/** 前段时间iOS 健康数据非常的火，我忍不住寂寞，写了一个博客：
* @title: iOS利用HealthKit框架从健康app中获取步数信息
*
* 1.第一步首先需要开启HealthKit
* TARGETS -> Capabilities -> HealthKit -> YES
*
* 在此目录栏下，有一个steps，会显示一个❌(图片如下：health.png)
* eg：add the "HealthKit" entitlement to your app id
* 这是 你可能需要Fix issue ，这时候可能会在项目中出现.entitlements文件
* 相关处理请自行查资料直到ok为止
*
* 2.新建一个HealthKitManage类，继承于NSObject
* (1)导入头文件
* #import <HealthKit/HealthKit.h>
* #import <UIKit/UIKit.h>
* #define HKVersion [[[UIDevice currentDevice] systemVersion] doubleValue]
* #define CustomHealthErrorDomain @"com.sdqt.healthError
* 相关的方法请自行查看 HealthKitManage.h & HealthKitManage.m 文件（已封装）
*
* 3.相关的调用
* HealthKitManage *manage = [HealthKitManage shareInstance];
* 然后调用相关的方法（对象＋ 方法名）
*
* 4.参考博客：http://www.jianshu.com/p/1dd6ad5b1520
