 获取当前点击的是不是UI

    void Update()
    {
        //场景中必须有EventSystem
        if (Input.GetMouseButtonDown(0))
        {
            if (EventSystem.current.IsPointerOverGameObject() || GUIUtility.hotControl != 0)
            {
              Debug.Log("单击到了UI");
            }
            else
            {
              Debug.Log("没有单击到UI");
            }
        }
    }
