如何将一系列 HKQuantity 样本（心率）保存到锻炼中

Question

Apple 的文档示例代码通过 add 方法将平均心率 HKQuantitySample 保存到锻炼中，但是对于给定的锻炼，我试图保存锻炼期间获取的所有心率值，即[HKQuantitySample] 我该怎么做？下面是我的代码添加第一个值只是为了测试，但我想全部添加？

 var heartRateValues = [HKQuantitySample]()

 func processHeartRateSamples(_ samples: [HKQuantitySample]) {
        for sample in samples {
            heartRateValues.append(sample)
        }    
    }

private func addSamples(toWorkout workout: HKWorkout, from startDate: Date, to endDate: Date) {
        // Create energy and distance samples
        let totalEnergyBurnedSample = HKQuantitySample(type: HKQuantityType.activeEnergyBurned(),
                                                       quantity: totalEnergyBurnedQuantity(),
                                                       start: startDate,
                                                       end: endDate)

        let totalDistanceSample = HKQuantitySample(type: HKQuantityType.distanceWalkingRunning(),
                                                   quantity: totalDistanceQuantity(),
                                                   start: startDate,
                                                   end: endDate)





        // Add samples to workout
        healthStore.add([totalEnergyBurnedSample, totalDistanceSample, heartRateValues.first!], to: workout) { (success: Bool, error: Error?) in
            guard success else {
                print("Adding workout subsamples failed with error: \(String(describing: error))")
                return
            }


            }
        }

您已经有 heartRateValues 作为 [HKQuantitySample] 所以只需这样做：

private func addSamples(toWorkout workout: HKWorkout, from startDate: Date, to endDate: Date) {
    // Create energy and distance samples
    let totalEnergyBurnedSample = HKQuantitySample(type: HKQuantityType.activeEnergyBurned(),
                                                   quantity: totalEnergyBurnedQuantity(),
                                                   start: startDate,
                                                   end: endDate)

    let totalDistanceSample = HKQuantitySample(type: HKQuantityType.distanceWalkingRunning(),
                                               quantity: totalDistanceQuantity(),
                                               start: startDate,
                                               end: endDate)

    let samples = [HKQuantitySample]()
    samples.append(totalEnergyBurnedSample)
    samples.append(totalDistanceSample)
    samples.append(contentsOf: heartRateValues)

    // Add samples to workout
    healthStore.add(samples, to: workout) { (success: Bool, error: Error?) in
        guard success else {
            print("Adding workout subsamples failed with error: \(String(describing: error))")
            return
        }


        }
    }

基本上你创建一个样本数组添加totalEnergyBurnedSample和totalDistanceSample然后整个heartRateValues数组然后在healthStore.add方法中传递那个sample参数...
