HealthKit是iOS8的特性，用來提供存儲和獲取用戶健康數(shù)據(jù)

1。獲取HealthKit的授權(quán),在Targets－Capabilities打開HealthKit的開關(guān)

• 如果是app支持iOS8以下或者需要支持pad等不支持healthKit，需要在info。plist里刪除掉healthKit的選項，或者會被蘋果拒
  并請求這些應(yīng)用裝不上App
  如下圖

最后的配置圖下

2。指定HealthKit的數(shù)據(jù)類型，并授權(quán)

HealthKit的數(shù)據(jù)類型都是HKObjectType的子類，提供了5個方法用來獲取HKObjectType子類的類型，再

  public class func quantityTypeForIdentifier(identifier: String) -> HKQuantityType?
  public class func categoryTypeForIdentifier(identifier: String) -> HKCategoryType?
  public class func characteristicTypeForIdentifier(identifier: String) -> HKCharacteristicType?
  public class func correlationTypeForIdentifier(identifier: String) -> HKCorrelationType?
  public class func workoutType() -> HKWorkoutType

identifier類型可通過https://developer.apple.com/library/watchos/documentation/HealthKit/Reference/HealthKit_Constants/#//apple_ref/doc/constant_group/Body_Measurements 查看

授權(quán)代碼

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        healthStore = HKHealthStore()
        if HKHealthStore.isHealthDataAvailable() {
            self.authorizeHealthKit()
        }

    }

    func authorizeHealthKit() {

        let readType:Set<HKObjectType> = [HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)!]
        let writeType:Set<HKSampleType> = [HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)!]

        //獲取授權(quán)
        self.healthStore.requestAuthorizationToShareTypes(writeType, readTypes: readType) { (x:Bool, y:NSError?) -> Void in

        }

    }
