Mac OS X的鼠标按钮和按键计数器

有用于Linux和Windows的技术，但是在Mac OS X中有没有一种方法可以计算鼠标和键盘事件？我有兴趣对自己的日常活动进行统计分析。

基于MrDaniel提供的灵感，我决定编写一个简单的小柜台。

源代码减去定义为的UI xib；使用Foundation和AppKit框架（GitHub上的完整源代码和Xcode项目）：

WhatPulse可在Windows，OS X和Linux上运行。

感谢Vsauce指出了这一点。

Typingstats显示击键总数和各种其他指标。它不计算指向设备的点击次数。

通过编写可接收并计算鼠标和键盘点击事件的Cocoa Objective-C程序，可以实现点击和按下按钮的计数器程序。

要看的类是NSEvent，特别是addGlobalMonitorForEventsMatchingMask：handler：类方法应该被证明是非常有用的。由于它提供监视事件，例如：

NSLeftMouseUp

NSRightMouseUp

NSOtherMouseUp

NSLeftMouseDown

NSRightMouseDown

NSOtherMouseDown

NSKeyDown
