Answer 1

Swift:心率(bpm)保存到healthkit商店

 private func saveHeartRateIntoHealthStore(height:Double) -> Void
    {
        // Save the user's heart rate into HealthKit.
        let heartRateUnit: HKUnit = HKUnit.countUnit().unitDividedByUnit(HKUnit.minuteUnit())
        let heartRateQuantity: HKQuantity = HKQuantity(unit: heartRateUnit, doubleValue: height)

        var heartRate : HKQuantityType = HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)
        let nowDate: NSDate = NSDate()

        let heartRateSample: HKQuantitySample = HKQuantitySample(type: heartRate
            , quantity: heartRateQuantity, startDate: nowDate, endDate: nowDate)

        let completion: ((Bool, NSError!) -> Void) = {
            (success, error) -> Void in

            if !success {
                println("An error occured saving the Heart Rate sample \(heartRateSample). In your app, try to handle this gracefully. The error was: \(error).")

                abort()
            }

        }

        self.healthStore!.saveObject(heartRateSample, withCompletion: completion)

    }// end saveHeartRateIntoHealthStore

Answer 2

在Swift 3中：

func saveHeartRate(date: Date = Date(), heartRate heartRateValue: Double, completion completionBlock: @escaping (Bool, Error?) -> Void) {
    let unit = HKUnit.count().unitDivided(by: HKUnit.minute())
    let quantity = HKQuantity(unit: unit, doubleValue: heartRateValue)
    let type = HKQuantityType.quantityType(forIdentifier: .heartRate)!

    let heartRateSample = HKQuantitySample(type: type, quantity: quantity, start: date, end: date)

    self.healthKitStore.save(heartRateSample) { (success, error) -> Void in
        if !success {
            print("An error occured saving the HR sample \(heartRateSample). In your app, try to handle this gracefully. The error was: \(error).")
        }
        completionBlock(success, error)
    }
}
