如果用户不允许某些条目类型,HealthKit 无法使用多个条目编写 HKSample

HealthKit unable to write HKSample with multiple entries if some of the entry types are disallowed by user

假设一个应用请求授权将脂肪和碳水化合物写入 HealthKit:

func dataTypesToWrite() -> NSSet {
    return NSSet(objects:
        HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryCarbohydrates)!,
        HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryFatTotal)!
    )
}

healthStore.requestAuthorization(toShare: dataTypesToWrite() as? Set<HKSampleType>, read: nil, completion: { (success, error) -> Void in
    if success {
        print("completed")
    }
})

这将提示用户允许应用写入 HealthKit。如果用户允许同时写入脂肪和碳水化合物,则一切都很好。但是,如果他们只选择允许一个,并且将带有脂肪和碳水化合物的 HKSample 写入 HealthKit,则该条目将不会显示:

func foodCorrelationForFoodItem(foodNutrients: Dictionary<String, Double>, foodTitle: String) -> HKCorrelation {
    let nowDate: Date = Date()

    let consumedSamples: Set<HKSample> = [
        HKQuantitySample(
            type: HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryCarbohydrates)!,
            quantity: HKQuantity(unit: HKUnit.gram(), doubleValue: 5.0),
            start: nowDate,
            end: nowDate),
        HKQuantitySample(
            type: HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.dietaryFatTotal)!,
            quantity: HKQuantity(unit: HKUnit.gram(), doubleValue: 10.0),
            start: nowDate,
            end: nowDate)
    ]

    let foodType: HKCorrelationType = HKCorrelationType.correlationType(forIdentifier: HKCorrelationTypeIdentifier.food)!
    let foodCorrelationMetadata: [String: AnyObject] = [HKMetadataKeyFoodType: foodTitle as AnyObject]

    let foodCorrelation: HKCorrelation = HKCorrelation(type: foodType, start: nowDate, end: nowDate, objects: consumedSamples, metadata: foodCorrelationMetadata)

    return foodCorrelation
}


self.healthStore.save(foodCorrelationForFoodItem) { (success, error) in
    if let error = error {
        print(error)
    }
}

由于 Apple 不允许应用程序查看哪些 HealthKit 项目是可写的,因此无法检测到例如应该只写脂肪。有针对这个的解决方法吗?谢谢

A​​pple 不允许应用查询它可以写入哪些 HealthKit 类型,这不是真的。您可能会想到不可查询的读取授权。您可以在 HKHealthStoredetermine whether your app has write authorization 上使用 authorizationStatus(for:)。如果它 returns notDeterminedsharingDenied 那么您的应用没有授权。
