Smart tips

If you need an intelligent reminder from your editor (PhpStorm etc.) to use 'Yii::$app->wechat', add the following to 'Yii \ Base \Application' :

<?php

namespace yii\base;

use Yii;

/**
 *
 * @property \yiiframe\easywechat\Wechat $wechat Add this line to make the editor smart prompt.
 *
 * @author Qiang Xue <qiang.xue@gmail.com>
 * @since 2.0
 */
abstract class Application extends Module
{

}
