beaconManager.startRangingBeacons(in: region)
}
func beaconManager(_ manager: Any, didEnter region: CLBeaconRegion) {
NSLog("beaconManager : didEnter Called")
let content = UNMutableNotificationContent()
content.title = "Beacon Detected"
content.body = "Enter region"
content.sound = UNNotificationSound.default()
let trigger = UNLocationNotificationTrigger(region:region, repeats:false)

center.add(request) { (error) in
if let error = error {
print(error.localizedDescription)
}
}
}
func beaconManager(_ manager: Any, didExitRegion region: CLBeaconRegion) {
NSLog("beaconManager : didExitRegion Called")
let content = UNMutableNotificationContent()
content.title = "Beacon Detected"
content.body = "Exit region"
content.sound = UNNotificationSound.default()
let trigger = UNLocationNotificationTrigger(region:region, repeats:false)
let request = UNNotificationRequest(identifier: "Enter region", content: content, trigger: trigger)
center.add(request) { (error) in
if let error = error {

In app delegate write the desired code under estimate delegate methods. Sample code as follows,
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
if launchOptions["UIApplicationLaunchOptionsLocationKey"] != nil {
beaconManager = ESTBeaconManager()
beaconManager.delegate = self
// don't forget the NSLocationAlwaysUsageDescription in your Info.plist
beaconManager.requestAlwaysAuthorization()
beaconManager.startMonitoring(for: ESTBeaconRegion(proximityUUID: ESTIMOTE_PROXIMITY_UUID, identifier: "AppRegion"))
}
return true
}
func beaconManager(_ manager: ESTBeaconManager, didEnter region: ESTBeaconRegion) {
let notification = UILocalNotification()
notification.alertBody = "Enter region"
notification.soundName = UILocalNotificationDefaultSoundName as? String
UIApplication.shared.presentLocalNotificationNow(notification)
}
func beaconManager(_ manager: ESTBeaconManager, didExitRegion region: ESTBeaconRegion) {
let notification = UILocalNotification()
notification.alertBody = "Exit region"
notification.soundName = UILocalNotificationDefaultSoundName as? String
UIApplication.shared.presentLocalNotificationNow(notification)
}
This is old code, may have few changes. Follow estimate community's thread for more information. You can find your problem on this thread https://community.estimote.com/hc/en-us/articles/203253193-Pushing-notifications-from-iBeacon-when-the-app-is-in-the-background-or-killed
