    using UnityEngine.Events;
    
    public class RepeatButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler, IPointerExitHandler {
    
    	public bool invokeOnce = false;//是否只调用一次
    	private bool hadInvoke = false;//是否已经调用过
    
    	public float interval = 0.1f;//按下后超过这个时间则认定为"长按"
    	private bool isPointerDown = false;
    	private float recordTime;
    
    	public UnityEvent onPress = new UnityEvent();//按住时调用
    	public UnityEvent onRelease = new UnityEvent();//松开时调用
    
        public static RepeatButton Get(Transform trans)
        {
            if (trans.GetComponent<RepeatButton>() == null)
            {
                trans.gameObject.AddComponent<RepeatButton>();
            }
            return trans.GetComponent<RepeatButton>();
        }
        void Update () 
    	{
    		if (invokeOnce && hadInvoke) return;
    		if (isPointerDown)
    		{
    			if ((Time.time - recordTime) > interval)
    			{
    				onPress.Invoke();
    				hadInvoke = true;
                    recordTime = Time.time;
                }
    		}
    	}
    
    	public void OnPointerDown(PointerEventData eventData)
    	{
    		isPointerDown = true;
    		recordTime = Time.time;
    	}
    
    	public void OnPointerUp(PointerEventData eventData)
    	{
    		isPointerDown = false;
    		hadInvoke = false;
    		onRelease.Invoke();
    	}
    
    	public void OnPointerExit(PointerEventData eventData)
    	{
    		isPointerDown = false;
    		hadInvoke = false;
    		onRelease.Invoke();
    	}
    }

如何使用

RepeatButton.Get(m_trans.Find("BtnPar/BtnShang")).onPress.AddListener(()=> { OnBtnTianChe(EnTianCheDir.Shang); });
