由于未捕获的异常'

由于未捕获的异常'_HKObjectValidationFailureException'而终止应用(Terminating app due to uncaught exception '_HKObjectValidationFailureException')

我将血糖值保存到iOS中的Health Kit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"); } }]; }

如果我运行应用程序，我在这行代码中遇到以下异常：

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

I am saving the blood glucose values into Health Kit application in iOS.

-(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"); } }]; }

If I run the application, I got following exception in this line of code:

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

最满意答案

似乎克不是healthkit支持的单位。

检查SDK文档中的允许单位和此处

编辑：您为此值指定一个坏单位

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

您应该创建一个质量单位和体积单位，然后将第一个除以第二个（在swift中）：

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

在Objc：

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

It seems that grams is not an unit supported by healthkit.

Check the allowed units in the SDK documentation and here

Edit: You specify a bad unit for this value

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

You should create a mass unit and volume unit then divide the first by the second one (in swift):

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

In Objc :

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