我需要一些帮助来实现我的应用程序中的 HealthKit。我正在使用 Swift 4 Xcode 9。我正在使用以下代码来获取特定日期的用户步数:
func getTodaysSteps(completion: @escaping (Double) -> Void) {
let stepsQuantityType = HKQuantityType.quantityType(forIdentifier: .stepCount)!
let now = Date()
let startOfDay = Calendar.current.startOfDay(for: now)
let predicate = HKQuery.predicateForSamples(withStart: startOfDay, end: now, options: .strictStartDate)
let query = HKStatisticsQuery(quantityType: stepsQuantityType, quantitySamplePredicate: predicate, options: .cumulativeSum) { (_, result, error) in
var resultCount = 0.0
guard let result = result else {
// log.error("Failed to fetch steps = \(error?.localizedDescription ?? "N/A")")
completion(resultCount)
return
}
if let sum = result.sumQuantity() {
resultCount = sum.doubleValue(for: HKUnit.count())
}
DispatchQueue.main.async {
completion(resultCount)
}
}
healthStore.execute(query)
}
现在我想获取整个月中每一天的用户步数和卡路里。换句话说，我想让用户以周、月和年的格式计算过去的步数。谁能帮我做同样的事情？
最佳答案
您只需要设置开始日期(在您的情况下可能是 aWeekAgo、aMothAgo、aYearAgo)并且 toDate 是当前日期
let sevneDaysAgo = NSCalendar.current.date(byAdding: .day, value: -7, to: Date())
let currentDate = Date.init()
PedometerManager.shared.getPedometerDataFromDate(fromDate: sevneDaysAgo, toDate: currentDate) { [weak self] (data, error, errorMsg) in
if(error == nil && data != nil) {
if let count = data?.numberOfSteps {
}
if let distance = data?.distance {
let roundDis = round(distance.doubleValue)
let dis = String.init(format: "%.3f",roundDis)
}
if let pace = data?.currentPace {
}
if let cadence = data?.currentCadence {
}
if let ascend = data!.floorsAscended {
}
if let desc = data!.floorsDescended {
}
if let activity = self?.activityName {
}
}
}
你必须使用 CMPedometer 类
关于ios - 快速从 healthkit 中获取周、月和年格式的用户数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47829264/
