导入NGUI包

创建MainCameraScript.cs脚本
MainCameraScript.cs

using UnityEngine;
using System.Collections;

public class MainCameraScript : MonoBehaviour {

    // Use this for initialization
    void Start () {
    
    }
    
    // Update is called once per frame
    void Update () {
    
    }
}

创建NGUI根节点的方法

    private GameObject Window{ set; get;}

    void CreateUI()
    {
        //创建根节点
        this.Window = NGUITools.CreateUI(false).gameObject;
    }

在Window上添加滚动子视图

    void CreateUI()
    {
        //创建根节点
        this.Window = NGUITools.CreateUI(false).gameObject;

        //在根节点上创建一个UIScrollView子控件
        UIScrollView scrollView = NGUITools.AddChild(this.Window);

    }

在滚动视图上添加Grid表格调整布局

    void CreateUI()
    {
        //创建根节点
        this.Window = NGUITools.CreateUI(false).gameObject;

        //在根节点上创建一个UIScrollView子控件
        UIScrollView scrollView = NGUITools.AddChild(this.Window);

        //在滚动视图上添加UIGrid子控件,来调整布局
        UIGrid  grid = NGUITools.AddChild(scrollView.gameObject);

        //设置grid表格的布局方向
        grid.arrangement = UIGrid.Arrangement.Horizontal;
        grid.cellWidth = 100.0f;
        grid.cellHeight = 100.0f;
        grid.animateSmoothly = false;
    }

添加创建Label的方法

    /// 

    /// 创建一个小Label控件
    /// 
    /// The label item.
    UILabel CreateLabelItem(string name,GameObject parent)
    {
        //创建一个Lalel控件
        UILabel label = NGUITools.AddChild (parent);

        //修改Label的字体及颜色
        Font f = (Font)Resources.Load ("Arial", typeof(Font));
        label.bitmapFont = NGUITools.AddMissingComponent(label.gameObject);
        label.bitmapFont.dynamicFont = f;
        label.color = Color.red;

        //设置Label要显示的文字
        label.text = name;

        //添加滚动ScrollView时要用到的碰撞器和脚本
        label.autoResizeBoxCollider = true;
        NGUITools.AddMissingComponent (label.gameObject);
        NGUITools.AddMissingComponent (label.gameObject);

        //重新调整碰撞器的大小
        label.ResizeCollider ();
        
        return label;
    }

在Grid上添加10个Label控件

    void CreateUI()
    {
        //创建根节点
        this.Window = NGUITools.CreateUI(false).gameObject;

        //在根节点上创建一个UIScrollView子控件
        UIScrollView scrollView = NGUITools.AddChild(this.Window);

        //在滚动视图上添加UIGrid子控件,来调整布局
        UIGrid  grid = NGUITools.AddChild(scrollView.gameObject);

        //设置grid表格的布局方向
        grid.arrangement = UIGrid.Arrangement.Horizontal;
        grid.cellWidth = 100.0f;
        grid.cellHeight = 100.0f;
        grid.animateSmoothly = false;

        //在Grid表格上添加20个Label对象
        for (int i = 0; i < 10; i++) 
        {
            CreateLabelItem (Random.Range (100, 999).ToString(), grid.gameObject);
        }

        //重新排版
        grid.Reposition ();
    }

整个MainCameraScript.cs的代码如下

using UnityEngine;
using System.Collections;

public class MainCameraScript : MonoBehaviour {


    private GameObject Window{ set; get;}

    void CreateUI()
    {
        //创建根节点
        this.Window = NGUITools.CreateUI(false).gameObject;

        //在根节点上创建一个UIScrollView子控件
        UIScrollView scrollView = NGUITools.AddChild(this.Window);

        //在滚动视图上添加UIGrid子控件,来调整布局
        UIGrid  grid = NGUITools.AddChild(scrollView.gameObject);

        //设置grid表格的布局方向
        grid.arrangement = UIGrid.Arrangement.Horizontal;
        grid.cellWidth = 100.0f;
        grid.cellHeight = 100.0f;
        grid.animateSmoothly = false;

        //在Grid表格上添加20个Label对象
        for (int i = 0; i < 10; i++) 
        {
            CreateLabelItem (Random.Range (100, 999).ToString(), grid.gameObject);
        }

        //重新排版
        grid.Reposition ();
    }

    /// 

    /// 创建一个小Label控件
    /// 
    /// The label item.
    UILabel CreateLabelItem(string name,GameObject parent)
    {
        //创建一个Lalel控件
        UILabel label = NGUITools.AddChild (parent);

        //修改Label的字体及颜色
        Font f = (Font)Resources.Load ("Arial", typeof(Font));
        label.bitmapFont = NGUITools.AddMissingComponent(label.gameObject);
        label.bitmapFont.dynamicFont = f;
        label.color = Color.red;

        //设置Label要显示的文字
        label.text = name;

        //添加滚动ScrollView时要用到的碰撞器和脚本
        label.autoResizeBoxCollider = true;
        NGUITools.AddMissingComponent (label.gameObject);
        NGUITools.AddMissingComponent (label.gameObject);

        //重新调整碰撞器的大小
        label.ResizeCollider ();
        
        return label;
    }

    // Use this for initialization
    void Start () {

        CreateUI ();
    }
    
    // Update is called once per frame
    void Update () {
    
    }
}

效果如下
