YII实现分页的方法

public function actionTest() 
{ 
$criteria=new CDbCriteria; 
$criteria->order='id DESC'; 
$count=User::model()->count($criteria); 
$pager=new CPagination($count); 
$pager->pageSize=10; 
$pager->applyLimit($criteria); 
$userList=User::model()->findAll($criteria); 
$this->render('test',array('list'=>$userList,'pages'=>$pager)); 
} 

<?php 
foreach($list as $o) 
{ 
echo $o->username.'<br/>'; 
echo $o->id.'<br/>'; 
} 
$this->widget('CLinkPager',array( 
'header'=>'', 
'firstPageLabel' => '首页', 
'lastPageLabel' => '末页', 
'prevPageLabel' => '上一页', 
'nextPageLabel' => '下一页', 
'pages' => $pages, 
'maxButtonCount'=>13 
) 
); 
?>
