当尝试为 Healthkit 设置观察者查询时，对于很多用户来说，我收到了授权未确定的错误。
经过一番研究后，我发现只有在尝试向 Healthkit 写入(共享)数据时才会发生这样的错误。根据 Apple HK 文档 - 当尝试读取用户未授予权限的数据时，我根本不应该获取任何数据(没有任何错误)，就好像没有新数据一样。
这是我用来设置观察者查询的代码:
class func setObserver(healthKitManager manager: HealthKitManager, forType type: HKSampleType?, withPredicateAfterFetching predicate: NSPredicate?) {
guard type != nil && manager.healthStore != nil else {
return
}
let query = HKObserverQuery.init(sampleType: type!, predicate: nil) { (query, completionHandler, error) in
guard error == nil else {
SimpleEvent(name: "HKObserverQuery failed", param: "type:\(type!.identifier), error: \(error!.localizedDescription)").fire()
return
}
let anchoredQuery = HKAnchoredObjectQuery.init(type: type!, predicate: predicate, anchor: manager.getHealthDataAnchor(forType: type!), limit: HKObjectQueryNoLimit, resultsHandler: { (query, results, deletedObjects, newAnchor, error) in
guard error == nil else {
SimpleEvent(name: "HKAnchoredQuery failed", param: "type:\(type!.identifier), error: \(error!.localizedDescription)").fire()
return
}
\\ Code that saves the HK Data
completionHandler()
})
manager.healthStore!.execute(anchoredQuery)
}
manager.healthStore!.execute(query)
manager.observerQueries.append(query)
}
HKObserverQuery failed 事件捕获该错误。
正如我提到的，权限请求不应影响数据读取，但无论如何，这里是代码:
func requestAuthorizationToShareTypesAndReadTypes(withSuccess successBlock: @escaping () -> Void, failure failureBlock: @escaping () -> Void) {
self.healthStore?.requestAuthorization(toShare: writeDataTypes as! Set<HKSampleType>, read: readDataTypes as! Set<HKObjectType>, completion: { (success, error) in
if !success || error != nil {
SimpleEvent.init(name: "HK-requestAuthorization", param: error!.localizedDescription)
NSLog("You didn't allow HealthKit to access these read/write data types. The error was: %@.", error as! NSError);
failureBlock()
return;
}
self.userHaveBeenPromptWithPermissionsScreenAtLeastOnce = true
self.enableBackgroundDelivery()
successBlock()
})
}
这是我启用后台交付的部分
func enableBackgroundDelivery() {
for type in self.readDataTypes! {
if let type = type as? HKSampleType {
self.enableBackgroundDelivery(forSampleType: type)
}
}
}
func enableBackgroundDelivery(forSampleType type:HKSampleType) {
self.healthStore?.enableBackgroundDelivery(for: type, frequency: HKUpdateFrequency.immediate, withCompletion: { (success, error) in
if error != nil {
print(String.init(format: "HK-BackgoundError: error:%@, user: %@, type: %@", error!.localizedDescription, NRManager.shared().username, type.identifier))
}
})
}
最佳答案
从 HealthKit 读取数据需要授权。如果您收到指示未确定授权的错误，则表明尚未提示用户授权您的应用读取或写入您正在查询的类型的示例。
关于ios - HKObserverQuery 失败，授权未确定，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46142575/
