Answer 1

Swift：Heart Rate（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 ：

 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) } }
