public GraphicRaycaster m_CanvasUI; public EventSystem eventSystem; private void Update()
{ if (Input.GetMouseButtonDown(0)) {
CheckSecondUI(Input.mousePosition);

/// <returns></returns>
public void CheckSecondUI(Vector2 pos)
{
List<GameObject> objList = new List<GameObject>();
PointerEventData eventData = new PointerEventData(eventSystem);
eventData.pressPosition = pos;
eventData.position = pos;

List<RaycastResult> list = new List<RaycastResult>();
CanvasUI.Raycast(eventData, list); if (list.Count > 0)
{ for (int i = 0; i < list.Count; i++)
{
Debug.Log(list[i].gameObject.name);
}
} else {
Debug.Log("没有UI");
}
