未打开HealthKit权限

Question

我的应用程序没有打开Healthkit权限屏幕，用户可以在该屏幕上允许访问HealthKit。我在手表上看到我的应用程序“想要访问您的健康数据”的屏幕。但手机只是简单地移动到应用程序启动屏幕，然后是第一页，而不是调出设置。没有错误。该应用程序的编码如下，以请求授权。有什么想法吗？

在电话AppDelegate中：

import UIKit
import WatchConnectivity
import HealthKit


@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, WCSessionDelegate {

var window: UIWindow?
let healthStore = HKHealthStore()


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    WatchSessionManager.sharedManager.startSession()


    return true
}


// authorization from watch
func applicationShouldRequestHealthAuthorization(application: UIApplication) {

    let healthStore = HKHealthStore()

    let quantityType = HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)

    let calorieQuantityType = HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)

    let dataTypesToRead = NSSet(objects: HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!, HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierActiveEnergyBurned)!)
   healthStore.requestAuthorizationToShareTypes(nil, readTypes: dataTypesToRead as! Set<HKObjectType>, completion: { (success, error) in
        if success {
        } else {
            print(error!.description)
        }
        })

    healthStore.handleAuthorizationForExtensionWithCompletion { success, error in

    }
}

    let healthKitStore:HKHealthStore = HKHealthStore()

        func authorizeHealthKit(completion: ((_ success:Bool, _ error:NSError?) -> Void)!)
        {   
            //check app is running on iPhone not other devices(iPad does not have health app)
            if !HKHealthStore.isHealthDataAvailable()
            {
                let error = NSError(domain: "DomainName.HealthKitTest", code: 2, userInfo: [NSLocalizedDescriptionKey:"HealthKit is not available in this Device"])
                if completion != nil
                {
                    completion(false, error)
                }
                return;
            }

            healthKitStore.requestAuthorization(toShare: healthKitTypeToWrite() as? Set<HKSampleType>, read: nil) { (success, error) -> Void in

                if completion != nil
                {
                    print("Success: \(success)")
                    print("Error: \(error)")
                    completion?(success, error as NSError?)
                }
            }
        }

        func healthKitTypeToWrite() -> NSSet {
            let typesToWrite = NSSet(objects: HKQuantityType.quantityType(forIdentifier: .dietaryFatTotal),
                                              HKQuantityType.quantityType(forIdentifier: .dietaryFatSaturated),
                                              HKQuantityType.quantityType(forIdentifier: .dietaryCarbohydrates),
                                              HKQuantityType.quantityType(forIdentifier: .dietarySugar),
                                              HKQuantityType.quantityType(forIdentifier: .dietaryProtein),
                                              HKQuantityType.quantityType(forIdentifier: .dietarySodium))
            return typesToWrite
        }

一定要在你的info.plist和描述中添加'NSHealthUpdateUsageDescription‘，说明为什么你需要访问你的应用程序。

希望这能对你有所帮助。

在我的info.plist中添加NSHealthUpdateUsageDescription解决了这个问题。
