- Attributes
Remarks
This constant can be used with the NSNotificationCenter to register a listener for this notification, also developers can use the strongly typed notification ObserveDidChange instead. This is an NSString instead of a string, because these values can be used as tokens in some native libraries instead of being used purely for their actual string content. The 'notification' parameter to the callback contains extra information that is specific to the notification type.
