如何在不知道 iOS 中的 UUID 的情况下检测 ibeacon 设备?

How to detect ibeacon device without knowing UUID in iOS?

我想开发在不知道 uuid 的情况下检测大量信标设备的应用程序。但是我找不到办法做到这一点。我必须在代码中定义 uuid。

我开发了一个适用于已知设备的 POC。

我的视图控制器代码:

-(void)setUpview
{
     // Regardless of whether the device is a transmitter or receiver, we need a beacon region.
    NSUUID * uid = [[NSUUID alloc] initWithUUIDString:@"78CDC73D-D678-4B35-A88A-C2E09E5B963F"];//[UIDevice currentDevice].identifierForVendor;
    treasureId = @"com.eden.treasure";
    self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uid identifier:treasureId];

    // Location manager.
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;

    if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
        [self.locationManager requestAlwaysAuthorization];
    }

    [self.locationManager startMonitoringForRegion:self.beaconRegion];
    [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
    [self locationManager:self.locationManager didStartMonitoringForRegion:self.beaconRegion];

    [self.beaconRegion setNotifyEntryStateOnDisplay:YES];
    [self.beaconRegion setNotifyOnEntry:YES];
    [self.beaconRegion setNotifyOnExit:YES];

//    self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
    if ([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad || [[[UIDevice currentDevice] model] isEqualToString:@"iPad Simulator"])
    {
        [self configureTransmitter];
    }
    else {
        [self configureReceiver];
    }
}


-(void)configureTransmitter
{
    // The received signal strength indicator (RSSI) value (measured in decibels) for the device. This value represents the measured strength of the beacon from one meter away and is used during ranging. Specify nil to use the default value for the device.
    NSNumber * power = [NSNumber numberWithInt:-63];
    self.peripheralData = [self.beaconRegion peripheralDataWithMeasuredPower:power];
    // Get the global dispatch queue.
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    // Create a peripheral manager.
    self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:queue];
}

-(void)configureReceiver {
    // Location manager.
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    [self.locationManager requestAlwaysAuthorization];
    [self.locationManager startMonitoringForRegion:self.beaconRegion];
    [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}
#pragma mark - CBPeripheralManagerDelegate methods

-(void)peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral
{
    // The peripheral is now active, this means the bluetooth adapter is all good so we can start advertising.
    if (peripheral.state == CBPeripheralManagerStatePoweredOn)
    {
        [self.peripheralManager startAdvertising:self.peripheralData];
    }
    else if (peripheral.state == CBPeripheralManagerStatePoweredOff)
    {
        NSLog(@"Powered Off");
        [self.peripheralManager stopAdvertising];
    }  
}
-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
{
    if(state == CLRegionStateInside)
    {
        NSLog(@"%@",[NSString stringWithFormat:@"You are inside region %@", region.identifier]);
    }
    else if(state == CLRegionStateOutside)
    {
        NSLog(@"%@",[NSString stringWithFormat:@"You are outside region %@", region.identifier]);
    }
    else
    {
        return;
    }
}

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{
    if ([beacons count] == 0)
        return;

    NSString * message;
    UIColor * bgColor;
    CLBeacon * beacon = [beacons firstObject];

    switch (beacon.proximity) {
        case CLProximityUnknown:
            message = [NSString stringWithFormat:@"ProximityUnknown -- %ld", (long)beacon.proximity];
            bgColor = [UIColor blueColor];
            break;
        case CLProximityFar:
            message = [NSString stringWithFormat:@"ProximityFar -- %ld", (long)beacon.proximity];
            bgColor = [UIColor colorWithRed:.0f green:.0f blue:230.0f alpha:1.0f];
            break;
        case CLProximityNear:
            message = [NSString stringWithFormat:@"ProximityNear -- %ld", (long)beacon.proximity];
            bgColor = [UIColor orangeColor];
            break;
        case CLProximityImmediate:
        default:
            message = [NSString stringWithFormat:@"ProximityImmediate -- %ld", (long)beacon.proximity];
            bgColor = [UIColor redColor];
            break;
    }
    if (beacon.proximity != self.previousProximity)
    {
        [lblStatus setText:message];
        [self.view setBackgroundColor:bgColor];
        self.previousProximity = beacon.proximity;  
    }  
}

那么有什么方法可以在不知道uuid的情况下检测iBeacon吗?

