描述

Unity raises this event when Player is unloading.

Add an event handler to this event if you want to react to Application.Unload calls. The event is raised after a call to Application.Unload is made, right before the unloading starts.

Note: Application.unloading event is only supported on iOS, Android, and Universal Windows Platform.

using UnityEngine;
using System.Collections;

// Unload Unity when the user clicks the button. Exit is not applied to the application.

public class ExampleClass : MonoBehaviour { void OnGUI() { if (GUI.Button(new Rect(10, 10, 200, 75), "Unload")) Application.Unload(); }

static void OnUnload() { Debug.Log("Unloading the Player"); }

[RuntimeInitializeOnLoadMethod] static void RunOnStart() { Application.unloading += OnUnload; } }
