你好！  
我想请问下，为什么通过蓝牙扫描的方式得到beacon之后，beacon的很多属性都是为null的，比如distance和macAddress，measuredPower，proximityUUID等

iOS自身的SDK限制了，通过蓝牙方式扫描无法获得proximityUUID等iBeacon相关信息。只能通过iBeacon方式扫描获取

好的，谢谢，那如果扫描指定区域的iBeacon，传入需要监测的region，一个ibeacon是不是就是表示一个region呢？region中需要指定的ProximityUUID是自定义的还是设备本身的呢？

一个region是proximityUUID, major, minor的组合。ProximityUUID是自定义的，更多信息可以看看我们的[FAQ](http://wiki.aprbrother.com/wiki/WeChat_FAQ#Q:.E4.BB.80.E4.B9.88.E6.98.AFiBeacon_ID)

你可以参考这个[例子](https://github.com/AprilBrother/AprilBeacon-iOS-SDK/blob/master/AprilBeaconDemo/AprilBeaconDemo/ABBeaconViewController.m)
