I would like to detect whether an iOS device has Bluetooth enabled so that I can prevent the CoreBluetooth library from prompting the app user to enable it. I am NOT looking to check the state of the CBCentralManager; I just want to prevent the blue popup box so that it doesn't annoy my users.

如果没有对话框，您将无法在应用程序中使用 CoreBluetooth。所以，如果你想一起阻止它，你不能。

如果您只是想阻止他们是否关闭了蓝牙，那么首先检查 CBCentralManager 的状态是正确的方法（即检查它是否 == CBCentralManagerStatePoweredOff）。
