推荐答案
要使用CoreBluetooth，首先您的设备必须支持蓝牙4.0中的蓝牙低功耗。您无法通过iOS的UI连接到设备，您必须为它开发自己的UI，因为您的应用程序只需要连接到您感兴趣的服务的设备。
To use CoreBluetooth, first your device must support Bluetooth Low Energy in Bluetooth 4.0. You can't connect to the device through iOS's UI for LE, you will have to develop your own UI for it because your application need to connect to only the devices with the services that you are interested in.
之后，您可以在更新特征值时订阅设备通知，然后使用CoreBluetooth API读取值。如果设备具有可写入的特性，那么您的应用程序可以使用CoreBluetooth API写入特征。
After that, you can subscribe to notification of the device when a characteristic value is updated, and then read the value using CoreBluetooth API. If the device has a characteristic that can be written to, then your application can write to the characteristic using CoreBluetooth API.
这是一般的想法，希望能回答您的问题。
That's the general idea, hope that answers your question.
