报错内容：

* Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘State restoration of CBCentralManager is only allowed for applications that have specified the “bluetooth-central” background mode’

解决方法：

在plist文件中添加蓝牙后台使用的模式

<key>UIBackgroundModes</key>

<array>

<string>bluetooth-central</string>

</array>

Required background modes 属性 即后台工作模式
