LoginButtonDelegate

public protocol LoginButtonDelegate : AnyObject

Defines methods that allow you to handle different login statuses if you use the predefined LINE Login button by using the LoginButton class.

  • Called after the login action is started. Since LINE Login is an asynchronous operation, you might want to show an indicator or another visual effect to prevent the user from taking other actions.

    Declaration

    Swift

    func loginButtonDidStartLogin(_ button: LoginButton)

  • Called if the login action succeeds.

    Declaration

    Swift

    func loginButton(_ button: LoginButton, didSucceedLogin loginResult: LoginResult)

    Parameters

    button

    The button used to start the login action.
    loginResult

    The successful login result.

  • Called if the login action fails.

    Declaration

    Swift

    func loginButton(_ button: LoginButton, didFailLogin error: LineSDKError)

    Parameters

    button

    The button used to start the login action.
    error

    The strong typed LineSDKError of the failed login.

  • Warning

    Deprecated. Use the same delegate method which receives LineSDKError instead. It provides a strongly typed and consistent error for the login failure.

    Called if the login action fails.

    Declaration

    Swift

    func loginButton(_ button: LoginButton, didFailLogin error: Error)

    Parameters

    button

    The button used to start the login action.
    error

    The error of the failed login.
