代码添加UI的EventTrigger点击事件

代码如下：

第一种情况

/// <summary>
/// 点击
/// </summary>
/// <param name="action"></param>
/// <param name="MyObject"></param>
public static void PointerClickEvent(Action action, GameObject MyObject)
{
    // 定义所要绑定的事件类型
    EventTrigger.Entry entry = new EventTrigger.Entry();
    // 设置事件类型
    entry.eventID = EventTriggerType.PointerClick;
    // 初始化回调函数
    entry.callback = new EventTrigger.TriggerEvent();
    // 定义回调函数
    UnityEngine.Events.UnityAction<BaseEventData> callBack = new UnityEngine.Events.UnityAction<BaseEventData>(((BaseEventData baseEventData) => {
        action();
    }));
    // 绑定回调函数
    entry.callback.AddListener(callBack);
    //添加事件组件，添加方法
    MyObject.AddComponent<EventTrigger>().triggers.Add(entry);
}

第二种情况

/// <summary>
       /// 开始拖拽并获取位置
       /// </summary>
       /// <param name="action"></param>
       /// <param name="MyObject"></param>
       public static void DragEvent(Action<PointerEventData> action, GameObject MyObject)
       {
           // 定义所要绑定的事件类型
           EventTrigger.Entry entry = new EventTrigger.Entry();
           // 设置事件类型
           entry.eventID = EventTriggerType.Drag;
           // 初始化回调函数
           entry.callback = new EventTrigger.TriggerEvent();
           // 绑定回调函数
           entry.callback.AddListener((baseEventData) =>action(baseEventData as PointerEventData));
           //添加事件组件，添加方法
           MyObject.AddComponent<EventTrigger>().triggers.Add(entry);
       }
