由于appstore在iOS 13之后修改了审核规则，需要在Plist 文件中 新增 NSBluetoothAlwaysUsageDescription 而不是 Privacy - Bluetooth Always Usage Description .
***********官方说明如下*********
Important
If your app has a deployment target earlier than iOS 13, add the NSBluetoothPeripheralUsageDescription key to your app’s Information Property List file in addition to this key.
