可能会帮助您.而且，CoreBluetooth仅允许您访问低功耗蓝牙设备.如果需要加密，则可以配对这些设备，但通常不需要.但是，没有API可以列出已配对的设备-您需要发现提供感兴趣的服务的设备并列出列表，如果需要，可以在应用程序中使用自己的UI.确定目标设备后，即可启动连接.

Might help you. More over, CoreBluetooth only allows you to access Bluetooth Low Energy devices. You can pair these devices if you need encryption but typically you don't. However, there is no API to list the paired devices - you need to discover the device(s) that are offering the service you are interested in and present a list, if necessary using your own UI in your app. Once you have identified the target device you can initiate a connection.
