Instance Property

previousServerChangeToken

The change token from a previous fetch operation.

Declaration

@property(nonatomic, copy) CKServerChangeToken *previousServerChangeToken;

Discussion

Assign the token you received previously from the fetchNotificationChangesCompletionBlock completion block to this property. Doing so yields only the notifications that have arrived since your last fetch operation. If you specify nil for this parameter, the operation starts fetching notifications at the beginning of the list and returns all but those that have already been marked as read.
