1、创建behavior

// frontend/behaviors/MobileBehavior.phpclass MobileBehavior extends \yii\base\Behavior{ public function events() { return [ \yii\web\Controller::EVENT_BEFORE_ACTION => 'beforeAction' ]; } public function beforeAction($event) { if (strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') { $event->sender->module->setViewPath($event->sender->module->getBasePath().DIRECTORY_SEPARATOR.'H5Views'); } }}

2、建一个基类BaseController.php

// frontend/controllers/BaseController.phpclass BaseController extends \yii\web\Controller{ public function behaviors() { return [ \frontend\behaviors\MobileBehavior::className() ]; } // 其他action}

其他控制器继承BaseController。
3、在frontend下面创建H5Views, H5模板文件放在这里面就OK了。
