CKRecordZoneNotificationMBS class

Super class: CKNotificationMBS

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
class CloudKit MBS Mac64bit Plugin 16.5 Yes No No Yes, macOS only No
Function: A notification that is caused by changes to the contents of a record zone.
Zone-related changes occur when existing records in the zone are modified, when new records are added, and when existing records are deleted. Use instances of this class to determine which zone triggered the notification.

You do not create instances of this class directly. When your app receives a push notification, call the notificationFromRemoteNotificationDictionary method of CKNotificationMBS to generate a notification object of the appropriate type. You can also fetch previously delivered notifications from a container using a CKFetchNotificationChangesOperationMBS object. If the notification was triggered due to a record zone change, the operation object delivers an instance of CKRecordZoneNotificationMBS with its notificationType property set to CKNotificationTypeRecordZoneMBS. Use the record zone notification object to get the record zone information and other push-related data.

If a push notification’s payload is too large, pieces of data may be dropped until the payload meets the allowed size limit. The data that alerts the user is the most important and is dropped last. Data values in this class are among the first to be dropped, with values being dropped in the following order:

1. containerIdentifier—defined in the CKNotification class.
2. recordZoneID
3. Other properties of the CKNotification class.
Subclass of the CKNotificationMBS class.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
