RLMSyncUser

@interface RLMSyncUser : NSObject

A RLMSyncUser instance represents a single Realm Object Server user account.

A user may have one or more credentials associated with it. These credentials uniquely identify the user to the authentication provider, and are used to sign into a Realm Object Server user account.

Note that user objects are only vended out via SDK APIs, and cannot be directly initialized. User objects can be accessed from any thread.

  • A dictionary of all valid, logged-in user identities corresponding to their user objects.

    Declaration

    Objective-C

    + (nonnull NSDictionary<NSString *, RLMSyncUser *> *)allUsers;

  • The logged-in user. nil if none exists.

    Warning

    Throws an exception if more than one logged-in user exists.

    Declaration

    Objective-C

    + (nullable RLMSyncUser *)currentUser;

Lifecycle

  • Create, log in, and asynchronously return a new user object, specifying a custom timeout for the network request and a custom queue to run the callback upon. Credentials identifying the user must be passed in. The user becomes available in the completion block, at which point it is ready for use.

    Declaration

    Objective-C

    + (void)logInWithCredentials:(nonnull RLMSyncCredentials *)credentials
               authServerURL:(nonnull NSURL *)authServerURL
                     timeout:(NSTimeInterval)timeout
               callbackQueue:(nonnull dispatch_queue_t)callbackQueue
                onCompletion:(nonnull RLMUserCompletionBlock)completion;
    Show on GitHub

  • Create, log in, and asynchronously return a new user object.

    If the login completes successfully, the completion block will invoked with a RLMSyncUser object representing the logged-in user. This object can be used to open synchronized Realms. If the login fails, the completion block will be invoked with an error.

    The completion block always runs on the main queue.

    Declaration

    Objective-C

    + (void)logInWithCredentials:(nonnull RLMSyncCredentials *)credentials
               authServerURL:(nonnull NSURL *)authServerURL
                onCompletion:(nonnull RLMUserCompletionBlock)completion;

    Parameters

    credentials

    A credentials value identifying the user to be logged in.
    authServerURL

    The URL of the authentication server (e.g. http://realm.example.org:9080).
    completion

    A callback block that returns a user object or an error, indicating the completion of the login operation.

  • Returns the default configuration for the user. The default configuration points to the default query-based Realm on the server the user authenticated against.

    Declaration

    Objective-C

    - (nonnull RLMRealmConfiguration *)configuration;
    Show on GitHub

  • Create a query-based configuration instance for the given url.

    Declaration

    Objective-C

    - (nonnull RLMRealmConfiguration *)configurationWithURL:(nullable NSURL *)url;

    Parameters

    url

    The unresolved absolute URL to the Realm on the Realm Object Server, e.g. realm://example.org/~/path/to/realm. Unresolved means the path should contain the wildcard marker ~, which will automatically be filled in with the user identity by the Realm Object Server.

    Return Value

    A default configuration object with the sync configuration set to use the given URL.

                                        (_Bool)fullSynchronization;

    Parameters

    url

    The unresolved absolute URL to the Realm on the Realm Object Server, e.g. realm://example.org/~/path/to/realm. Unresolved means the path should contain the wildcard marker ~, which will automatically be filled in with the user identity by the Realm Object Server.
    fullSynchronization

    If YES, all objects in the server Realm are automatically synchronized, and the query subscription methods cannot be used.

    Return Value

    A default configuration object with the sync configuration set to use the given URL and options.

     fullSynchronization:(_Bool)fullSynchronization
     enableSSLValidation:(_Bool)enableSSLValidation
               urlPrefix:(nullable NSString *)urlPrefix;

    Parameters

    url

    The unresolved absolute URL to the Realm on the Realm Object Server, e.g. realm://example.org/~/path/to/realm. Unresolved means the path should contain the wildcard marker ~, which will automatically be filled in with the user identity by the Realm Object Server.
    fullSynchronization

    If YES, all objects in the server Realm are automatically synchronized, and the query subscription methods cannot be used.
    enableSSLValidation

    If NO, invalid SSL certificates for the server will not be rejected. THIS SHOULD NEVER BE USED IN PRODUCTION AND EXISTS ONLY FOR TESTING PURPOSES.
    urlPrefix

    A prefix which is prepending to URLs constructed for the server. This should normally be nil, and customized only to match corresponding settings on the server.

