NGUI 为带UIButton组件的GO添加带参数的事件侦听

private void addEventListener(GameObject button)
{
    EventDelegate eventDelegate = new EventDelegate(this, "OnChildClick");
    eventDelegate.parameters[0] = new EventDelegate.Parameter();
    eventDelegate.parameters[0].obj = button;
    EventDelegate.Add(button.GetComponent<UIButton>().onClick, eventDelegate);
}
