ibeacon是基于地理位置的微定位技術(shù)担猛，區(qū)別于BLE收毫。
兩者無任何關(guān)系邑跪。ibeacon使用CoreLocation庫鹊碍，而BLE使用CoreBluetooth庫舆床。
開發(fā)ibeacon需要了解beacon三個(gè)標(biāo)識(shí)：
UUID：用來標(biāo)記某一類beacon
major：主要值虑绵，用于區(qū)別子類
minor：次要值丧蘸，用于區(qū)別子類類下一級
如果開發(fā)打卡功能瑟枫。則一般藍(lán)牙硬件都使用同一個(gè)UUID春霍，用于匹配此類beacon砸西，使用major和minor來區(qū)別不同教室。
使用之前需倒入：
import CoreLocation
同時(shí)info.plist文件添加定位權(quán)限：
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
NSLocationAlwaysAndWhenInUseUsageDescription
創(chuàng)建IbeaconManager類
直接上代碼：

// did centralManager enable notification
let BluetoothNotificationManagerEnable = "BabyNotificationAtCentralManagerEnable"
// 藍(lán)牙彈框是需要彈出
