A notification that is posted when an accessory is disconnected and no longer available for your application to use.
- iOS 3.0+
- macOS 10.13+
- tvOS 10.0+
The notification object is the shared accessory manager. The
user dictionary contains an
EAAccessory, whose value is the
EAAccessory object representing the accessory that was disconnected. Before delivery of this notification can occur, you must call the
register method to let the system know you are interested in receiving this notification.
If your accessory manager has a delegate, the delegate can use the
accessory method to receive this notification instead.
