Overview

TICDSDocumentSyncManager describes the generic behavior provided by an Application Sync Manager in the TICoreDataSync framework.

The Application Sync Manager is responsible for application-wide synchronization settings. You typically have only one in an application.

Don’t instantiate this class directly, but instead use one of the subclasses:

  1. TICDSFileManagerBasedApplicationSyncManager
  2. TICDSDropboxSDKBasedApplicationSyncManager

You must register the application sync manager before you can use it to perform any other tasks, or register any documents.

Class Methods

defaultApplicationSyncManager

Returns an application-wide sync manager.

+ (id)defaultApplicationSyncManager

Return Value

The default application-wide sync manager (if one doesn’t exist, it will be created).

Discussion

Use this method to get the default application sync manager. If this is the first time you’ve requested one, a new one will be created.

Don’t call this method on TICDSApplicationSyncManager; if you do, you’ll receive a generic application sync manager object. Instead call it on one of the subclasses, for example [TICDSFileManagerBasedApplicationSyncManager defaultSyncManager].

Declared In

TICDSApplicationSyncManager.h

setDefaultApplicationSyncManager:

Set the application-wide sync manager.

+ (void)setDefaultApplicationSyncManager:(TICDSApplicationSyncManager *)aSyncManager

Parameters

aSyncManager

The new sync manager to set as the application-wide default.

Discussion

Use this method if you need to release an existing default manager, or wish to use a different default one for some reason.

Declared In

TICDSApplicationSyncManager.h

Instance Methods

applicationRegistrationOperation

Returns an application registration operation.

- (TICDSApplicationRegistrationOperation *)applicationRegistrationOperation

Return Value

A correctly-configured subclass of TICDSApplicationRegistrationOperation.

Discussion

Subclasses of TICDSApplicationSyncManager use this method to return a correctly-configured application registration operation for their particular sync method.

Declared In

TICDSApplicationSyncManager.h

cancelRegistrationWithoutProvidingEncryptionPassword

Cancel registration after being asked for an encryption password.

- (void)cancelRegistrationWithoutProvidingEncryptionPassword

Discussion

Use this method to cancel registration if the user is unable to provide the correct encryption password.

Using this method at other times will result in undefined behavior.

Declared In

TICDSApplicationSyncManager.h

configureWithDelegate:globalAppIdentifier:uniqueClientIdentifier:description:userInfo:

Configure an application but don’t immediately register it.

- (void)configureWithDelegate:(id<TICDSApplicationSyncManagerDelegate>)aDelegate globalAppIdentifier:(NSString *)anAppIdentifier uniqueClientIdentifier:(NSString *)aClientIdentifier description:(NSString *)aClientDescription userInfo:(NSDictionary *)someUserInfo

Parameters

aDelegate

The object you wish to be notified regarding application-related sync information; this object must conform to the TICDSApplicationSyncManagerDelegate protocol, which includes some required methods.

anAppIdentifier

The identification string used to identify the synchronization information across multiple clients. If you wish to be able to synchronize Mac and iOS, this app identifier should be the same on both platforms. This identifier will also be used as the root level of the remote file structure.

aClientIdentifier

An identification string for this client. Every client wishing to synchronize must have a string to identify itself (i.e., the application instance on a machine) uniquely. You would typically create a UUID string the first time your app is launched and store this in preferences.

aClientDescription

A human-readable string used to identify this client, e.g. the computer name.

someUserInfo

A dictionary of information that will be saved throughout all future synchronizations. Because this information is saved in a plist, everything in the dictionary must be archivable.

Discussion

Use this method to configure the sync manager in environments where you may not have a permanent internet connection, such as an iOS device, or a desktop WebDAV client, etc.

This will configure everything necessary to track changes made by the user. When you wish to initiate a sync, or perform any other task, you’ll need to call the registerConfiguredApplicationSyncManager method first to initiate registration.

Declared In

TICDSApplicationSyncManager.h

continueRegisteringWithEncryptionPassword:

Continue registering an application for the first time specifying whether to use encryption, or an existing application that requires an encryption password.

- (void)continueRegisteringWithEncryptionPassword:(NSString *)aPassword

Parameters

aPassword

The password to use, or nil to specify no encryption on a new application registration.

Discussion

If you are requesting the registration process continue for a new application, and do not want to enable encryption, specify nil for the password, otherwise supply the password the user wishes to use.

