Sync

– sync:

The Initial Sync request performs a complete sync of your app data. It returns all the published entries and assets of the specified stack in response. The response also contains a sync token, which you need to store, since this token is used to get subsequent delta updates later.

- (void)sync:(void ( ^ ) ( SyncStack *BUILT_NULLABLE_P syncStack , NSError *BUILT_NULLABLE_P error ))completionBlock

Parameters

completionBlock

called synchronization is done.

Discussion

 //Obj-C
     [stack sync:^(SyncStack * _Nullable syncStack, NSError * _Nullable error) {

     }];

 //Swift
     stack.sync({ ( syncStack:SyncStack, error: NSError) in

     })

Declared In

Stack.h

– syncPaginationToken:completion:

If the result of the initial sync (or subsequent sync) contains more than 100 records, the response would be paginated. It provides pagination token in the response. However, you do not have to use the pagination token manually to get the next batch, the SDK does that automatically until the sync is complete. Pagination token can be used in case you want to fetch only selected batches. It is especially useful if the sync process is interrupted midway (due to network issues, etc.). In such cases, this token can be used to restart the sync process from where it was interrupted.

- (void)syncPaginationToken:(NSString *)token completion:(void ( ^ ) ( SyncStack *BUILT_NULLABLE_P syncResult , NSError *BUILT_NULLABLE_P error ))completionBlock

Parameters

token

Pagination token from where to perform sync

completionBlock

called synchronization is done.

Discussion

//Obj-C

NSString *token = @“blt129393939”; //Pagination token [stack syncPaginationToken:token completion:^(SyncStack * Nullable syncStack, NSError * Nullable error) {

}];

//Swift var token = @“blt129393939”; //Pagination token syncPaginationToken(token, completion: { ( syncStack:SyncStack, error: NSError) in

})

Declared In

Stack.h

– syncToken:completion:

You can use the sync token (that you receive after initial sync) to get the updated content next time. The sync token fetches only the content that was added after your last sync, and the details of the content that was deleted or updated.

- (void)syncToken:(NSString *)token completion:(void ( ^ ) ( SyncStack *BUILT_NULLABLE_P syncStack , NSError *BUILT_NULLABLE_P error ))completionBlock

Parameters

token

Sync token from where to perform sync

completionBlock

called synchronization is done.

Discussion

 //Obj-C

     NSString *token = @"blt129393939"; //Sync token
     [stack syncToken:token completion:^(SyncStack * _Nullable syncStack, NSError * _Nullable error) {

     }];

 //Swift
     var token = @"blt129393939"; //Sync token

Stack.h

Stack.h

– syncFrom:completion:

You can also initialize sync with entries published after a specific date. To do this, use sync Date and specify the start date as its value.
