需求：
1.最近需要在APP當中增加記步功能碳想，提升用戶的活躍率。并且希望能夠保留用戶的健康數(shù)據(jù)川陆。
2.根據(jù)蘋果健康的數(shù)據(jù)剂习，查詢用戶最近今天的步行和運動距離。
3.用戶在頁面當中開始記步较沪，記錄用戶的步行數(shù)據(jù)鳞绕，存入本地數(shù)據(jù)庫。
前期：
1.查看計步器開發(fā)尸曼，常用的技術(shù)们何。了解到iOS當中，針對用戶運動健康數(shù)據(jù)以及計步器功能主要涉及兩個框架HealthKit控轿，CoreMotion（最低支持到iOS8.0,硬件5S及以上）冤竹。
參考：http://www.reibang.com/p/1dd6ad5b1520 （包括在應用中打開HealthKit,Info.plist增加權(quán)限）
有一點需要特別注意：當打開HealthKit過后，會在info.plist的字段Required device capabilities 當中增加healthkit茬射，這個字段的存在會在打包上傳到itunes connect的時候報錯鹦蠕，信息如下：
ERROR ITMS-90098: "This bundle is invalid. The key UIRequiredDeviceCapabilities contains value 'healthkit' which is incompatible with the MinimumOSVersion value of '7.0'."
WARNING ITMS-90109: "This bundle is invalid. The key UIRequiredDeviceCapabilities in the Info.plist may not contain values that would prevent this application from running on devices that were supported by previous versions. Refer to QA1623 for additional information: https://developer.apple.com/library/ios/#qa/qa1623/_index.html"
因為我們線上的APP 版本包含7.0系統(tǒng)以及IPAD的支持，參考stack overflow的解答躲株，刪除info.plist當中的字段即可重新打包上傳片部。
2.查閱APPLE官方文檔關于HealthKit,CoreMotion的說明。
https://developer.apple.com/documentation/healthkit (官方HealthKit說明)
https://developer.apple.com/documentation/coremotion(官方CoreMotion說明)
3.看如下的代碼處理過程（有什么使用不當?shù)臍g迎指出）：
（1）框架導入：
#import <CoreMotion/CMPedometer.h>
#import <HealthKit/HealthKit.h>
（2）添加記步管理分類
@interface KKPedometerManager : NSObject
+ (instancetype)sharedManager;
//查詢Health kit 計步數(shù)據(jù)
- (BOOL)checkHealthKitStepCountDataWithDate:(NSDate *)date Completion:(void(^)(NSString *result,NSString *timeValue))completion;
//查詢Health kit 跑步+走路里程
- (BOOL)checkHealthKitMilesDataCompletion:(void(^)(NSString *result,NSString *timeValue))completion;
//計步器查詢當天的計步數(shù)據(jù)
- (void)quereSportsDataforTodayCompltion:(void(^)(NSString *stepCount,NSString *milesCount,NSError *error))completion;
//開始計步器計步
- (void)startPedometerCountWithModelData:(KKSportsModel *)model Compltion:(void(^)(NSString *stepCount,NSString *milesCount))completion;
//停止計步
- (void)stopPedomertCount;
@end

其他：審核注意事項
審核出現(xiàn)了以下的被拒問題：
Guideline 4.2.1 - Design - Minimum Functionality
Your app uses the HealthKit or CareKit APIs but does not indicate integration with the Health app in your app description and clearly identify the HealthKit and CareKit functionality in your app's user interface.
Next Steps
To resolve this issue, please revise your app description to specify that your app integrates with the Health app.
查閱審核開發(fā)文檔：
https://developer.apple.com/app-store/review/guidelines/#developer-information
然后APP信息描述當中加入了以下說明：
溫馨提示：
-XXXX已接入HealthKit,可同步數(shù)據(jù)到【健康】望浩。
-持續(xù)使用跑步GPS在后臺會影響電池續(xù)航時間辖所。
Note:
Continued use of GPS running in the background can dramatically decrease battery life.
