Question

我正在将iOS设备转换为iBeacon，然后使用核心位置＆＃39;范围API检测信标＆＃39;接近。现在，这有效，但我看到一个不可预测的行为，有时在一个确定的距离（比如10米之外）我看到没有灯塔有时远灯塔，有时候近灯塔。

有没有办法让这种行为更加一致？

- (void)viewDidLoad {
    [super viewDidLoad];

    self.beaconSwitch.on = NO;
    self.beaconView.backgroundColor = [UIColor clearColor];
    self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
    BeaconRegion *beaconRegion = [[BeaconRegion alloc] init];
    self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:beaconRegion.uuid major:[beaconRegion.major shortValue] minor:[beaconRegion.minor shortValue] identifier:beaconIdentifier];
}


- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self.peripheralManager stopAdvertising];
}


- (IBAction)doneButtonPressed:(id)sender {
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (IBAction)beaconSwitchPressed:(id)sender {
    if (self.beaconSwitch.on == true) {
        self.beaconView.beaconState = BNBeaconStateBroadcasting;

        NSDictionary *data = [self.beaconRegion peripheralDataWithMeasuredPower:nil];
        [self.peripheralManager startAdvertising:data];
    } else {
        self.beaconView.beaconState = BNBeaconStateStop;
        [self.peripheralManager stopAdvertising];
    }
}

以下是我将iOS设备转换为信标的方法：

以下是我如何接近它：

- (void)viewDidLoad {
    [super viewDidLoad];

    BeaconRegion *beaconRegion = [[BeaconRegion alloc] init];
    self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:beaconRegion.uuid identifier:beaconIdentifier];
    self.beaconRegion.notifyOnEntry = YES;
    self.beaconRegion.notifyOnExit = YES;
    self.beaconRegion.notifyEntryStateOnDisplay = YES;
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    self.detectionSwitch.on = NO;
}

- (IBAction)beaconDetectionSwitchPressed:(id)sender {
    if (self.detectionSwitch.isOn) {
        [self.locationManager startMonitoringForRegion:self.beaconRegion];
        [self.locationManager requestStateForRegion:self.beaconRegion];
    } else {
        self.lastProximity = CLProximityUnknown;
        [self.locationManager stopMonitoringForRegion:self.beaconRegion];
        [self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];
        self.titleLabel.text = @"";
        self.messageLabel.text = @"";
    }
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self.locationManager stopMonitoringForRegion:self.beaconRegion];
    [self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];
    self.locationManager = nil;
}

- (void)locationManager:(CLLocationManager *)iManager didEnterRegion:(CLRegion *)iRegion {
    NSLog(@"Detected a beacon");

    if (![self.beaconRegion isEqual:iRegion]) {
        return;
    }

    NSLog(@"Entered into the beacon region = %@", iRegion);

    [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}

- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
    NSLog(@"Ranging beacon successful");

    if (beacons.count > 0) {
        CLBeacon *nearestBeacon = beacons[0];
        CLProximity currentProximity = nearestBeacon.proximity;

        if (currentProximity == self.lastProximity) {
            NSLog(@"No Change in Beacon distance");
        } else {
            self.lastProximity = currentProximity;
            [self updateUserAboutProximity];
        }
    } else {
        self.lastProximity = CLProximityUnknown;

}

        case CLProximityUnknown:{
            title = @"No Beacon";
            message = @"There is no nearby beacon";
        }
            break;

        case CLProximityImmediate:{
            title = @"Immediate Beacon";
            message = @"You are standing immediate to video wall!";
        }

                }
            }

            break;

            message = @"You are standing far from video wall!";
        }
            break;
        default:

    self.titleLabel.text = title;

目前，我已经对接收信号强度指标（rssi）值设置条件并接受任何＆gt; -60近距离使距离变得更加可预测。因此，如果rssi＆gt;在附近的附近，我也会触发我的行动。 -60
