为了方便用户进行语言切换，所以在调用英文版之前，只需要在进入直播/短视频界面之前调用方法，则会展示英文版。如果手机系统语言是英文版，则不需要调用该方法 （To facilitate user language switching, the English version is only required before calling the English version before calling the method before entering the live / short video interface. If the mobile phone system language is English, you do not need to call this method） ``` [[RookieTools shareInstance] resetLanguage:kLanguage_EN withFrom:@""]; ```
