双击直接利用的eventData.clickCount实现，而长按则是在PointerDown的时候记录时间，然后在Update里判断时间即可，由于代码比较简单，直接上源码。

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; using UnityEngine.UI; public class UIButton : Button { protected UIButton() { m_onDoubleClick = new ButtonClickedEvent(); m_onLongPress = new ButtonClickedEvent(); } private ButtonClickedEvent m_onLongPress; public ButtonClickedEvent OnLongPress { get { return m_onLongPress; } set { m_onLongPress = value; } } private ButtonClickedEvent m_onDoubleClick; public ButtonClickedEvent OnDoubleClick { get { return m_onDoubleClick; } set { m_onDoubleClick = value; } } private bool m_isStartPress = false; private float m_curPointDownTime = 0f; private float m_longPressTime = 1f; private bool m_longPressTrigger = false; void Update () { if (m_isStartPress && !m_longPressTrigger) { if (Time.time > m_curPointDownTime + m_longPressTime) { m_longPressTrigger = true; m_isStartPress = false; if (m_onLongPress != null) { m_onLongPress.Invoke(); } } } } public override void OnPointerDown(PointerEventData eventData) { base.OnPointerDown(eventData); m_curPointDownTime = Time.time; m_isStartPress = true; m_longPressTrigger = false; } public override void OnPointerUp(PointerEventData eventData) { base.OnPointerUp(eventData); m_isStartPress = false; m_longPressTrigger = false; } public override void OnPointerExit(PointerEventData eventData) { base.OnPointerExit(eventData); m_isStartPress = false; m_longPressTrigger = false; } public override void OnPointerClick(PointerEventData eventData) { //base.OnPointerClick(eventData); if (!m_longPressTrigger) { if (eventData.clickCount == 1) { onClick.Invoke(); } else if (eventData.clickCount == 2) { if (m_onDoubleClick != null) { m_onDoubleClick.Invoke(); } } } } }
