yii2的分页组件

public function actionIndex(){
$db = new Query;
$count = $db->select('notice_id')->from('notice')->count(); // 查询需要分页的目的数据的总个数
$newspagination = new \yii\data\Pagination(['totalCount'=>$count,'defaultPageSize' => 2]);
$data = News::find()->orderBy('release_time DESC')->offset($newspagination->offset)->limit($newspagination->limit)->all();
return $this->render('index',['data'=>$data,'newspagination'=>$newspagination]);
}

<?php
echo \yii\widgets\LinkPager::widget([
'pagination'=>$newspagination,//分页类
'options'=>['class'=>'page'],  //设置分页组件样式
]);
?>
