推荐答案

您可以使用蓝牙低耗能的（BTLE）接口。每当用户禁用/启用蓝牙设置，您将得到更新。检查<一个href=\"https://developer.apple.com/library/mac/documentation/CoreBluetooth/Reference/CBCentralManagerDelegate_Protocol/translated_content/CBCentralManagerDelegate.html#//apple_ref/occ/intfm/CBCentralManagerDelegate/centralManagerDidUpdateState%3a\"相对=nofollow> CBCentralManagerDelegate协议参考。当然，你也可以检查<一个href=\"https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/CBCentralManager_Class/translated_content/CBCentralManager.html#//apple_ref/occ/instp/CBCentralManager/state\"相对=nofollow>状态

You can use Bluetooth Low Energy's (BTLE) interface. You will get updates whenever an user disables/enables Bluetooth in settings. Check the CBCentralManagerDelegate Protocol Reference. And of course you can also check the state
