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

How to use

CocoaPods (recommended)

pod 'ZHLog'

Getting Started

import <ZHLog/ZHShareLog.h>

Example Usage

ZHLog(@"zhlog"); //仅打印消息
ZHLogDebug(@"debug"); //打印消息并附带函数名，所在行等调试信息。
ZHLogInfo(@"Info");//打印分类消息并附带函数名，所在行等调试信息。下面类似不一一介绍了。
ZHLogImportant(@"Important");//Print important information, along with the name of the function, the line and so on.
ZHLogError(@"error");//Print the error message, along with the name of the function, the line, and so on.
ZHLogWarning(@"warning");//Print the warning message, along with the name of the function, the line, and so on.
ZHLogToFile(@"tofile", ZH_Log_Info);//Print the information, attach the name of the function, the line, and so on, and save it to the log.

[[ZHShareLog shareZHShareLog]printDebugInfo:@"Info" withLevel:ZH_Log_Error];//Print different types of information.

Log type

typedef NS_ENUM(NSInteger,ZH_Log_Level)
{
    ZH_Log_Error = 0,
    ZH_Log_Info = 1,
    ZH_Log_Warning = 2,
    ZH_Log_Debug = 3,
    ZH_Log_Important = 4,
    ZH_Log_Verblose = 5,
};

Clear the log

-(void)clearAllLogFile;
-(void)clearMonthAgoLogFile;
-(void)clearTodayLog;

Print binary stream data.

-(void)printLogWithBuffer:(Byte *)buffer andLength:(NSUInteger)length andLabel:(NSString *)flagStr;

Xcode terminal prints the screenshot

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。
