react-native-beacons-manager无法检测任何信标iOS

Question

我已经按照示例了解如何在这里使用react-native-beacons-manager：https://github.com/MacKentoch/react-native-beacons-manager/blob/master/examples/samples/monitoringAndRanging.ios.md 但即使我有一个信标设备，我也无法检测到该地区的任何信标。我在硬编码区域很困惑：

const region = {
       identifier: 'Estimotes',
       uuid: 'B9407F30-F5F8-466E-AFF9-25556B57FE6D'
   }; 

这些标识符和UUID是什么？使用它是否安全，或者我应该在某处开始检测信标？这是我的相关代码，我省略了一些不相关的代码：

import Beacons from 'react-native-beacons-manager';

class HomeTab extends Component {
  constructor(props) {
   super(props);
   var ds = new ListView.DataSource({
    rowHasChanged: (r1, r2) => r1 !== r2 }
  );
   this.state = {
     region: {
       latitude: LATITUDE,
       longitude: LONGITUDE,
       latitudeDelta: LATITUDE_DELTA,
       longitudeDelta: LONGITUDE_DELTA,
        dataSource: ds.cloneWithRows([])
     }
   };
 }

componentWillMount(){

     Beacons.requestAlwaysAuthorization();

     const region = {
       identifier: 'Estimotes',
       uuid: 'B9407F30-F5F8-466E-AFF9-25556B57FE6D'
   };


   Beacons.startMonitoringForRegion(region) // or like  < v1.0.7: .startRangingBeaconsInRegion(identifier, uuid)
   .then(() => console.log('Beacons monitoring started succesfully'))
   .catch(error => console.log(`Beacons monitoring not started, error: ${error}`));
   // Range for beacons inside the region
   Beacons.startRangingBeaconsInRegion(region) // or like  < v1.0.7: .startRangingBeaconsInRegion(identifier, uuid)
   .then(() => console.log('Beacons ranging started succesfully'))
   .catch(error => console.log(`Beacons ranging not started, error: ${error}`));
   // update location to ba able to monitor:
   Beacons.startUpdatingLocation();
 }

componentDidMount(){
 this.beaconsDidRangeEvent = DeviceEventEmitter.addListener(
       'beaconsDidRange',
       (data) => {
         console.log('beaconsDidRange data: ', data);

       }
     );

  this.beaconsDidRangeEvent = Beacons.BeaconsEventEmitter.addListener(
    'beaconsDidRange',
    (data) => {
      console.log('beaconsDidRange data: ', data);

    }
  );

     // monitoring events
     this.regionDidEnterEvent = Beacons.BeaconsEventEmitter.addListener(
       'regionDidEnter',
       (data) => {
         console.log('monitoring - regionDidEnter data: ', data);

       }
     );

}
}
