十,iOS 健康數據獲取權限和寫入權限

分類:編程 時間:2017-02-18

1,Xcode 8之後需要在info.plist 中設置以下兩個權限;

  (1)Privacy - Health update Usage Description

 (2)Privacy - Health Share Usage Description

2,導入頭文件;

#import <HealthKit/HealthKit.h>
#import <UIKit/UIDevice.h>

3,設置讀取數據的權限和寫入數據的權限

#pragma mark - 設置寫入權限
- (NSSet *)dataTypesToWrite {
    HKQuantityType *stepType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];
    HKQuantityType *distanceType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];
    return [NSSet setWithObjects:stepType,distanceType, nil];
}

#pragma mark - 設置讀取權限
- (NSSet *)dataTypesToRead {

以下為設置的權限類型:

   HKQuantityType *stepType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];
    HKQuantityType *distanceType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];

    return [NSSet setWithObjects:stepType,distanceType, nil];
}

以下是關於fitness的全部權限介紹可以直接去看HKQuantityType.h文件很詳細,有//fitness,// Body Measurements,// Results,// Vitals等

// Fitness
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierStepCount HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);                 // Scalar(Count),               Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierDistanceWalkingRunning HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);    // Length,                      Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierDistanceCycling HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);           // Length,                      Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierDistanceWheelchair HK_AVAILABLE_IOS_WATCHOS(10_0, 3_0);       // Length,               Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierBasalEnergyBurned HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);         // Energy,                      Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierActiveEnergyBurned HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);        // Energy,                      Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierFlightsClimbed HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);            // Scalar(Count),               Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierNikeFuel HK_AVAILABLE_IOS_WATCHOS(8_0, 2_0);                  // Scalar(Count),               Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierAppleExerciseTime HK_AVAILABLE_IOS_WATCHOS(9_3, 2_2);         // Time                         Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierPushCount HK_AVAILABLE_IOS_WATCHOS(10_0, 3_0);                // Scalar(Count),               Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierDistanceSwimming HK_AVAILABLE_IOS_WATCHOS(10_0, 3_0);         // Length,                      Cumulative
HK_EXTERN HKQuantityTypeIdentifier const HKQuantityTypeIdentifierSwimmingStrokeCount HK_AVAILABLE_IOS_WATCHOS(10_0, 3_0);      // Scalar(Count),               Cumulative


4,判斷設備是否支持

 if(![HKHealthStore isHealthDataAvailable]){
        NSLog(@"設備不支持healthkit");
    }

5,獲取權限和獲取數據

 //    此處獲取權限的寫入和讀取 獲取之後才可以加到數據中
    NSSet *writeDataTypes = [self dataTypesToWrite];
    NSSet *readDataTypes = [self dataTypesToRead];
    [self.healthstore requestAuthorizationToShareTypes:writeDataTypes readTypes:readDataTypes completion:^(BOOL success, NSError * _Nullable error) {
        if (success) {
 
            [self getStepsFromHealthKit];//第二種獲取方法
//            [self getdistanceFromHealthKit]; //獲取公裏數
        }else{
       
        }
    }];
    
6,獲取具體的數據的方法,三個方法是一起的//unit此處需要註意的是單位的不同

- (void)getDistancesFromHealthKit{
    HKQuantityType *stepType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];
    [self fetchSumOfSamplesTodayForType:stepType unit:[HKUnit meterUnit] completion:^(double stepCount, NSError *error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"你的公裏數為:%.f",stepCount);
            self.pedoLab.text = [NSString stringWithFormat:@"%.2fm",stepCount];
        });
    }];
}

#pragma mark - 讀取HealthKit數據
- (void)fetchSumOfSamplesTodayForType:(HKQuantityType *)quantityType unit:(HKUnit *)unit completion:(void (^)(double, NSError *))completionHandler {
    NSPredicate *predicate = [self predicateForSamplesToday];
    
    HKStatisticsQuery *query = [[HKStatisticsQuery alloc] initWithQuantityType:quantityType quantitySamplePredicate:predicate options:HKStatisticsOptionCumulativeSum completionHandler:^(HKStatisticsQuery *query, HKStatistics *result, NSError *error) {
        HKQuantity *sum = [result sumQuantity];
        NSLog(@"result ==== %@",result);
        if (completionHandler) {
            double value = http://www.ithao123.cn/[sum doubleValueForUnit:unit];
             NSLog(@"sum ==== %@",sum);
            NSLog(@"value =http://www.ithao123.cn/==%f",value);

            completionHandler(value, error);
        }
    }];
    [self.healthstore executeQuery:query];
}

#pragma mark - NSPredicate數據模型
- (NSPredicate *)predicateForSamplesToday {
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDate *now = [NSDate date];
    NSDate *startDate = [calendar startOfDayForDate:now];
    NSDate *endDate = [calendar dateByAddingUnit:NSCalendarUnitDay value:1 toDate:startDate options:0];
    return [HKQuery predicateForSamplesWithStartDate:startDate endDate:endDate options:HKQueryOptionStrictStartDate];
}

7,添加和寫入數據,並重新獲取數據

#pragma mark - 添加步數
- (void)adddistanceWithStepNum:(double)stepNum {
    HKQuantitySample *stepCorrelationItem = [self distanceCorrelationWithStepNum:stepNum];
    
    [self.healthstore saveObject:stepCorrelationItem withCompletion:^(BOOL success, NSError *error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (success) {
                [self.view endEditing:YES];
                UIAlertView *doneAlertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"添加成功" delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil, nil];
                [doneAlertView show];
                //刷新數據  重新獲取距離
                [self getDistancesFromHealthKit];
                
            }else {
                NSLog(@"The error was: %@.", error);
                UIAlertView *doneAlertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"添加失敗" delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil, nil];
                [doneAlertView show];
                return ;
            }
        });
    }];
}

- (HKQuantitySample *)distanceCorrelationWithStepNum:(double)stepNum {
    NSDate *endDate = [NSDate date];
    NSDate *startDate = [NSDate dateWithTimeInterval:-300 sinceDate:endDate];
  /** 

//這裏的quantityWithUnit單位如果不對則會報錯註意 ,有以下單位獲取下面的對應的健康數據需要註意

+ (instancetype)meterUnitWithMetricPrefix:(HKMetricPrefix)prefix;      // m
+ (instancetype)meterUnit;  // m
+ (instancetype)inchUnit;   // in
+ (instancetype)footUnit;   // ft
+ (instancetype)yardUnit HK_AVAILABLE_IOS_WATCHOS(9_0, 2_0);   // yd
+ (instancetype)mileUnit;   // mi

**/
    HKQuantity *stepQuantityConsumed = [HKQuantity quantityWithUnit:[HKUnit meterUnit] doubleValue:stepNum];
    HKQuantityType *stepConsumedType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];
    
    NSString *strName = [[UIDevice currentDevice] name];
    NSString *strModel = [[UIDevice currentDevice] model];
    NSString *strSysversion = [[UIDevice currentDevice] systemVersion];
    NSString *localeIdentifier = [[NSLocale currentLocale] localeIdentifier];
    
    HKDevice *device = [[HKDevice alloc] initWithName:strName manufacturer:@"Apple" model:strModel hardwareVersion:strModel firmwareVersion:strModel softwareVersion:strSysVersion localIdentifier:localeIdentifier UDIDeviceIdentifier:localeIdentifier];
    
    HKQuantitySample *stepConsumedSample = [HKQuantitySample quantitySampleWithType:stepConsumedType quantity:stepQuantityConsumed startDate:startDate endDate:endDate device:device metadata:nil];
    
    return stepConsumedSample;
}
