我想检索指示用户是否在这个时间站立的值。
我还希望能够检索当天的StandHours计数。
以下是我一直试图理解的苹果链接，以便从healthKit获取价值。我提供这些链接，以帮助提供对我所寻找内容的理解，并帮助您回答我的问题。

布鲁诺的回答只是答案的一半。例如。他的＆＃34; sandunit＆＃34;变量是他如何拉动用户今天的小时数。我测试了它。我也纠正了他的代码中的拼写错误。 :)。此外，我假设它必须从摘要var的范围内拉出。
我在stackOverflow上发现了另一个可能提供一些线索的问题。我认为他们设法通过HKCategoryTypeIdentifier提取值。 Watch os 2.0 beta: access heart beat rate

我是HealthKit的新手，所以也许有更好的方法可以做到这一点。但这似乎对我有用。我查看了实际的站立时间，并使用minutes > 0致电完成处理程序。
private let store = HKHealthStore()
func askPermission() {
let standType = HKQuantityType.quantityType(forIdentifier: .appleStandTime)!
store.requestAuthorization(toShare: [], read: [standType], completion: { (success, error) in
self.didStandThisHour { (didStand) in
print("Did stand this hour: \(didStand)")
}
})
}
func didStandThisHour(_ didStand: @escaping (Bool) -> ()) {
let store = HKHealthStore()
let calendar = Calendar.autoupdatingCurrent
let dateComponents = calendar.dateComponents([.year, .month, .day, .hour], from: Date())
let endDate = Date()
let startDate = calendar.date(from: dateComponents)!
let standTime = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.appleStandTime)!
var interval = DateComponents()
interval.hour = 1
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate)
let query = HKStatisticsCollectionQuery(quantityType: standTime, quantitySamplePredicate: predicate, options: [.cumulativeSum], anchorDate: startDate, intervalComponents:interval)
query.initialResultsHandler = { query, results, error in
guard error == nil, let myResults = results else {
fatalError("Something is wrong with HealthKit link")
}
myResults.enumerateStatistics(from: startDate, to: endDate, with: { (statistics, stop) in
guard let quantity = statistics.sumQuantity() else {
didStand(false)
return
}
let minutes = quantity.doubleValue(for: .minute())
didStand(minutes > 0)
})
}
store.execute(query)
}

好的，如果您想要检索今天的活动响铃信息（包括停留时间），您首先请求您要检索的对象类型的用户授权：
let healthStore = HKHealthStore()
let objectTypes: Set<HKObjectType> = [
HKObjectType.activitySummaryType()
]
healthStore.requestAuthorization(toShare: nil, read: objectTypes) { (success, error) in
// Authorization request finished, hopefully the user allowed access!
}
然后您可以使用此谓词来检索今天的日期：
let calendar = Calendar.autoupdatingCurrent
var dateComponents = calendar.dateComponents(
[ .year, .month, .day ],
from: Date()
)
// This line is required to make the whole thing work
dateComponents.calendar = calendar
let predicate = HKQuery.predicateForActivitySummary(with: dateComponents)
创建查询...
let query = HKActivitySummaryQuery(predicate: predicate) { (query, summaries, error) in
guard let summaries = summaries, summaries.count > 0
else {
return
}
// Handle data
}
您收到的数据类型为HKActivitySummary，您可以检索，例如：
let sandUnit = HKUnit.count()
let standHours = summary.appleStandHours.doubleValue(for: standUnit)