注意:使用与 check This link 广播广播信号(虚拟信标)相同功能的示例应用程序。

非常感谢任何帮助。

在 iOS 中没有 public APIs 来检测信标而不首先至少知道信标的 ProximityUUID。这是设计使然——Apple 只希望您能够看到自己的信标,这意味着知道 ProximityUUID。

就是说,操作系统当然知道如何查看任何信标,并且 可能有私有 API 可以用来执行此操作。只需了解您不能使用私有 APIs 为 App Store 开发应用程序,因为 Apple 不会批准使用此类代码。您可以使用私有 APIs 创建一个实用程序来使用您自己的 iOS 设备,但是私有 APIs 可能会停止与任何 iOS 升级

一起工作

根据这些注意事项,使用 CoreLocation 可以定义一个通配符 CLBeaconRegion,该通配符可用于使用私有 API 查找任何信标。 See here 一种方法。

您需要使用 CoreBluetooth 库来扫描设备。从已发现设备列表中找到您的 iBeacon 后,您将查询 iBeacon 的服务和特征以查找 UUID。这是我的做法:

import CoreBluetooth
import CoreLocation

extension Data {

    public var hexString: String {
        var str = ""
        enumerateBytes { (buffer, index, stop) in
            for byte in buffer {
                str.append(String(format: "%02X", byte))
            }
        }
        return str
    }
}

class viewController: UIViewController, CLLocationManagerDelegate, CBCentralManagerDelegate, CGPeripheralDelegate {

    var locationManager: CLLocationManager = CLLocationManager()
    var myBeaconRegion: CLBeaconRegion!
    var centralManager: CBCentralManager!
    var discoveredPeripheral: CBPeripheral?

    override viewDidLoad() {

        centralManager = CBCentralManager(delegate: self, queue: nil)
    }

    func centralManagerDidUpdateState(_ central: CBCentralManager) {

        if central.state != .poweredOn {
            return
        }

        centralManager.scanForPeripherals(withServices: nil, options: [CBCentralManagerScanOptionAllowDuplicateKeys: true])
    }

    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String: Any], rssi RSSI: NSNumber) {

        if (RSSI.intValue > -15 || RSSI.intValue < -35) {
            return // With those RSSI values, probably not an iBeacon.
        }

        if peripheral != discoveredPeripheral {
            discoveredPeripheral = peripheral // Need to retain a reference to connect to the beacon.
            centralManager.connect(peripheral, options: nil)
            central.stopScan() // No need to scan anymore, we found it.
        }
    }

    func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {

        peripheral.discoverServices(nil)
    }

    func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) {

        discoveredPeripheral = nil
    }

    func peripheral(_ peripheral: CBPeripheral, didDiscoverServices error: Error?) {

        guard error == nil else {
            return
        }

        if let services = peripheral.services {
            for service in services {
                peripheral.discoverCharacteristics(nil, for: service)
            }
        }
    }

    func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error?) {

        guard error == nil else {
            return
        }

        if let characteristics = service.characteristics {
            for characteristic in characteristics {
                if characteristic.uuid.uuidString == "2B24" { // UUID
                    peripheral.readValue(for: characteristic)
                }
            }
        }
    }

    func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) {

        guard error == nil else {
            return;
        }

        if value = characteristic.value {
            // value will be a Data object with bits that represent the UUID you're looking for.
            print("Found beacon UUID: \(value.hexString)")
            // This is where you can start the CLBeaconRegion and start monitoring it, or just get the value you need.
        }
    }
