*注意：需要iOS8以上，調用前判斷一下； 另外證書需要打開獲取健康數據功能，自己百度。
獲取健康數據，每天運動步數，實時獲取。*

其中HKHealthStore+AAPLExtensions 如下：

/*Copyright (C) 2014 Apple Inc. All Rights Reserved.See LICENSE.txt for this sample’s licensing informationAbstract:Contains shared helper methods on HKHealthStore that are specific to Fit's use cases.*/@import HealthKit;@interface HKHealthStore (AAPLExtensions)// Fetches the single most recent quantity of the specified type. - (void)aapl_mostRecentQuantitySampleOfType:(HKQuantityType *)quantityType predicate:(NSPredicate *)predicate completion:(void (^)(NSArray *results, NSError *error))completion;@end /*Copyright (C) 2014 Apple Inc.

這是哥哥我研究了幾天英文文檔才弄出來的（英文不好，痛苦死了），第一次寫博客，就貢獻了。

補充使用方法：

//倒入頭文件 #import "HealthManager.h"[[HealthManager shareInstance] getKilocalorieUnit:[HealthManager predicateForSamplesToday] quantityType:[HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierActiveEnergyBurned] completionHandler:^(double value, NSError *error) {if(error){DebugLog(@"error = %@",[error.userInfo objectForKey:NSLocalizedDescriptionKey]);}else{DebugLog(@"獲取到的卡路里 ＝ %.2lf",value);}}];[[HealthManager shareInstance] getRealTimeStepCountCompletionHandler:^(double value, NSError *error) {NSLog(@"當天行走步數 = %.2lf",value);}];

其中對錯誤處理不夠完善，項目剛開始，沒多少時間去看，自己解決哈。
