ios - 已授予 HealthKit 授权并在模拟器上工作，但不在实际设备上工作

Question

我正在为 Apple Watch 开发健身应用程序，但在我的实际 watch 上使用 HealthKit 时遇到了一些问题。

请求授权在模拟器和我的设备上都有效，并且在每次启动时都显示为成功。然而，查询和读取样本在我的设备上失败了，但在模拟器上却没有。

启动后，授权成功，需要查询或保存锻炼时提示“授权未确定”。

两个权利都已将 HealthKit 设置为 YES，HealthKit 和后台功能已打开，NSHealthShareUsageDescription 和 NSHealthUpdateUsageDescription key 在 iOS Info.plist 中提供。

授权码

    let writeTypes: Set<HKSampleType> = [.workoutType(),
                                         HKSampleType.quantityType(forIdentifier: .heartRate)!,
                                         HKSampleType.quantityType(forIdentifier: .activeEnergyBurned)!,
                                         HKSampleType.quantityType(forIdentifier: .stepCount)!,
                                         HKSampleType.quantityType(forIdentifier: .distanceCycling)!,

                                         HKSampleType.quantityType(forIdentifier: .distanceWalkingRunning)!,
                                         HKSampleType.quantityType(forIdentifier: .swimmingStrokeCount)!]
    // Configure read values
    let readTypes: Set<HKObjectType> = [.activitySummaryType(), .workoutType(),
                                        HKObjectType.quantityType(forIdentifier: .heartRate)!,
                                        HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!,
                                        HKObjectType.quantityType(forIdentifier: .stepCount)!,
                                        HKObjectType.quantityType(forIdentifier: .distanceCycling)!,
                                        HKObjectType.quantityType(forIdentifier: .distanceSwimming)!,
                                        HKObjectType.quantityType(forIdentifier: .distanceWalkingRunning)!,
                                        HKObjectType.quantityType(forIdentifier: .swimmingStrokeCount)!]

    // Create health store
    let healthStore = HKHealthStore()

    // Use it to request authorization for our types
    healthStore.requestAuthorization(toShare: writeTypes, read: readTypes) { (success, error) in
        if success {
            print("Success: authorization granted")
        } else {
            print("Error: \(error?.localizedDescription ?? "")")
        }
    }

查询代码(Udemy类(class))

func startQuery(_ quantityTypeIdentifier: HKQuantityTypeIdentifier) {
    // We only want data points after our workout start date
    let datePredicate = HKQuery.predicateForSamples(withStart: workoutStartDate, end: nil, options: .strictStartDate)
    // And from our current device
    let devicePredicate = HKQuery.predicateForObjects(from: [HKDevice.local()])
    // Combine them
    let queryPredicate = NSCompoundPredicate(andPredicateWithSubpredicates: [datePredicate, devicePredicate])
    // Write code to receive results from our query
    let updateHandler: (HKAnchoredObjectQuery, [HKSample]?, [HKDeletedObject]?, HKQueryAnchor?, Error?) -> Void = { query, samples, deletedObjects, queryAnchor, error in

        //safely typecast to a quantity sample so we can read values
        guard let samples = samples as? [HKQuantitySample] else { return }

        //process the samples
        print("Start processing samples")
        self.process(samples, type: quantityTypeIdentifier)
    }

    // Create the query out of our type (e.g. heart rate), predicate and result handling code
    let quantityType = HKObjectType.quantityType(forIdentifier: quantityTypeIdentifier)!
    let query = HKAnchoredObjectQuery(type: quantityType, predicate: queryPredicate, anchor: nil, limit: HKObjectQueryNoLimit, resultsHandler: updateHandler)

    // Tell HealthKit to re-run the code every time new data is available
    query.updateHandler = updateHandler

    // Start the query running
    healthStore.execute(query)

    // Stach it away so we can stop it later
    activeDataQueries.append(query)
}

我将授权代码放在我的 ExtensionDelegate 中，而不是我正在查询的同一个文件中，它开始工作。

之前它在模拟器上运行但在实际设备上运行不正常，这仍然很奇怪。
