我正在为Apple Watch制作锻炼应用程序,并在我的实际手表上使用HealthKit遇到了一些问题。
请求授权适用于模拟器和我的设备,并在每次启动时显示为成功。然而,查询和读取样本在我的设备上失败但在模拟器上失败。
启动后,成功授权,当需要查询或保存锻炼时,它会显示“授权未确定”。
两个权利都将HealthKit设置为YES,HealthKit和后台功能已打开,iOS Info.plist中提供了NSHealthShareUsageDescription和NSHealthUpdateUsageDescription键。
授权码
// Configure write values
let writeTypes: Set<HKSampleType> = [.workoutType(),
HKSampleType.quantityType(forIdentifier: .heartRate)!,
HKSampleType.quantityType(forIdentifier: .activeEnergyBurned)!,
HKSampleType.quantityType(forIdentifier: .stepCount)!,
HKSampleType.quantityType(forIdentifier: .distanceCycling)!,
HKSampleType.quantityType(forIdentifier: .distanceSwimming)!,
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课程)
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)
}
答案 0 :(得分:1)
我将授权代码放在我的ExtensionDelegate中,而不是我查询的同一个文件,它开始工作。
仍然奇怪的是它在模拟器上工作但在实际设备之前没有。
