How to stop iBeacon scanning - ios

Question

i tried with this Code but this delegates are not calling and not stoping the scanning, at one particular condition i need to call some other function.
-(void)locationManager:(CLLocationManager *)manager stopRangingBeaconsInRegion:(CLBeaconRegion *)region
{
NSLog(#"STOP PLEASEEEEEEEE");
}
- (void)locationManager:(CLLocationManager *)manager stopMonitoringForRegion:(CLRegion *)region {
NSLog(#"didExitRegion");
[manager stopRangingBeaconsInRegion:(CLBeaconRegion*)region];
NSLog(#"StopRangingBeacons");
}
am using this code to start the beaconScanning
-(void)loadUIElements
{
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND , 0), ^{
self.beaconRegionAny = [[AIBBeaconRegionAny alloc] initWithIdentifier:#"Any"];
[self.locationManager requestWhenInUseAuthorization];
self.locationManager.pausesLocationUpdatesAutomatically = YES;
[self.locationManager startRangingBeaconsInRegion:self.beaconRegionAny]; });
}
calling this function when start monitoring the beacons
- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{

Answer 1

You have to remove the listener from your monitoredRegions list using stopMonitoring(for:). Here'a a link to the documentation
Have you tried this?
[self.locationManager stopMonitoringForRegion:self.beaconRegionAny];

Answer 2

create a button action and this line of code.
#IBAction func launchButtonClicked(_ sender: Any) {
// Determine action based on button state
switch (launchButton.currentState) {
case .Start:
beaconManager.startRangingBeacons(in: region)
launchButton.currentState = .Stop
case .Stop:
beaconManager.stopRangingBeacons(in: region)
launchButton.currentState = .Start
}
}
Try this way, it works
