为毛要实现这个工具?
在我小时候,每当游戏在真机运行时,我们看到的日志是这样的。
没高亮啊,还有乱七八糟的堆栈信息,好干扰日志查看,好影响心情。还有就是必须始终连着usb线啊，我想要想躺着测试。。。
以上种种原因,QConsole诞生了。
如何使用?
使用方式和QLog一样,在初始化出调用,简单的一句。
QConsole.Instance(); 就好了,使用之后效果是这样的。
在Editor模式下,F1控制开关。 在真机上需要在屏幕上同时按下五个手指就可以控制开关了。(本来考虑11个手指萌一下的)。
实现思路:
1.首先要想办法获取Log,这个和上一篇介绍的QLog一样,需要使用Application.logMessageReceived这个api。
2.获取到的Log信息要存在一个Queue或者List中,然后把Log输出到屏幕上就ok了。
3.输出到屏幕上使用的是OnGUI回调和 GUILayout.Window这个api, 总共三步。
贴上代码:

```注意事项:
和上一篇介绍的QLog一样,需要依赖上上篇文章介绍的QApp。
QConsole初步实现来自于开源Unity插件Unity-WWW-Wrapper中的Console.cs.在此基础上添加了ScrollToBottom选项。因为这个插件的控制台不支持滚动显示Log,需要拖拽右边的scrollBar,很不方便。
Unity-WWW-wrapper非常不稳定,建议大家不要使用。倒是感兴趣的同学可以研究下实现,贴上地址:
