由于未捕获的异常'_HKObjectValidationFailureException'，应用程序终止。

我正在将血糖值保存到iOS的健康应用程序中。

-(void)viewDidLoad
{

    float bloodGlucose=20;   
    float bloodGlucoseValue= (int) bloodGlucose;   
    NSLog(@"Blood Glucose value is :%f",bloodGlucoseValue);   
    HKQuantityType *bloodGlucoseType=[HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierBloodGlucose];

    NSSet *requesObjects=[[NSSet alloc]initWithObjects:bloodGlucoseType, nil];   
    HKHealthStore  * hStore = [HKHealthStore new];

    [hStore requestAuthorizationToShareTypes: requesObjects readTypes:requesObjects completion:^(BOOL success, NSError *error) {

    //user response processing goes here, i.e.

    if(success) {          
    dispatch_async(dispatch_get_main_queue(), ^{

    [[GSHealthKitManager sharedManager]saveBloodGlucosePercentageintoHealthStore:bloodGlucoseValue];

    });

    }

    }];

}

-(void)saveBloodGlucosePercentageintoHealthStore:(float)bloodGlucoseValue
{

HKUnit *inches=[HKUnit gramUnit];
HKQuantity * glucoseQuantity = [HKQuantity quantityWithUnit:inches doubleValue:bloodGlucoseValue];

HKQuantityType *glucoseType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierBloodGlucose]; 
NSDate *now = [NSDate date];  
HKQuantitySample *bloodGlucosesample = [HKQuantitySample quantitySampleWithType:glucoseType quantity:glucoseQuantity startDate:now endDate:now];

[self.healthStore saveObject:bloodGlucosesample withCompletion:^(BOOL  success, NSError *error){

if (!success)           
{

NSLog(@"Error");

}

}];

}

如果我运行这个应用程序，会在以下代码行中遇到异常：

HKQuantitySample *bloodGlucosesample = [HKQuantitySample quantitySampleWithType:glucoseType quantity:glucoseQuantity startDate:now endDate:now];

跟踪：

似乎克不是HealthKit支持的单位。请在 SDK文档和此处检查允许的单位。 编辑：您为该值指定了错误的单位。

HKUnit *inches=[HKUnit gramUnit]; // this is not the right unit (nor inches)
HKQuantity * glucoseQuantity = [HKQuantity quantityWithUnit:inches doubleValue:bloodGlucoseValue];

您需要在Swift中创建一个质量单位和体积单位，然后将第一个单位除以第二个单位。

let milligramPerDeciLiter = HKUnit.gramUnitWithMetricPrefix(.Milli).unitDividedByUnit(HKUnit.literUnitWithMetricPrefix(.Deci))

在 Objc 中：

HKUnit* milligramPerDeciLiter = [[HKUnit gramUnitWithMetricPrefix:HKMetricPrefixMilli] unitDividedByUnit:[HKUnit literUnitWithMetricPrefix:HKMetricPrefixDeci]];
