Question

我在我的应用中集成了HealthKit。但是当我授权HealthKitStore时，它将不允许我授权。以下是我用于授权HealthKitStore的代码：

 var healthStore: HKHealthStore = HKHealthStore()

 let dataTypesToWrite = [
  HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierBodyMass),
  HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeight),
  HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierBodyMassIndex)
]

let dataTypesToRead = [
  HKObjectType.characteristicTypeForIdentifier(HKCharacteristicTypeIdentifierDateOfBirth),
  HKObjectType.characteristicTypeForIdentifier(HKCharacteristicTypeIdentifierBiologicalSex),
  HKObjectType.characteristicTypeForIdentifier(HKQuantityTypeIdentifierStepCount)
]

healthStore.requestAuthorizationToShareTypes(Set<NSObject>(arrayLiteral: dataTypesToWrite),
  readTypes: Set<NSObject>(arrayLiteral: dataTypesToRead), completion: {
    (success, error) in
    if success {
      println("User completed authorisation request.")
    } else {
      println("The user cancelled the authorisation request. \(error)")
    }
})

但是当我运行我的应用程序时，我收到以下错误：

该异常表示您正在将包含HKObjectTypes数组的Set传递给HealthKit。它应该是一组HKObjectTypes。
