Objective c 如何限制通知的数量

我有3个独立的iBeacon放在3个不同的房间里。当进入信标区域时，didRangeBeacon方法每秒运行一次，从而在范围内产生无限多的通知

这是我的代码：

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];

            }
        }

    }

有谁能帮助我，让它在进入时发出一个通知，然后当我走到下一个信标时，我会收到另一个特定于该信标的通知。

谢谢。

使用

locationManager:didEnterRegion:

方法

当用户输入应用程序定义的信标区域时，将调用此方法

- (void)locationManager:(CLLocationManager *)manager
     didEnterRegion:(CLBeaconRegion *)region {

    NSLog(@"Did Enter Region for %@", region.identifier);
    //Show Notification

}
