1、配置工程

注意：Team这个地方必须是企业的或者是公司的，不能是Personal Team。如下图

2、设置Capabilities

设置完了之后，左侧会出现 XZHealthDemo.entitlements。如下图：

3、设置 Info.plist

注意：描述语句只能写 "some string value stating the reason"，其他的都会崩溃。

Privacy - Health Share Usage Description  // 读取权限
some string value stating the reason
Privacy - Health Update Usage Description // 写入权限
some string value stating the reason或者
<key>NSHealthShareUsageDescription</key>
<string>some string value stating the reason</string>
<key>NSHealthUpdateUsageDescription</key>
<string>some string value stating the reason</string>

4、错误解决

出现错误：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthUpdateUsageDescription must be set in the app's Info.plist in order to request write authorization for the following types: HKQuantityTypeIdentifierStepCount'

解决同 3 设置Info.plist

5、代码编写

1>判断设备是否支持 HealthKit 框架

func isHealthDataAvailable() -> Bool

2>判断是否支持健康记录，iOS 12.0 以上系统

func supportsHealthRecords() -> Bool

3>某一种健康类型的支持状态

func authorizationStatus(for type: HKObjectType) -> HKAuthorizationStatusHKAuthorizationStatus 有3种结果：
notDetermined // 不确定
sharingDenied  // 不允许
sharingAuthorized // 允许

4>请求读写权限：在用户读取和写入数据之前，需要请求是否有权限。

要自定义显示在授权表上的消息，请在您的应用程序中设置以下键 Info.plist 中：

设置NSHealthShareUsageDescription键，自定义用于读取数据的消息。

设置NSHealthUpdateUsageDescription键，自定义用于编写数据的消息。

func requestAuthorization(toShare typesToShare: Set<HKSampleType>?, read typesToRead: Set<HKObjectType>?, completion: @escaping (Bool, Error?) -> Void)

5>是否有读写的权限，iOS 12.0 系统以上

func getRequestStatusForAuthorization(toShare typesToShare: Set<HKSampleType>, read typesToRead: Set<HKObjectType>, completion: @escaping (HKAuthorizationRequestStatus, Error?) -> Void)

6>保存某个数据

func save(_ object: HKObject, withCompletion completion: @escaping (Bool, Error?) -> Void)

7>保存多个数据

func save(_ objects: [HKObject], withCompletion completion: @escaping (Bool, Error?) -> Void)

8>执行查询方法

func execute(_ query: HKQuery)

9>停止查询

func stop(_ query: HKQuery)

导入HealthKit框架

import HealthKit

授权读写步数

    /// 授权 步数 读写func authorizeStepCount(completed: @escaping ((_ isSuccess: Bool)->Void)) {if HKHealthStore.isHealthDataAvailable() {let writeTypes = stepCountToWrite()let readTypes = stepCountToRead()healthStore.requestAuthorization(toShare: writeTypes, read: readTypes) { (success, error) incompleted(success)print("----步数读写：", success)}}}/// 步数 读 权限func stepCountToRead() -> Set<HKQuantityType>? {let stepType = HKQuantityType.quantityType(forIdentifier: .stepCount)return Set(arrayLiteral: stepType!)}/// 步数 写 权限func stepCountToWrite() -> Set<HKQuantityType>? {let stepType = HKQuantityType.quantityType(forIdentifier: .stepCount)return Set(arrayLiteral: stepType!)}

授权读写健康数据

 func authorizeHealthKit(completed: @escaping ((_ isSuccess: Bool)->Void)) {let version = UIDevice.current.systemVersion.floatValue()if version >= 8.0 {if !HKHealthStore.isHealthDataAvailable() {//                let error = NSError(domain: "com.xz.healthkit", code: 2, userInfo: [NSLocalizedDescriptionKey:"HealthKit is not available in th is Device"])completed(false)}else { // 可用// 需要读写的数据类型let writeDataTypes = dateTypeToWrite()let readDataTypes = dateTypeToRead()// 注册需要读写的数据类型，也可以在'健康'中重新修改healthStore.requestAuthorization(toShare: writeDataTypes, read: readDataTypes, completion: { (isSuccess, error) inprint("错误：", error)print("权限结果：", isSuccess)completed(isSuccess)})}}else {print("iOS 系统低于8.0")completed(false)}}// 读取 Health 数据func dateTypeToRead() -> Set<HKQuantityType>? {// 身高let heightType = HKObjectType.quantityType(forIdentifier: .height)// 体重let weightType = HKObjectType.quantityType(forIdentifier: .bodyMass)// 体温let temperatureType = HKObjectType.quantityType(forIdentifier: .bodyTemperature)// 生日let birthdayType = HKObjectType.characteristicType(forIdentifier: .dateOfBirth)// 性别let sexType = HKObjectType.characteristicType(forIdentifier: .biologicalSex)// 步数let stepCountType = HKQuantityType.quantityType(forIdentifier: .stepCount)// 距离let distanceType = HKObjectType.quantityType(forIdentifier: .distanceWalkingRunning)// 活动能量let activeEnergyType = HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)return Set(arrayLiteral: heightType, temperatureType, birthdayType, sexType, weightType, stepCountType, distanceType, activeEnergyType) as? Set<HKQuantityType>}// 写 Health 数据func dateTypeToWrite() -> Set<HKQuantityType>? {// 身高let heightType = HKObjectType.quantityType(forIdentifier: .height)// 体重let weightType = HKObjectType.quantityType(forIdentifier: .bodyMass)// 体温let temperatureType = HKObjectType.quantityType(forIdentifier: .bodyTemperature)// 活动能量let activeEnergyType = HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)return Set(arrayLiteral: heightType, temperatureType, weightType, activeEnergyType) as? Set<HKQuantityType>}

修改数据

    func recordStepData(step: Int, completed: @escaping ((_ success: Bool)->Void)) {let stepType = HKQuantityType.quantityType(forIdentifier: .stepCount)if HKHealthStore.isHealthDataAvailable() {let stepQuantity = HKQuantity(unit: HKUnit.count(), doubleValue: Double(step))let stepSample = HKQuantitySample(type: stepType!, quantity: stepQuantity, start: Date(), end: Date())healthStore.save(stepSample) { (isSuccess, error) inprint("修改结果：", isSuccess)completed(isSuccess)}}else {print("写入不允许")}}

获取步数数据

    /// 获取步数func getStepCount(completion: @escaping ((_ value: Int)->Void)) {// 步数let stepType = HKObjectType.quantityType(forIdentifier: .stepCount)let timeSortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: false)let query = HKSampleQuery(sampleType: stepType!, predicate: predicateForSampelsToday(), limit: HKObjectQueryNoLimit, sortDescriptors: [timeSortDescriptor]) { (query, results, error) inif error != nil {completion(0)}else {var totalStep = 0if let results = results {for quantitySample in results {let quantitySam = quantitySample as! HKQuantitySamplelet quantity = quantitySam.quantitylet heightUnit = HKUnit.count()let usersHeight = quantity.doubleValue(for: heightUnit)totalStep += Int(usersHeight)}print("当天行走步数 =", totalStep)completion(totalStep)}}}// 执行查询healthStore.execute(query)}
