NOTIFICATION MATCHING Registering to be a notification observer is especially versatile. via passing nil for both the identify parameter or the article parameter in addObserver(_:,selector:,name:,object:), you could request to obtain notifications with a given identify, for a particular item, or either. the next desk exhibits the impression of the identify and item parameters while changing into an observer:name item Notifications acquired "Name" item obtain simply notifications named identify for the article item "Name" nil obtain all notifications named identify for any item nil item obtain each notification for the thing item nil nil obtain each notification (not instructed) during this scenario, you need to be notified while any MyWhatsit item is edited.
