GeoFencing来应用此功能。控制台正在打印“ EnterRegion被呼叫”和“出口区域被呼叫”（当模拟位置在150米左右的位置），但是没有警报（通过HandleEvent调用），直到模拟位置在300米之外。

 func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
    if region is CLCircularRegion {
      handleEvent(for: region)
     // handleEventRepeat(for: region)
      print("EnterRegion getting called")
    }
  }

  func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
    if region is CLCircularRegion {
      handleEvent(for: region)
      print("ExitRegion Getting Called")
    }
  }

 func handleEvent(for region: CLRegion!){
if UIApplication.shared.applicationState == .active {
  guard let message = note(from: region.identifier) else { return }
  window?.rootViewController?.showAlert(withTitle: nil, message: message)
} else {
  guard let body = note(from: region.identifier) else { return }
  let notificationContent = UNMutableNotificationContent()
  notificationContent.title = "Alarm"
  notificationContent.body = body
  notificationContent.sound = UNNotificationSound.default()
  notificationContent.badge = UIApplication.shared.applicationIconBadgeNumber + 1 as NSNumber
  let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
  let request = UNNotificationRequest(identifier: "alarm",
                                      content: notificationContent,
                                      trigger: trigger)
  UNUserNotificationCenter.current().add(request) { error in
    if let error = error {
      print("Error: \(error)")
    }
  }

}   }
