Checking CBPeripheralManager.authorizationStatus() now that it is deprecated

问题

CBPeripheralManager.authorizationStatus() and CBPeripheralManagerAuthorizationStatus are deprecated based on apple docs. What is the proper way of checking whether user has granted permission to use bluetooth in background now?

CBPeripheralManagerDelegate has peripheralManagerDidUpdateState but that never returns unauthorized regardless of whether user granted the permission or not, instead it only returns poweredOn or poweredOff

回答1:

CBCentralManager and CBPeripheralManager inherit from CBManager.

As of iOS 13, CBManager has an authorization property. You can check this for .allowedAlways.

You can use if #available(iOS 13.0, *) to conditionally use authorization on iOS 13 and later

回答2:

Please note that Apple changed the CBManager API between 13.0 and 13.1

• In 13.0 authorization is an instance property.
• In 13.1 authorization is a type (class) property.

The 13.0 instance property has been marked as deprecated.
