如何在swift 3中获取和更新Healthkit的高度？

Question

我试图从Healthkit获取并更新高度，但没有获得swift 3的任何文档。

有没有办法从healthKit获取高度也更新healthKit的高度？

Answer 1

创建一个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，如果您想读取和写入重量，那么只需使用

HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.bodyMass)
