目前不知道怎么实现动态加载，可以换种思路来做做

1、制作头像的atlas

2、新建一个PlayerPanel(UIPanel)，Depth设置为2(具体根据图层设置)，PlayerPanel下新建三个组件username(UILable)、avatar(UISprite)、account(UILable)

3、将PlayerPanel拖入Resources文件夹，制作成prefab

4、场景UI Root->Camera->Anchor->Panel绑定脚本xxx, 脚本定义变量，将PlayerPanel预制绑定

5、Start ()编辑脚本：

GameObject go = NGUITools.AddChild(this.gameObject, _hero);  go.name = "动态";  go.transform.localPosition = new Vector3(go.transform.localPosition.x, 0, go.transform.localPosition.z);  UISprite avatar = go.GetComponentInChildren
     
       ();avatar.spriteName = "2";UILabel[] _lable = go.GetComponentsInChildren
      
        ();_lable [0].text = "100";
      
     

 

6、如果要销毁对象: Destroy(go);
