U3d结合NGUI做的一个Tab切换例子
错误说明：以下例子，由于不熟悉NGUI各个控件：如:wiget / panel，所以用了panel，其实更应该用的是wiget !!!!!!!不然会增加Ｎ多个Panel次的渲染。
~~~
参考Unity3D 自定义选项卡组件结合以前的AS3写的一个
使用
public UIButton[] tabButtonList;//标签按钮
public GameObject[] contentList;//标签内容
TabGroup tabGroup = new TabGroup();
GameObject[] buttonList = new GameObject[tabButtonList.Length];
for (int i = 0; i < tabButtonList.Length; i++)
{
buttonList[i] = tabButtonList[i].gameObject;
}
tabGroup.AddTabs(buttonList);
tabGroup.OnTabGroup = delegate(int selectedIndex)
{
for (int j = 0; j < contentList.Length; j++)
{
bool selected = j == selectedIndex;
contentList[j].gameObject.SetActive(selected);//显示哪个内容
}
};
tabGroup.selectedIndex = 0;//默认第一个标签
