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<UIScrollView>
(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<UIScrollView>
(this.Window); //在滚动视图上添加UIGrid子控件,来调整布局 UIGrid grid = NGUITools.AddChild<UIGrid>
(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<UIScrollView>
(this.Window); //在滚动视图上添加UIGrid子控件,来调整布局 UIGrid grid = NGUITools.AddChild<UIGrid>
(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
