iOS利用HealthKit框架从健康app中获取步数信息

/** 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