    Return Value

    A default configuration object with the sync configuration set to use the given URL and options.

  • Log a user out, destroying their server state, unregistering them from the SDK, and removing any synced Realms associated with them from on-disk storage on next app launch. If the user is already logged out or in an error state, this method does nothing.

    This method should be called whenever the application is committed to not using a user again unless they are recreated. Failing to call this method may result in unused files and metadata needlessly taking up space.

    Declaration

    Objective-C

    - (void)logOut;
    Show on GitHub

  • An optional error handler which can be set to notify the host application when the user encounters an error. Errors reported by this error handler are always RLMSyncAuthErrors.

    Note

    Check for RLMSyncAuthErrorInvalidAccessToken to see if the user has been remotely logged out because its refresh token expired, or because the third party authentication service providing the user’s identity has logged the user out.

    Warning

    Regardless of whether an error handler is installed, certain user errors will automatically cause the user to enter the logged out state.

  • Change a user’s password using a one-time password reset token.

    By default, the password reset email sent by ROS will link to a web site where the user can select a new password, and the app will not need to call this method. If you wish to instead handle this within your native app, you must change the baseURL in the server configuration for PasswordAuthProvider to a scheme registered for your app, extract the token from the URL, and call this method after prompting the user for a new password.

    Warning

    Changing a user’s password using an authentication server that doesn’t use HTTPS is a major security flaw, and should only be done while testing.

    Declaration

    Objective-C

    + (void)completePasswordResetForAuthServer:(nonnull NSURL *)serverURL

  • Create a permission offer for a Realm.

    A permission offer is used to grant access to a Realm this user manages to another user. Creating a permission offer produces a string token which can be passed to the recepient in any suitable way (for example, via e-mail).

    The operation will take place asynchronously. The token can be accepted by the recepient using the -[RLMSyncUser acceptOfferForToken:callback:] method.

    See

    acceptOfferForToken:callback:

    Declaration

    Objective-C

    - (void)createOfferForRealmAtURL:(nonnull NSURL *)url
                     accessLevel:(RLMSyncAccessLevel)accessLevel
                      expiration:(nullable NSDate *)expirationDate
                        callback:
                            (nonnull RLMPermissionOfferStatusBlock)callback;

    Parameters

    url

    The URL of the Realm for which the permission offer should pertain. This may be the URL of any Realm which this user is allowed to manage. If the URL has a ~ wildcard it will be replaced with this user’s user identity.
    accessLevel

    What access level to grant to whoever accepts the token.
    expirationDate

    Optionally, a date which indicates when the offer expires. If the recepient attempts to accept the offer after the date it will be rejected.
    callback

    A callback indicating whether the operation succeeded or failed. If it succeeded the token will be passed in as a string.

  • Accept a permission offer.

    Pass in a token representing a permission offer. The operation will take place asynchronously. If the operation succeeds, the callback will be passed the URL of the Realm for which the offer applied, so the Realm can be opened.

    The token this method accepts can be created by the offering user through the -[RLMSyncUser createOfferForRealmAtURL:accessLevel:expiration:callback:] method.

    See

    createOfferForRealmAtURL:accessLevel:expiration:callback:

    Declaration

    Objective-C

    Show on GitHub

  • Revoke a permission offer.

    Pass in a token representing a permission offer which was created by this user. The operation will take place asynchronously. If the operation succeeds, the callback will be passed the URL of the Realm for which the offer was revoked. After this operation completes, the token can no longer be accepted by the recipient.

    See

    createOfferForRealmAtURL:accessLevel:expiration:callback:

    Declaration
