iOS_Back_3

to do a iBeacon Sensor feature with sys notification when app is running in background

1. define K/V in info propert list.

2. code in ViewController.

    import UIKit
    import CoreBluetooth
    import CoreLocation
   
    class ViewController: UIViewController, CLLocationManagerDelegate {
   
        let cllm = CLLocationManager()
   
        override func viewDidLoad() {
            super.viewDidLoad()
            // after nib.
   
            cllm.requestAlwaysAuthorization()
            cllm.delegate = self
   
            // search for Beacon's UUID, which is 20 bytes.
            let uuid = UUID(uuidString: "B9407F30-F5F8-466E-AFF9-25556B57FE6D")
            let region = CLBeaconRegion(uuid: uuid!, identifier: "Kates Region")
   
            // this app helps to detect info of nearby beacon device.
            // cllm.startRangingBeacons is deprecated.
            cllm.startMonitoring(for: region)
   
            // to know how many and what are they
            // matters with major, minor, accury
            //cllm.startRangingBeacons(satisfying: <#T##CLBeaconIdentityConstraint#>)
   
        }
   
        // when app running at background.
        // method below can be called.
   
        func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
            print("Enter\(region.identifier)")
        }
   
        func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
            print("Exit\(region.identifier)")
        }
   
   
    }
