iOS - LumberjackLauncher 使用 前台直接

看了网上相关的介绍比较少，个人感觉它比较实用，写一下用法。

==本人已经将其封装，github地址 直接pod GQLogger 也可以放心食用 😊
博文地址 https://linit.space/ios-lumberjacklauncher-shi-yong/ ==

主要功能

1. 结合ddlog也就是CocoaLumberjack使用，能将打印的日志显示到一个View上，便于开发排查问题，直接显示网络包等。
2. 方便查看打印的Log

用法

1. 头文件
   #import "LumberjackLauncher.h"
2. 初始化
   [LumberjackLauncher launchStandardLoggers];
3. 配置

    [LumberjackLauncher setXcodeConsoleLogColorsWithErrorColor:self.setting.errorColor
                                                  warningColor:self.setting.warningColor
                                                     infoColor:self.setting.infoColor
                                                    debugColor:self.setting.debugColor                                                  verboseColor:self.setting.verboseColor];

4. 使用

 [LumberjackLauncher showAppConsole];
 [LumberjackLauncher hideAppConsole];
