iBeacon 基本操作

1. 設定監控信標

func initiateRegion(ref:BeaconHandler){
    let uuid: NSUUID = NSUUID(UUIDString: "<UUID>")
    let beacon = CLBeaconRegion(proximityUUID: uuid, identifier: "")
    locationManager?.requestAlwaysAuthorization()    //cllocation manager obj.
    beacon?.notifyOnEntry = true
    beacon?.notifyOnExit = true
    beacon?.notifyEntryStateOnDisplay = true
    locationManager?.startMonitoringForRegion(beacon!)
    locationManager?.delegate = self;
    // Check if beacon monitoring is available for this device
    if (!CLLocationManager.isMonitoringAvailableForClass(CLBeaconRegion)) {
        print("error")
    }
    locationManager!.startRangingBeaconsInRegion(self.beacon!)
}

2. 位置經理進入和退出區域

func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {
    if(region.isKindOfClass(CLBeaconRegion)) {
        locationManager!.startRangingBeaconsInRegion(self.beacon!)
    }
}
    
func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) {
    if(region.isKindOfClass(CLBeaconRegion)) {
        locationManager!.stopRangingBeaconsInRegion(self.beacon!)
    }
}

3. 位置經理範圍信標

func locationManager(manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
    print(beacons.first.major)
}
