iOS 获取步数等健康信息

导入HealthKit.framework

info.plist中添加权限配置

<!-- 健康分享 -->
<key>NSHealthShareUsageDescription</key>
<string>App需要您的同意,才能访问健康分享</string>

capabilities里面打开HealthKit

此外打包证书也需要勾选苹果健康选项

引入#import<HealthKit/HealthKit.h>

属性

{HKHealthStore  *store;
}@property (nonatomic, strong) NSMutableArray *healthSteps;//步数
@property (nonatomic, strong) NSMutableArray *healthCalories;//卡路里
@property (nonatomic, strong) NSMutableArray *healthDistances;//距离

在viewDidLoad里面进行初始化及苹果认证

self.healthSteps = [NSMutableArray array];self.healthDistances = [NSMutableArray array];self.healthCalories = [NSMutableArray array];NSSet *getData;// 1.判断设备是否支持HealthKit框架if ([HKHealthStore isHealthDataAvailable]) {getData = [self getData];} else {NSLog(@"---------不支持 HealthKit 框架");}store = [[HKHealthStore alloc] init];// 2.请求苹果健康的认证[store requestAuthorizationToShareTypes:nil readTypes:getData completion:^(BOOL success, NSError * _Nullable error) {if (!success) {NSLog(@"--------请求苹果健康认证失败");return ;}dispatch_async(dispatch_get_main_queue(), ^{// 3.获取苹果健康数据[self getHealthStepData];[self getHealthDistanceData];});}];

设置好要获取的数据类型

- (NSSet *)getData{HKQuantityType  *step = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];HKQuantityType *distance = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];return [NSSet setWithObjects:step,distance, nil];
}

- (void)updateDistance{NSCalendar *calendar = [NSCalendar currentCalendar];NSDate *now = [NSDate date];NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];NSDate *startDate = [calendar dateFromComponents:components];NSDate *endDate = [calendar dateByAddingUnit:NSCalendarUnitDay value:1 toDate:startDate options:0];HKQuantityType *sampleType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];NSPredicate *predicate = [HKQuery predicateForSamplesWithStartDate:startDate endDate:endDate options:HKQueryOptionStrictStartDate];HKStatisticsQuery *query = [[HKStatisticsQuery alloc] initWithQuantityType:sampleType quantitySamplePredicate:predicate options:HKStatisticsOptionCumulativeSum completionHandler:^(HKStatisticsQuery *query, HKStatistics *result, NSError *error) {//        if (!result) {//            if (completionHandler) {//                completionHandler(0.0f, error);//            }//            return;//        }double totalStep = [result.sumQuantity doubleValueForUnit:[HKUnit meterUnit]];NSLog(@" -------------距离统计是：%f",totalStep);}];[store executeQuery:query];
}

- (void)updateEnergy{NSCalendar *calendar = [NSCalendar currentCalendar];NSDate *now = [NSDate date];NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];NSDate *startDate = [calendar dateFromComponents:components];NSDate *endDate = [calendar dateByAddingUnit:NSCalendarUnitDay value:1 toDate:startDate options:0];HKQuantityType *sampleType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierDietaryEnergyConsumed];NSPredicate *predicate = [HKQuery predicateForSamplesWithStartDate:startDate endDate:endDate options:HKQueryOptionStrictStartDate];HKStatisticsQuery *query = [[HKStatisticsQuery alloc] initWithQuantityType:sampleType quantitySamplePredicate:predicate options:HKStatisticsOptionCumulativeSum completionHandler:^(HKStatisticsQuery *query, HKStatistics *result, NSError *error) {//        if (!result) {//            if (completionHandler) {//                completionHandler(0.0f, error);//            }//            return;//        }double totalStep = [result.sumQuantity doubleValueForUnit:[HKUnit calorieUnit]];NSLog(@" -------------卡路里统计是：%f",totalStep);}];[store executeQuery:query];
