如何在swift 3中获取和更新Healthkit的高度

Question

我正试图从Healthkit获取和更新高度，但没有获得swift 3的任何文档。

是否有任何方法获得高度从healthKit也更新高度在healthKit?

Answer 1

创建healthkit实例

let healthKitStore:HKHealthStore = HKHealthStore()

请求许可

func requestPermissions(completion: @escaping ((_ success:Bool, _ error:Error?) -> Void)){
    let healthKitTypesToRead : Set<HKSampleType> = [
        HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.height)!,
        HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMass)!,
    ]
    let healthKitTypesToWrite: Set<HKSampleType> = [
        HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.height)!,
        HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMass)!,
    ]
    if !HKHealthStore.isHealthDataAvailable() {
        print("Error: HealthKit is not available in this Device")
        completion(false, error)
        return
    }
    healthKitStore.requestAuthorization(toShare: healthKitTypesToWrite, read: healthKitTypesToRead) { (success, error) -> Void in
        completion(success,error )
    }
}

阅读高度

let heightType = HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.height)!
let query = HKSampleQuery(sampleType: heightType, predicate: nil, limit: 1, sortDescriptors: nil) { (query, results, error) in
    if let result = results?.first as? HKQuantitySample{
        print("Height => (result.quantity)")
    }else{
        print("OOPS didnt get height nResults => (results), error => (error)")
    }
}
self.healthKitStore.execute(query)

写作高度

let height = YOUR_HEIGHT
if let type = HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.height) {
    let date = Date()
    let quantity = HKQuantity(unit: HKUnit.inch(), doubleValue: height!)
    let sample = HKQuantitySample(type: type, quantity: quantity, start: date, end: date)
    self.healthKitStore.save(sample, withCompletion: { (success, error) in
        print("Saved (success), error (error)")
    })
}

现在如果你想读取和写入重量，只需使用

HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMass)
