Yii2-自适应切换模板

// frontend/behaviors/MobileBehavior.php

class MobileBehavior extends yiibaseBehavior
{
    public function events()
        {
            return [
                    yiiwebController::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.php
class BaseController extends yiiwebController
{
    public function behaviors()
        {
            return [
                    frontendbehaviorsMobileBehavior::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。
