Get Battery Charge Information Programmatically

问题

(Xcode 6, OSX 10.10.3) How do I get the battery charge information of a Mac (Charge Status, Battery level, Cycle count, Maximum charge in mAH) programmatically?

Hope this'll help you:

It uses non-approved calls, so don’t post your application with this code or you may be rejected!

From Apple; so don't worry about this code: https://developer.apple.com/library/ios/samplecode/BatteryStatus/Introduction/Intro.html (With complete sample code)

Use PFSystemKit. It is a framework that gives you about anything (besides sensors/smc info), including battery life, cycle, temperature and other stuff, just import the framework. Then add #import <PFSystemKit/PFSystemKit.h>. Then just add this code for battery info, make sure to change "cycleCount" to something else in a different case

 PFSystemKit *systemKit = [PFSystemKit investigate];
 NSString *batteryCycle = [systemKit.batteryReport cycleCount];
 [label setStringValue:batteryCycle];

PS, sorry for a late response :P, and just a heads up I have a macmini so my output is NULL!
