导致此HealthKit错误的原因是：“将样本添加到锻炼中时发生错误”？
问题描述：
我理解为什么，但HealthKit提出的错误含糊不清是一个完整的黑盒子。为什么我收到错误：
I understand why, but the ambiguity of the errors that HealthKit puts out is a total black box. Why am I getting the error:
向训练中添加样本时出错：操作无法完成。
An error occurred while adding a sample to the workout: The operation couldn’t be completed.
我一直在搜索网络上的例子，但其中大多数都是迅速的。 :(
I've been scouring the web for examples, but most of them are in swift. :(
这是我的代码：
- (NSSet *)dataTypesToRead {
HKQuantityType *heartRate = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierHeartRate];
return [NSSet setWithObjects:heartRate, nil];
}
- (NSSet *)dataTypesToWrite {
HKWorkoutType* workout = [HKWorkoutType workoutType];
HKQuantityType *energyBurnedType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierActiveEnergyBurned];
return [NSSet setWithObjects:workout, energyBurnedType, nil];
}
- (void)saveWorkout {
HKHealthStore* healthStore = [[HKHealthStore alloc] init];
NSDate* timeOfWorkout = [NSDate date];
HKWorkoutType* type = [HKWorkoutType workoutType];
[healthStore requestAuthorizationToShareTypes:[self dataTypesToWrite]
readTypes:[self dataTypesToRead]
completion:^(BOOL success, NSError *error) {
if(success == YES)
{
// This sample uses hard-coded values and performs all the operations inline
// for simplicity's sake. A real-world app would calculate these values
// from sensor data and break the operation up using helper methods.
HKQuantity *energyBurned =
[HKQuantity quantityWithUnit:[HKUnit kilocalorieUnit]
doubleValue:333.0];
HKQuantity *distance =
[HKQuantity quantityWithUnit:[HKUnit mileUnit]
doubleValue:0.0];
// Provide summary information when creating the workout.
HKWorkout *workout = [HKWorkout workoutWithActivityType:HKWorkoutActivityTypeTraditionalStrengthTraining
startDate:timeOfWorkout
endDate:timeOfWorkout
duration:0
totalEnergyBurned:energyBurned
totalDistance:distance
metadata:nil];
// Save the workout before adding detailed samples.
[healthStore saveObject:workout withCompletion:^(BOOL success, NSError *error) {
if (!success) {
// Perform proper error handling here...
NSLog(@"*** An error occurred while saving the "
@"workout: %@ ***", error.localizedDescription);
abort();
}
}];
// Add optional, detailed information for each time interval
NSMutableArray *samples = [NSMutableArray array];
HKQuantityType *energyBurnedType =
[HKObjectType quantityTypeForIdentifier:
HKQuantityTypeIdentifierActiveEnergyBurned];
[samples addObject:energyBurnedType];
// Add all the samples to the workout.
[healthStore
addSamples:samples
toWorkout:workout
completion:^(BOOL success, NSError *error) {
if (!success) {
// Perform proper error handling here...
NSLog(@"*** An error occurred while adding a "
@"sample to the workout: %@ ***",
error.localizedDescription);
abort();
}
}];
}
else
{
// Determine if it was an error or if the
// user just canceld the authorization request
}
}];
}
答
这里我找到2个问题，
Here I find 2 issues,
- 在HealthKit中保存锻炼之前，您尝试将样本添加到锻炼中。
- 样本数组应包含HKQuantitySample或HKCategorySample类型的对象。
- Your trying to add samples to a workout before saving the workout in HealthKit.
- Samples array should contain objects of type HKQuantitySample or HKCategorySample.
这样工作正常......
This is working fine...
- (NSSet *)dataTypesToRead {
HKQuantityType *heartRate = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierHeartRate];
return [NSSet setWithObjects:heartRate, nil];
}
- (NSSet *)dataTypesToWrite {
HKWorkoutType* workout = [HKWorkoutType workoutType];
HKQuantityType *energyBurnedType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierActiveEnergyBurned];
return [NSSet setWithObjects:workout, energyBurnedType, nil];
}
- (void)saveWorkout {
HKHealthStore* healthStore = [[HKHealthStore alloc] init];
NSDate* timeOfWorkout = [NSDate date];
[healthStore requestAuthorizationToShareTypes:[self dataTypesToWrite]
readTypes:[self dataTypesToRead]

HKQuantity *energyBurned =
[HKQuantity quantityWithUnit:[HKUnit kilocalorieUnit]
doubleValue:333.0];
HKQuantity *distance =

// Provide summary information when creating the workout.
