Question

有没有办法找出altBeacon的主要和次要值？我正在使用这个库（https://github.com/CharruaLab/AltBeacon）来检测附近的BLE设备（无论它是否是信标）。检测到信标，我知道他们的uuids。我可以使用iOS CoreBluetooth框架提取主要和次要值吗？

更新：代码似乎很好。看起来找出主要或次要的唯一方法是请求信标的数据，因为它是在下面接受的答案中完成的。但在这种情况下，信标本身并不一定会对你做出回应。

仅适用于iBeacon：

在下面覆盖CLLocationManager委托方法，当您能够检测到信标时，此方法将会调用。

-(void)locationManager:(CLLocationManager*)manager
       didRangeBeacons:(NSArray*)beacons
              inRegion:(CLBeaconRegion*)region {
    // Beacon found!

    CLBeacon *foundBeacon = [beacons firstObject];

    // You can retrieve the beacon data from its properties
    NSString *uuid = foundBeacon.proximityUUID.UUIDString;
    NSString *major = [NSString stringWithFormat:@"%@", foundBeacon.major];
    NSString *minor = [NSString stringWithFormat:@"%@", foundBeacon.minor];
}

要使用Core位置框架检测信标，您需要在viewDidLoad方法中添加以下代码。

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    // Initialize location manager and set ourselves as the delegate
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;

    // Create a NSUUID with the same UUID as the broadcasting beacon
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@"XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"];

    // Setup a new region with that UUID and same identifier as the broadcasting beacon
    self.myBeaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
                                                             identifier:@"com.app.identifier"];

    // Tell location manager to start monitoring for the beacon region
    [self.locationManager startMonitoringForRegion:self.myBeaconRegion];

    // Check if beacon monitoring is available for this device
    if (![CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]]) {

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Monitoring not available" message:nil delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil]; 
        [alert show]; 
    }
}

对于蓝牙设备：

使用两个代理CBCentralManagerDelegate和CBPeripheralDelegate

扩展视图控制器

在viewDidLoad创建CBCentralManager对象。

_centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];

并覆盖以下方法（scan方法除外）：

- (void)centralManagerDidUpdateState:(CBCentralManager *)central {
    if (central.state != CBCentralManagerStatePoweredOn) {
        return;
    }
    // The state must be CBCentralManagerStatePoweredOn...
    // ... so start scanning
    [self scan];
}

- (void) scan {

    // UUID for peripheral services
    [self.centralManager scanForPeripheralsWithServices:[NSArray arrayWithObject:[CBUUID UUIDWithString:@"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX"]] options:nil];
    NSLog(@"Scanning started");
}

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI {

    NSLog(@"Discovered %@ at %@", peripheral.name, RSSI);

    if (self.discoveredPeripheral != peripheral) {

        // Save a local copy of the peripheral, so CoreBluetooth doesn't get rid of it
        self.discoveredPeripheral = peripheral;

        // And connect
        NSLog(@"Connecting to peripheral %@", peripheral.UUID);
        [self.centralManager connectPeripheral:peripheral options:nil];
    }
}

- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral {
    NSLog(@"Peripheral Connected");

    // Stop scanning
    [self.centralManager stopScan];
    NSLog(@"Scanning stopped");

    // Make sure we get the discovery callbacks
    peripheral.delegate = self;
    [peripheral discoverServices:nil];
}
