NITY按钮单击事件是否在UNITY3D中发布？

Question

I need to try to get button name whenever clicks on button.I did a sample but doesn't work with arg value but it works successfully without arg value.I am new to UNITY3D.So please see the below code and suggest me what to do?

Code :

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);
    }
}

Error is :

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

The error message means that the signature for the method Unity/NGUI is trying to invoke has no parameters.

How did you tell NGUI to call that method on button click?

It's been a long while since I've used NGUI, but it seems like the way to get a capture a click event is to have a script on the button that has a method OnClick(). By nature of the script being on that button you have access to the button that was clicked (this.gameObject.name). Also, according to these docs you can use UICamera.currentTouchID to get the id of the button that was clicked.
