Question

我需要在点击按钮时尝试获取按钮名称。我做了一个示例，但没有使用arg值，但它没有arg值成功。我是UNITY3D的新手。所以请看下面的代码并建议我该怎么做？

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.
System.MonoType.InvokeMember (System.String name, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object target, System.Object[] args, System.Reflection.ParameterModifier[] modifiers, System.Globalization.CultureInfo culture, System.String[] namedParameters) (at /Users/builduser/buildslave/monoAndRuntimeClassLibs/build/mcs/class/corlib/System/MonoType.cs:520)

错误消息表示Unity / NGUI尝试调用的方法的签名没有参数。

你是如何告诉NGUI在点击按钮时调用该方法的？

自从我使用NGUI以来已经有很长一段时间了，但似乎获取点击事件的方法是在按钮上有一个脚本OnClick（）。根据该按钮上的脚本的性质，您可以访问被单击的按钮（this.gameObject.name）。此外，根据这些docs，您可以使用UICamera.currentTouchID来获取所单击按钮的ID。

NGUI按钮单击UNITY3D中的事件问题？
