我正在创建一个Fitness health应用程序,其中必须从Health kit中显示用户的实时卡路里及其心率。我获得了权限。但是我不知道如何获取卡路里和心率。
这是代码的许可。
static let healthKitStore = HKHealthStore()
// MARK:- Health Kit Permissions :-
static func authorizeHealthKit() {
// HKQuantityTypeIdentifierBodyMass - For Weight
var shareTypes = Set<HKSampleType>()
shareTypes.insert(HKSampleType.workoutType())
shareTypes.insert(HKSampleType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!)
shareTypes.insert(HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierDistanceWalkingRunning)!)
shareTypes.insert(HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)!)
var readTypes = Set<HKObjectType>()
readTypes.insert(HKObjectType.workoutType())
readTypes.insert(HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!)
readTypes.insert(HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierDistanceWalkingRunning)!)
readTypes.insert(HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)!)
healthKitStore.requestAuthorizationToShareTypes(shareTypes, readTypes: readTypes) { (success, error) -> Void in
if success {
print("success")
} else {
print("failure")
}
if let error = error {
print(error)
}
}
}
获得成功后,我需要卡路里和心率,这些功能或代码我必须使用。像 Fitbit Apis 一样返回数据,或者有 Apple Api的可以返回数据吗?
最佳答案
检查此代码:
let tHeartRate = HKSampleType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)
let tHeartRateQuery = HKSampleQuery(sampleType: tHeartRate!, predicate:.None, limit: 0, sortDescriptors: nil) { query, results, error in
if results?.count > 0
{
var string:String = ""
for result in results as! [HKQuantitySample]
{
let HeartRate = result.quantity
string = "\(HeartRate)"
print(string)
}
}
}
self.healthKitStore.executeQuery(tHeartRateQuery)
