How To Limit The Amount Of Notifications - objective-c

Question

I have 3 separate ibeacons placed in 3 different rooms. When entering the region of the beacon the didRangeBeacon method runs every second, Thus resulting in an infinite number of notifications when in range.
This is the code i have:
BOOL _isInsideRegion;
- (void)locationManager:(CLLocationManager*)manager didRangeBeacons:(NSArray*)beacons inRegion:(CLBeaconRegion*)region {
CLBeacon *firstBeacon = [beacons firstObject];
int major = [firstBeacon.major intValue];
int minor = [firstBeacon.minor intValue];
if (major == 43005 && minor == 52679) {
if (!_isInsideRegion) {
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.soundName = #"Default";
notification.alertBody = #"Green";
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
self.beaconColour.text = #"Green";
self.minor.text = [NSString stringWithFormat:#"%D", minor];
self.major.text = [NSString stringWithFormat:#"%D", major];
}
}
else if (major == 48891 && minor == 47852) {
if (!_isInsideRegion) {
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.soundName = #"Default";
notification.alertBody = #"blue";
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
self.beaconColour.text = #"Blue";
self.minor.text = [NSString stringWithFormat:#"%D", minor];
self.major.text = [NSString stringWithFormat:#"%D", major];
}
}
else if (major == 59510 && minor == 42953) {
if (!_isInsideRegion) {
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.soundName = #"Default";
notification.alertBody = #"dark blue";
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
self.beaconColour.text = #"Dark Blue";
self.minor.text = [NSString stringWithFormat:#"%D", minor];
self.major.text = [NSString stringWithFormat:#"%D", major];
}
}
}
Can anybody help me so that it gives one notification upon entry, and that when i then walk to the next beacon i get another notification specific to that beacon.
Thanks.

Use the locationManager:didEnterRegion: method.
This method is called when the user enters a beacon region defined by your app.
- (void)locationManager:(CLLocationManager *)manager
didEnterRegion:(CLBeaconRegion *)region {
NSLog(#"Did Enter Region for %#", region.identifier);
//Show Notification
}
