NGUI在UNITY3D中单击事件问题？

Question

每当点击按钮时，我都需要尝试获取按钮名。我做了一个示例，但是没有arg值就不能工作，但是没有arg值，它可以成功地工作。我是UNITY3D.So新手，请看下面的代码，并建议我怎么做？

代码：

using UnityEngine;
using System.Collections;

public class IG : MonoBehaviour 
{

    // Use this for initialization
    void Start () 
    {
        Debug.Log (" **** Start() **** ");
    }

    // Update is called once per frame
    void Update () 
    {

    }

    //TODO :: Button Click event
    public void IGBtn(string BtnName)
    {
        Debug.Log (" **** IGBtn Clicked **** "+BtnName);
    }
}

错误是：

MissingMethodException: The best match for method IGBtn has some invalid parameter.

错误消息意味着Unity试图调用的方法的签名没有参数。

你是如何让NGUI在点击按钮时调用该方法的？

自从我使用NGUI以来已经有很长时间了，但是获得单击事件捕获的方法似乎是在按钮上有一个带有OnClick()方法的脚本。根据脚本在该按钮上的性质，您可以访问单击的按钮(this.gameObject.name)。此外，根据这些文档，您可以使用UICamera.currentTouchID获取单击按钮的id。
