iOS模拟器无法读取我保存的健康数据

Question

我创建了一个应用程序来保存和读取一些运行和步行锻炼数据到 HealthKit。我设法保存了数据，并在模拟器的 Health 应用程序上查看了它，但是当我尝试读取数据时，样本计数为 0。如果有人能帮我解决这个问题，我将不胜感激。

Xcode 12.5.1 / iOS 14.5

func AuthenticateHealthKit() {

  print("AuthenticateHealthKit")

  let typesToShare: Set = [
    HKQuantityType.workoutType()
  ]

  let typesToRead: Set = [
    HKQuantityType.workoutType(),
    HKQuantityType.quantityType(forIdentifier: .distanceWalkingRunning)!,
    HKQuantityType.quantityType(forIdentifier: .height)!,
  ]

  healthStore.requestAuthorization(toShare: typesToShare, read: typesToRead) { (success, error) in
    if !success {
      fatalError("Error requesting authorization from health store: \(String(describing: error)))")
    } else {
      print("Authenticated!")
    }
  }

}

func SaveData() {

  let configuration = HKWorkoutConfiguration()
  configuration.activityType = .running
  configuration.locationType = Int.random(in: 0..<2) == 0 ? .indoor : .outdoor

  let startDate = now - (86400 * 60.0)
  let duration = 120.0
  let endDate = startDate + duration
  let quantity = HKQuantity(unit: HKUnit.kilocalorie(), doubleValue: 20.0)
  let distance = HKQuantity(unit: HKUnit.meter(), doubleValue: 1200)

  let workout = HKWorkout(
    activityType: configuration.activityType, start: startDate, end: endDate, duration: duration,
    totalEnergyBurned: quantity, totalDistance: distance,
    metadata: [HKMetadataKeyIndoorWorkout: true])

  healthStore.save(workout) { success, _ in

    if success {
      print("SAVED WORKOUT!!!")
    } else {
      print("COULD NOT SAVE WORKOUT!!!")
    }

  }

}

func ReadData() {

  let start = now - (86400 * 60.0)
  let end = now
  let predicate = HKQuery.predicateForSamples(withStart: start, end: end, options: [])
  print("start : \(start)")

  guard HKHealthStore.isHealthDataAvailable() else {
    print("No data available!")
    return
  }

  guard
    let sampleType = HKSampleType.quantityType(
      forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning)
  else {
    fatalError("*** This method should never fail ***")
  }

  let query = HKSampleQuery(
    sampleType: sampleType, predicate: predicate, limit: Int(HKObjectQueryNoLimit),
    sortDescriptors: nil
  ) {
    query, results, error in

    guard let samples = results as? [HKQuantitySample] else {
      print("Error")
      return
    }

    for sample in samples {
      print("sample : \(sample.quantity) \(sample.quantityType)")
    }

    DispatchQueue.main.async {
      print("Update UI : \(samples.count)")
    }
  }

    healthStore.execute(query)

}

这里是 ReadData 方法的输出

start : 2021-08-14 21:38:35 +0000
Authenticated!
Update UI : 0

以下是 Health App 数据和权限（全部在模拟器上）

Answer 1

您正在写锻炼但想阅读远距离步行+运行。在锻炼中节省距离属性并不会节省步行距离+运行样本。您需要创建该类型的样本，为其请求授权，然后使用 HKHealthStore 上的 addSamples 方法保存并关联锻炼。

最好使用 HKWorkoutBuilder，它的 beginCollection/add/endCollection/finishWorkout 方法会为您创建合适的 HKWorkout 对象。

Answer 2

我已经设法保存了可以使用 ReadData 方法读取的数据（查看原始问题）。这是新的 SaveData 方法：

let now = Date()

func SaveData() {

        let configuration = HKWorkoutConfiguration()
        configuration.activityType = .running
        configuration.locationType = Int.random(in: 0..<2) == 0 ? .indoor : .outdoor

        let builder = HKWorkoutBuilder(healthStore: healthStore, configuration: configuration, device: .local())

        let sample = HKCumulativeQuantitySample(type: HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning)!, quantity: HKQuantity.init(unit: HKUnit.meter(), doubleValue: 1230), start: now - 3600, end: now)

        builder.add([sample]) { success, error in

            guard success else {
                print("Error!")
                return
            }

            print("Added Sample")

        }

    }
