ios8 - HealthKit HKSampleQuery 心率读数

Question

我正在尝试使用 HKSampleQuery 通过 healthkit 商店获取心率读数，但我一直在获取 count/s。无论如何我可以通过计数/分钟得到它吗？

Answer 1

Try using something like the following in the completion handler of a HKSampleQuery

let result = results?.last as HKQuantitySample
let quantity = result.quantity
let count = quantity.doubleValueForUnit(HKUnit(fromString: "count/min"))
