iOS HealthKit 项目使用 HKActivitySummaryQuery - 摘要始终为零

Question

Objective：从 HealthKit 中读取我的 Activity 数据（即 activity 环形数据 - 移动卡路里、锻炼分钟数和站立次数）

遇到的问题：结果处理程序returns 'nil' HKActivity摘要数组

我尝试过的：

我已将 HealthKit Capability 添加到项目中并添加了两个 info.plist 要求：

Privacy - Health Share Usage Description

Privacy - Health Update Usage Description

并确保在 iPhone.

中出现针对 HealthKit 的权限请求弹出窗口时，我点击了“全部允许”以获得权限

我也有很多周的 activity 数据记录，所以应该没问题。

如何检索 HKActivitySummary 对象数组，以便在我的 iOS 应用程序中复制环。

我的代码：

override func viewDidLoad() {
  super.viewDidLoad() 
  startQueryForActivitySummary(view: self.view)
}

func startQueryForActivitySummary(view: UIView) {
  
  let calendar = NSCalendar.current
  let endDate = Date()
  
  guard let startDate = calendar.date(byAdding: .day, value: -7, to: endDate) else {
    fatalError("*** Unable to create the start date ***")
  }
  
  let units: Set<Calendar.Component> = [.day, .month, .year, .era]
  var startDateComponents = calendar.dateComponents(units, from: startDate)
  startDateComponents.calendar = calendar
  var endDateComponents = calendar.dateComponents(units, from: endDate)
  endDateComponents.calendar = calendar
  
  let queryPredicate = HKQuery.predicate(forActivitySummariesBetweenStart: startDateComponents,
                                         end: endDateComponents)
  let query = HKActivitySummaryQuery(predicate: queryPredicate) { (query, summaries, error) -> Void in
    if let summaries = summaries { // print(summaries) before this line will always return nil.
      if let summary = summaries.first {
        let activeEnergyBurned = summary.activeEnergyBurned.doubleValue(for: HKUnit.kilocalorie())
        let activeEnergyBurnedGoal = summary.activeEnergyBurnedGoal.doubleValue(for: HKUnit.kilocalorie())
        let activeEnergyBurnGoalPercent = round(activeEnergyBurned/activeEnergyBurnedGoal)
        
        let frame    = CGRect(x: 0, y: 0, width: 200, height: 200)
        let ringView = HKActivityRingView(frame: frame)
        view.addSubview(ringView)
        ringView.setActivitySummary(summary, animated: true)
      }
    }
  }
  
  let allTypes = Set([HKObjectType.workoutType(),
                      HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!])
  
  let healthStore = HKHealthStore()
  healthStore.requestAuthorization(toShare: allTypes, read: allTypes) { (success, error) in 
    healthStore.execute(query)
  }
}

Answer 1

我认为您缺少权限 HKObjectType.activitySummaryType()

像这样扩展你的类型：

    let allTypes = Set([
            HKObjectType.workoutType(),
            HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!,
            HKObjectType.activitySummaryType()
        ])
