Question

使用healthKit框架，我尝试在健康应用程序中读取我的iPhone和Apple手表的步数。但是当我查询HKQuantitySample HKDevice个对象时，它没有显示localIdentifier和UDIDeviceIdentifier。知道为什么他们是空的吗？是因为来源没有记录信息？

请求

func getFitness() {
    let stepsCount = HKQuantityType.quantityTypeForIdentifier(
        HKQuantityTypeIdentifierStepCount)

    let stepsSampleQuery = HKSampleQuery(sampleType: stepsCount!,
        predicate: nil,
        limit: 10000,
        sortDescriptors: nil)  { 
          (query, results, error) in
            if let results = results as? [HKQuantitySample] {
                for result in results {
                    print("device: \(result.device) steps:\(result)" )
                }
            }
    }

    self.healthStore?.executeQuery(stepsSampleQuery)
}

HealthKit for iPhone和Apple Watch来源未记录localIdentifier和UDIDeviceIdentifier。
