using UnityEngine;
using UnityEngine.UI;

    // Use this for initialization
    void Start () {
    
    }
    
 
    void Update()
    {
        if (Input.GetMouseButtonDown(0)||(Input.touchCount >0 && Input.GetTouch(0).phase == TouchPhase.Began))
        {
#if IPHONE || ANDROID
            if (EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
#else
            if (EventSystem.current.IsPointerOverGameObject())
#endif
                Debug.Log("当前触摸在UI上");
            
            else 
                Debug.Log("当前没有触摸在UI上");
