Swift HealthKit简单使用

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()
    }
    
    
}