If you are requesting the registration process continue for an existing application that requires an encryption password, you must specify a password other than nil.

Declared In

TICDSApplicationSyncManager.h

deleteDocumentWithIdentifier:

Delete the specified document, if it exists, from the remote.

- (void)deleteDocumentWithIdentifier:(NSString *)anIdentifier

Parameters

anIdentifier

The identifier of the document to be deleted.

Discussion

As well as delegate methods indicating the status of the overall deletion process, applicationSyncManager:willDeleteDirectoryForDocumentWithIdentifier: and applicationSyncManager:didDeleteDirectoryForDocumentWithIdentifier: methods will be called either side of the deletion of the actual document directory.

Declared In

TICDSApplicationSyncManager.h

documentDeletionOperationForDocumentWithIdentifier:

Returns an operation to delete a document with a given identifier.

- (TICDSDocumentDeletionOperation *)documentDeletionOperationForDocumentWithIdentifier:(NSString *)anIdentifier

Parameters

anIdentifier

The unique synchronization identifier of the document to delete.

Return Value

A correctly-configured subclass of TICDSDocumentDeletionOperation.

Discussion

Subclasses of TICDSApplicationSyncManager use this method to return a correctly-configured document deletion operation for their particular sync method.

Declared In

TICDSApplicationSyncManager.h

listOfApplicationRegisteredClientsOperation

Returns an operation to fetch a list of registered clients for an application.

- (TICDSListOfApplicationRegisteredClientsOperation *)listOfApplicationRegisteredClientsOperation

Return Value

A correctly-configured subclass of TICDSListOfApplicationRegisteredClientsOperation.

Discussion

Subclasses of TICDSApplicationSyncManager use this method to return a correctly-configured operation for their particular sync method.

Declared In

TICDSApplicationSyncManager.h

listOfPreviouslySynchronizedDocumentsOperation

Returns an operation to fetch a list of previously synchronized documents.

- (TICDSListOfPreviouslySynchronizedDocumentsOperation *)listOfPreviouslySynchronizedDocumentsOperation

Return Value

A correctly-configured subclass of TICDSListOfPreviouslySynchronizedDocumentsOperation.

Discussion

Subclasses of TICDSApplicationSyncManager use this method to return a correctly-configured list of documents operation for their particular sync method.

Declared In

TICDSApplicationSyncManager.h

registerConfiguredApplicationSyncManager

Register an application that has already been pre-configured.

- (void)registerConfiguredApplicationSyncManager

Discussion

Use this method to register an application sync manager that you have already configured using the configureWithDelegate:globalAppIdentifier:uniqueClientIdentifier:description:userInfo: method.

Declared In

TICDSApplicationSyncManager.h

registerWithDelegate:globalAppIdentifier:uniqueClientIdentifier:description:userInfo:

Register an application ready for future synchronization.

- (void)registerWithDelegate:(id<TICDSApplicationSyncManagerDelegate>)aDelegate globalAppIdentifier:(NSString *)anAppIdentifier uniqueClientIdentifier:(NSString *)aClientIdentifier description:(NSString *)aClientDescription userInfo:(NSDictionary *)someUserInfo

Parameters

aDelegate

The object you wish to be notified regarding application-related sync information; this object must conform to the TICDSApplicationSyncManagerDelegate protocol, which includes some required methods.

anAppIdentifier

The identification string used to identify the synchronization information across multiple clients. If you wish to be able to synchronize Mac and iOS, this app identifier should be the same on both platforms. This identifier will also be used as the root level of the remote file structure.

aClientIdentifier

An identification string for this client. Every client wishing to synchronize must have a string to identify itself (i.e., the application instance on a machine) uniquely. You would typically create a UUID string the first time your app is launched and store this in preferences.

aClientDescription

A human-readable string used to identify this client, e.g. the computer name.

someUserInfo

A dictionary of information that will be saved throughout all future synchronizations. Because this information is saved in a plist, everything in the dictionary must be archivable.

Discussion

Use this method to register the sync manager ready for document registration and synchronization (via TICDSDocumentSyncManager objects).

This will automatically spawn a TICDSApplicationRegistrationOperation, and notify you of progress through the TICDSApplicationSyncManagerDelegate methods.

If this is the first time you have registered a client with this app identifier, registration will automatically create the file structure necessary at the remote end for this and other clients to synchronize. See [TICDSUtilities remoteGlobalAppDirectoryHierarchy] for the structure that will be created.
