Application.quitting

描述

Unity raises this event when the Player application is quitting.

向此事件添加一个事件处理程序，以便接收关于应用程序退出的通知。

Note: The Application._quitting event is raised when the quitting process cannot be cancelled. Examples of when this event is not raised are: when the Player is forced to quit or if there is a crash.

iOS applications are usually suspended because they don't quit unlike non-iOS apps. You should select Exit on Suspend in Player settings for iOS builds to make the game quit and not suspend, otherwise the application quit event might not be triggered. If Exit on Suspend is not enabled, then the quit events are triggered to OnApplicationPause instead.

On UWP Apps, there's no application quit event; therefore, consider using OnApplicationFocus event when focusStatus equals false.

To prevent the player application from quitting, refer to the Application.wantsToQuit event.

using UnityEngine;

public class PlayerQuitExample
{
    static void Quit()
    {
        Debug.Log("Quitting the Player");
    }

    [RuntimeInitializeOnLoadMethod]
    static void RunOnStart()
    {
        Application.quitting += Quit;
    }
}
