iOS 调用百度翻译 API 将中文 strings 翻译成其他国家语言

translation.py

# /usr/bin/env python
# -*- coding: utf-8 -*-

# 同级目录下面包含 Localizable.strings 或者 InfoPlist.strings，把strings文件的注释都去掉
# cnFile 参数修改需要翻译Localizable还是InfoPlist
# 到百度翻译API页面申请免费的appid和secretKey(http://api.fanyi.baidu.com/api/trans/product/index)
# 百度翻译每月翻译字符数低于200万，享免费服务
# 会自动生成对应的.lproj目录
