我用的类，本篇博客只是入门，所有的添加步数或者修改信息这里都没做，以后如果有时间我会补上
plist文件设置
Privacy - Health Update Usage Description Privacy - Health Share Usage Description
有人配置了也报错，需要配置文件写英文，不能用中文，我改成英文就好了，
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: HKQuantityTypeIdentifierActiveEnergyBurned, HKQuantityTypeIdentifierDistanceWalkingRunning, HKWorkoutTypeIdentifier, HKQuantityTypeIdentifierStepCount, HKQuantityTypeIdentifierBodyMassIndex'
HealthKit需要先判断权限，如果权限通过了，才可以获取其他的，所有的代码都需要在authorizeHealthKit方法成功之后，才可以调用，HealthKit并不是说我获取一个权限就好了，所有的步数，获取体重都是单独的，所有的权限都需要单独获取
- 首先，项目开启HealthKit
判断和申请权限，manager的代码：
import HealthKit
class HealthManager: NSObject {
let healthKitStore:HKHealthStore = HKHealthStore()
//这里是获取权限
func authorizeHealthKit(completion: ((_ success:Bool, _ error:NSError!) -> Void)!)
{
// 需要获取的数据 出生年月 血型 性别 体重 身高
let healthKitTypesToRead = NSSet(array:[
HKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier.dateOfBirth) as Any ,
HKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier.bloodType) as Any,
HKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier.biologicalSex) as Any,
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMass) as Any,
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.height) as Any,
HKObjectType.workoutType()
])
//需要写入的数据
let healthKitTypesToWrite = NSSet(array:[
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMassIndex) as Any,
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.activeEnergyBurned) as Any,
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning) as Any,
HKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount) as Any,
HKQuantityType.workoutType()
])
// 健康是否可以使用
if !HKHealthStore.isHealthDataAvailable()
{
let error = NSError(domain: "com.raywenderlich.tutorials.healthkit", code: 2, userInfo: [NSLocalizedDescriptionKey:"HealthKit is not available in this Device"])
if( completion != nil )
{
completion(false, error)
}
return;
}
// 授权
healthKitStore.requestAuthorization(toShare: healthKitTypesToWrite as? Set<HKSampleType>, read: healthKitTypesToRead as? Set<HKObjectType>) { (success, error) in
if( completion != nil )
{
completion(success, error as NSError?)
}
};
}
//获取身高
func getHeight(completion: ((_ success:Bool,_ height:Double, _ error:NSError!) -> Void)!){
//出事话一个HKSampleSortIdentifierEndDate为key的降序，这样会得到一个用户存储在health sore中的最新的的体重取样
let sort:NSSortDescriptor = NSSortDescriptor.init(key: HKSampleSortIdentifierEndDate, ascending: false)
var query = HKSampleQuery.init(sampleType: HKSampleType.quantityType(forIdentifier: .height)!, predicate: nil, limit: 1, sortDescriptors: [sort], resultsHandler: { (query, results, error) in
if(results?.count ?? 0 > 0){
let sameple = results?[0] as! HKQuantitySample
let height = sameple.quantity.doubleValue(for: HKUnit.meter())
completion(true,height,nil)
}else{
completion(false,0,error as NSError?)
}
})
healthKitStore.execute(query)
}
//获取步数
func getStepCount(){
//出话一个HKSampleSortIdentifierEndDate为key的降序，这样会得到一个用户存储在health sore中的最新的数据取样
let sort:NSSortDescriptor = NSSortDescriptor.init(key: HKSampleSortIdentifierEndDate, ascending: false)
// let predicate = HKQuery.predicateForSamples(withStart: nil, end: NSDate.init() as Date, options: .strictStartDate)
var query = HKSampleQuery.init(sampleType: HKSampleType.quantityType(forIdentifier: .stepCount)!, predicate: nil, limit: HKObjectQueryNoLimit, sortDescriptors: [sort], resultsHandler: { (query, results, error) in
print("-----------(results)")
for sameple in results ?? []{
let model = sameple as! HKQuantitySample
print("----------- (model.startDate) ( model.startDate) ( model.quantity)")
}
})
healthKitStore.execute(query)
}
}
ViewController代码
class ViewController: UIViewController {
let manager:HealthManager = HealthManager.init()
override func viewDidLoad() {
super.viewDidLoad()
manager.authorizeHealthKit { (success, error) in
if(success){
self.getInfo(); //获取数据
self.getHeight();
}else{
print("--------------------(String(describing: error))")
}
}
}
func getInfo(){
let healthKitStore = HKHealthStore()
do {
let unwrappedBiologicalSex = try healthKitStore.biologicalSex()
switch unwrappedBiologicalSex.biologicalSex {
case .notSet:
print("性别：没有设置")
break
case .female:
print("性别：女")
break
case .male:
print("性别：男")
break
default:
print("性别：其他")
break
}
let birthDate = try healthKitStore.dateOfBirthComponents()
print("出生日期：(birthDate.year!)年(birthDate.month!)月(birthDate.day!)日")
} catch let error {
print("没有权限获取该数据(error)")
}
}
func getHeight(){
// manager.getHeight { (success, height, error) in
// print("这里是身高：(height)")
// }
manager.getStepCount()
}
}
