判断当前点击屏幕位置是否UI组件

判断当前点击位置是否是UI组件，避免在点击按钮时，还继续屏幕其他操作

using System.Collections;

using UnityEngine;
using UnityEngine.EventSystems;

public class ARDraw : MonoBehaviour
{
 void Start()
    {
    }
    
void Update()
    {
    }

  private bool IsPointerOverUIObject()
    {
        //判断是否点击的是UI，有效应对安卓没有反应的情况，true为UI
        PointerEventData eventDataCurrentPosition = new PointerEventData(EventSystem.current);
        eventDataCurrentPosition.position = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
        List<RaycastResult> results = new List<RaycastResult>();
        EventSystem.current.RaycastAll(eventDataCurrentPosition, results);
        return results.Count > 0;
    }
