iOS利用HealthKit框架從健康app中獲取步數(shù)信息題文章

/**

  • @title: iOS利用HealthKit框架從健康app中獲取步數(shù)信息
  • 1.第一步首先需要開啟HealthKit
  • TARGETS -> Capabilities -> HealthKit -> YES
  • 在此目錄欄下，有一個steps，會顯示一個?
  • eg：add the "HealthKit" entitlement to your app id
  • 這是 你可能需要Fix issue ，這時候可能會在項目中出現(xiàn).entitlements 文件
  • 相關(guān)處理請自行查資料直到ok為止
  • 2.新建一個HealthKitManage類，繼承于NSObject
  • (1)導(dǎo)入頭文件

  • import <HealthKit/HealthKit.h>

  • import <UIKit/UIKit.h>

  • define HKVersion [[[UIDevice currentDevice] systemVersion] doubleValue]

  • define CustomHealthErrorDomain @"com.sdqt.healthError

  • 相關(guān)的方法請自行查看 HealthKitManage.h & HealthKitManage.m 文件（已封裝）
  • 3.相關(guān)的調(diào)用
  • HealthKitManage *manage = [HealthKitManage shareInstance];
  • 然后調(diào)用相關(guān)的方法（對象 ＋ 方法名）
  • 4.參考博客：http://www.itdecent.cn/p/1dd6ad5b1520
