【问题描述】：

是否可以从 HealthKit 读取 Apple Watch 移动目标？

我可以使用数量标识符 HKQuantityTypeIdentifier.activeEnergyBurned 检索移动值。我找不到移动目标的类似标识符。

【参考方案1】：

//Declared globally
var healthStore: HKHealthStore?

func prepareHealthKit() 
    guard HKHealthStore.isHealthDataAvailable() else 
        return
    

    var readTypes = Set<HKObjectType>()
    readTypes.insert(HKObjectType.activitySummaryType())

    healthStore = HKHealthStore()
    healthStore!.requestAuthorization(toShare: nil, read: readTypes)  (isSuccess, error) in
        /*
         Assuming you know the following steps:
         1. Start workout session: i.e. "HKWorkoutSession"
         2. Wait for delegate: i.e "workoutSession(_:didChangeTo:from:date:)"
         3. Start Query for Activity Summary in the delegate:
            i.e our "startQueryForActivitySummary()"
         */

func startQueryForActivitySummary() 
    func createPredicate() -> NSPredicate? 
        let calendar = Calendar.autoupdatingCurrent

        var dateComponents = calendar.dateComponents([.year, .month, .day],
                                                     from: Date())
        dateComponents.calendar = calendar

        let predicate = HKQuery.predicateForActivitySummary(with: dateComponents)
        return predicate
    

    let queryPredicate = createPredicate()
    let query = HKActivitySummaryQuery(predicate: queryPredicate)  (query, summaries, error) -> Void in
        if let summaries = summaries 
            for summary in summaries 
                let activeEnergyBurned = summary.activeEnergyBurned.doubleValue(for: HKUnit.kilocalorie())
                let activeEnergyBurnedGoal = summary.activeEnergyBurnedGoal.doubleValue(for: HKUnit.kilocalorie())
                let activeEnergyBurnGoalPercent = round(activeEnergyBurned/activeEnergyBurnedGoal)

                print(activeEnergyBurnGoalPercent)
            
        
    

    healthStore?.execute(query)

谢谢。在使用以下方法启用健康包访问后，这对我来说非常有效：***.com/questions/37863093/…

【参考方案2】：

我得到了答案。移动目标可从HKActivitySummary 访问。

您应该请求读取 HKActivitySummaryType 的权限：

 let activitySummaryType = HKActivitySummaryType.activitySummaryType()
 let readDataTypes: Set<HKObjectType> = [activitySummaryType]
 healthStore.requestAuthorization(toShare: nil, read: readDataTypes, completion: myCompletionHandler)

然后使用HKActivitySummaryQuery阅读摘要信息

let query = HKActivitySummaryQuery(predicate: myPredicate)  (query, summaries, error) -> Void in
    if error != nil 
        fatalError("*** Did not return a valid error object. ***")
    

    if let activitySummaries = summaries 
        for summary in activitySummaries 
            print(summary.activeEnergyBurnedGoal)
            //do something with the summary here...
        
    

healthStore.execute(query)

可从 HKActivitySummary 访问的其他活动摘要数据可通过here 获取。

您的示例不完整。我将您的代码复制到一个新项目中，但无法正常工作。
