  • Refresh the user’s access and ID tokens if they have expired or are about to expire.

    Declaration

    Swift

    func refreshTokensIfNeeded() async throws -> GIDGoogleUser

    Objective-C

    - (void)refreshTokensIfNeededWithCompletion:
    (nonnull void (^)(GIDGoogleUser *_Nullable, NSError *_Nullable))completion;

    Parameters

    completion

    A completion block that takes a GIDGoogleUser or an error if the attempt to refresh tokens was unsuccessful. The block will be called asynchronously on the main queue.

  • Starts an interactive consent flow on iOS to add new scopes to the user’s grantedScopes.

    The completion will be called at the end of this process. If successful, a GIDSignInResult instance will be returned reflecting the new scopes and saved sign-in state will be updated.

    Declaration

    Swift

    func addScopes(_ scopes: [String], presenting presentingViewController: UIViewController) async throws -> GIDSignInResult

    Objective-C

    - (void)addScopes:(nonnull NSArray<NSString *> *)scopes
    presentingViewController:
        (nonnull UIViewController *)presentingViewController
                  completion:(nullable void (^)(GIDSignInResult *_Nullable,
                                                NSError *_Nullable))completion;

    Parameters

    scopes

    The scopes to ask the user to consent to.

    completion

    The optional block that is called on completion. This block will be called asynchronously on the main queue.

  • Starts an interactive consent flow on macOS to add new scopes to the user’s grantedScopes.

    The completion will be called at the end of this process. If successful, a GIDSignInResult instance will be returned reflecting the new scopes and saved sign-in state will be updated.

    Declaration

    Swift

    func addScopes(_ scopes: [String], presentingWindow: Any!) async throws -> GIDSignInResult

    Objective-C

    - (void)addScopes:(nonnull NSArray<NSString *> *)scopes
    presentingWindow:(id)presentingWindow
          completion:(nullable void (^)(GIDSignInResult *_Nullable,
                                        NSError *_Nullable))completion;

    Parameters

    scopes

    An array of scopes to ask the user to consent to.
    presentingWindow

    The window used to supply presentationContextProvider for ASWebAuthenticationSession.
    completion

    The optional block that is called on completion. This block will be called asynchronously on the main queue.
