Unity 事件2

UIMouseEvent.cs:

using UnityEngine;
using System;

public abstract class UIMouseEvent : MonoBehaviour
{
	public EventHandler<EventArgs> MouseEvent { get; set; }
}

 

UIEvent.cs:

using UnityEngine;
using System;
using System.Collections.Generic;
using System.Collections;

public class UIEvent
{
	public static GameObject FindChild (string objName)
	{
		GameObject obj = GameObject.Find("quickLoginBtn");
		return obj;
	}

	public static void AddChildMouseClickEvent (string objName, EventHandler<EventArgs> action)
	{
		AddMouseClickEvent (FindChild (objName), action);
	}
	
	public static void AddMouseClickEvent (GameObject obj, EventHandler<EventArgs> action)
	{
		if (obj != null) {
			AddEvent<UIMouseClick> (obj, action);
		}		
		Debug.Log("111111");
	}

	public static void AddEvent<T> (GameObject obj, EventHandler<EventArgs> action) where T : UIMouseEvent
	{
		T mouseEvent = obj.GetComponent<T> ();
		if (null != mouseEvent) {
			GameObject.DestroyImmediate (mouseEvent);
		}
		mouseEvent = obj.AddComponent<T> ();
		mouseEvent.MouseEvent = action;		
		Debug.Log("22222");
	}
	
	public static void AttachEvent ()
	{
		Debug.Log ("AttachEvent");
		AddChildMouseClickEvent ("quickLoginBtn", OnClickStart);
	}

	private static void OnClickStart (object sender, EventArgs e)
	{
		Debug.Log("OnClickStart");
	}
}

 

UIMouseClick.cs:

using UnityEngine;
using System;

public class UIMouseClick : UIMouseEvent
{
	void OnClick()
	{		
		Debug.Log("hhhhh");	
		UIEvent.AttachEvent();
		if(null != MouseEvent)
		MouseEvent(gameObject, null);
	}
}

 

最后把UIMouseClick.cs放到NGUI的button上面就可以了，这个button的名字为“quickLoginBtn”，结果如下：
