Main thread and external thread

When using Unity, if an object or function created using UnityEngine or UnityEngine.UI is called from an external thread, an exception occurs.

When a callback is called to the main thread, a crash may occur if numerous objects are created in the callback, synchronous form BACKND functions cause the game to stop temporarily, or if a heavy action takes place.

AppleLoginCallback

This is a handler that is called automatically when a token has been issued. It can be assigned as a variable for AppleLogin.

public delegate void AppleLoginCallback(string token);
private static AppleLoginCallback OnAppleLogin;

OnCloseButtonClick

This is a handler that is called when you quit Apple login with the button on the top right.

public delegate void CloseButtonClickCallback();
public static CloseButtonClickCallback OnCloseButtonClick;

Example

    public void StartAppleLogin() {
        #if UNITY_ANDROID || UNITY_EDITOR
        TheBackend.ToolKit.AppleLogin.Android.OnCloseButtonClick = () => {
            Debug.Log("The window has been closed");
        };
        
        TheBackend.ToolKit.AppleLogin.Android.AppleLogin("com.thebackend.testapp.applelogin", out var error, true, token => {
            Debug.Log("Token : " + token);            
            Debug.Log("A token has been issued. You can now log in.");

            // Warning! : Do not call synchronous methods as shown below.
            // var bro = Backend.BMember.AuthorizeFederation(token, FederationType.Apple);

            // Call asynchronous methods as shown below.

            Backend.BMember.AuthorizeFederation(token, FederationType.Apple, callback => { 
                Debug.Log("Apple login result : " + callback); 
            });
        });

        if (string.IsNullOrEmpty(error) == false) {
            Debug.Log("Error : " + error);
        }
        #endif
    }
