最近想利用空闲时间把自己在以往的工作中封装的一些工具，开源出来，供大家参考。这两天整理下了我的打印库ZHLog，已上传至Pods，欢迎大家下载使用。
ZHLog
ZHLog 是一个iOS打印工具库，方便，简单，快捷!
Features
- 支持仅在Debug模式打印输出。这也是这个库最开始写的原因之一！
- 支持打印类名，函数名，所在行，打印时间.
- 支持打印二进制流。蓝牙通讯中非常有用！
- 支持文件保存至本地，并通过ITunes导出！
- 支持打印信息分类，错误，警告等.
- 日志文件自动以日期命名，自动删除一个月以前日志.
- 支持手动删除日志文件.
- 欢迎二次开发。
Requirements
- iOS 7.0+
- ARC

ZH_Log_Warning = 2,
ZH_Log_Debug = 3,
ZH_Log_Important = 4,
ZH_Log_Verblose = 5,
};

Notice
如果需要导出日志文件，需要在工程info.plist列表中添加：Application supports iTunes file sharing 并设为 Yes! 如遇审核问你为何开通文件共享只需回复里面保存了日志文件，为了方便排查问题等等。
