HKObjectQuery完成处理程序仅在watch处于活动状态时触发？

Question

使用下面的代码，我在Apple Watch上查询distanceWalkingAndRunning个样本，我想返回给我（即在用户移动时实时调用完成处理程序），但是，在测试中...当我移动时，不会调用完成处理程序，只有当我抬起手腕并激活手表时才会调用它？如果可能的话，我希望在后台收集这些数据。在锻炼开始时会触发查询，这些都与awake或willActivate函数无关？

func startWalkingRunningQuery(from startDate: Date, updateHandler: @escaping ([HKQuantitySample]) -> Void) {
        let typeIdentifier = HKQuantityTypeIdentifier.distanceWalkingRunning
        startQuery(ofType: typeIdentifier, from: startDate) { _, samples, _, _, error in
            guard let quantitySamples = samples as? [HKQuantitySample] else {
                print("Distance walking running query failed with error: \(String(describing: error))")
                return
            }

            updateHandler(quantitySamples)

        }
    }

  //Generic helper function 
    private func startQuery(ofType type: HKQuantityTypeIdentifier, from startDate: Date, handler: @escaping
        (HKAnchoredObjectQuery, [HKSample]?, [HKDeletedObject]?, HKQueryAnchor?, Error?) -> Void) {
        let datePredicate = HKQuery.predicateForSamples(withStart: startDate, end: nil, options: .strictStartDate)
        let devicePredicate = HKQuery.predicateForObjects(from: [HKDevice.local()])
        let queryPredicate = NSCompoundPredicate(andPredicateWithSubpredicates:[datePredicate, devicePredicate])

        let quantityType = HKObjectType.quantityType(forIdentifier: type)!

        let query = HKAnchoredObjectQuery(type: quantityType, predicate: queryPredicate, anchor: nil,
                                          limit: HKObjectQueryNoLimit, resultsHandler: handler)
        query.updateHandler = handler
        healthStore.execute(query)

        activeDataQueries.append(query)
    }
