iOS獲取健康的運(yùn)動(dòng)步數(shù)恼琼，需要注意篩選下用戶手動(dòng)編輯錄入的數(shù)據(jù)唠摹，HKMetadataKeyWasUserEntered 為1時(shí)魂务，為手動(dòng)錄入數(shù)據(jù)集币。

1. 獲取健康運(yùn)動(dòng)數(shù)據(jù)前，需要在該key下添加HealhtKit功能
   

   identifier添加HealthKit功能

2. 在項(xiàng)目info.plist里添加授權(quán)描述翠忠，目前只用到了獲取步數(shù)的權(quán)限鞠苟。
   

   獲取健康數(shù)據(jù)授權(quán)描述

3. 開始引入#import <HealthKit/HealthKit.h> 獲取步數(shù)問(wèn)題。

#import <HealthKit/HealthKit.h>
