Question

我使用CBCentralManager，

检测到了外围设备

我使用的代码就是这个，

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self.navigationController setNavigationBarHidden: YES animated:NO];

    cbMgr = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
}


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


    //NSLog([NSString stringWithFormat:@"%@",[advertisementData description]]);

    NSLog (@"Discovered peripheral: %@", [peripheral name]);
    NSLog (@"Discovered peripheral identifier: %@", [peripheral identifier]);

    NSLog (@"peripheral services before connected: %@", [peripheral services]);
    NSLog (@"Discovered peripheral RSSI: %@", [peripheral RSSI]);
    NSLog (@"\n===============================================");

   // NSLog(@"adversting data %@",[NSString stringWithFormat:@"%@",[advertisementData description]]);
}

-(void)centralManager:(CBCentralManager *)central didRetrievePeripherals:(NSArray *)peripherals{
    NSLog(@"This is it!");
}

- (void)centralManagerDidUpdateState:(CBCentralManager *)central{
    NSString *messtoshow;

    switch (central.state) {
        case CBCentralManagerStateUnknown:
        {
            messtoshow=[NSString stringWithFormat:@"State unknown, update imminent."];
            break;
        }
        case CBCentralManagerStateResetting:
        {
            messtoshow=[NSString stringWithFormat:@"The connection with the system service was momentarily lost, update imminent."];
            break;
        }
        case CBCentralManagerStateUnsupported:
        {
            messtoshow=[NSString stringWithFormat:@"The platform doesn't support Bluetooth Low Energy"];
            break;
        }
        case CBCentralManagerStateUnauthorized:
        {
            messtoshow=[NSString stringWithFormat:@"The app is not authorized to use Bluetooth Low Energy"];
            break;
        }
        case CBCentralManagerStatePoweredOff:
        {
            messtoshow=[NSString stringWithFormat:@"Bluetooth is currently powered off."];
            break;
        }
        case CBCentralManagerStatePoweredOn:
        {
            messtoshow=[NSString stringWithFormat:@"Bluetooth is currently powered on and available to use."];
            [cbMgr scanForPeripheralsWithServices:nil options:nil];
            //[mgr retrieveConnectedPeripherals];

            //--- it works, I Do get in this area!

            break;
        }   

    }
}

现在我想要这样的细节，
公司编号：
信标类型：
接近UUID：
专业：
辅修：
测量功率：

是否有可能获得此详细信息，我尝试使用NSConcreteUUID来设置信标，但它不会返回信标数据（如预期的那样）..

很遗憾，您无法使用CoreBluetooth阅读iBeacon信息。 Apple使用这些API阻止访问iBeacon广告的原始数据。你可以在这里阅读有关这方面的全部细节：

访问其中一些数据的最佳方法是使用CoreLocation范围API，但您必须事先了解信标的PriximityUUID才能执行此操作。我怀疑这对您没有用的原因可能是因为您正在使用CoreBluetooth返回的蓝牙服务UUID来使用CoreLocation来定位具有给定ProximityUUID的信标。这不起作用，因为这两个UUID实际上是不同的。

同样，范围是您可以做的最好的，但您将无法读取companyId，beaconType或measuredPower字段。我担心Apple在iOS上阻止访问此信息的工作做得很彻底。
