using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

核心代碼

    public EventSystem eventSystem; //ui 中的 EventSystem 組件
    public GraphicRaycaster gRaycaster; //canvas  下的 GraphicRaycaster組件


    void OutPut(Vector2 v2)
    {
        List<RaycastResult> raycasts = new List<RaycastResult>();
        PointerEventData ped = new PointerEventData(eventSystem);
        ped.position = v2;
        gRaycaster.Raycast(ped, raycasts);
        foreach (var raycast in raycasts) // 輸出獲取到底UI對(duì)象
        {
            print(raycast.gameObject.name); 
        }
    }

補(bǔ)充
如果目標(biāo)UI不想被采集到，可以通過取消勾選 Raycast Target 選項(xiàng)
