Class

CKServerChangeToken

An object that identifies a specific version of a record.

Declaration

@interface CKServerChangeToken : NSObject

Overview

You do not create instances of this class yourself. When fetching records using a CKFetchRecordChangesOperation object, the server provides one of these objects along with the record changes. The next time you fetch the records, pass the previous token to the server. Passing the previous token tells the server what portions of the records to fetch and return to your app.
