我可以从Apple Watch的Backgroun上检测到锻炼，但是如何检测锻炼完成？

Question

我可以检测到Apple Watch的BackGroun锻炼，

let workoutevent =  HKObjectType.workoutType()

 if store.authorizationStatus(for: workoutevent) != HKAuthorizationStatus.notDetermined {
            store.enableBackgroundDelivery(for: workoutevent, frequency: .immediate, withCompletion: { (worked, error) in
                print(worked)
                print(error)
                print("workoutevent enableBackgroundDelivery")
                guard worked else {
                    self.logger.error("Unable to set up background delivery from HealthKit: \(error!.localizedDescription)")
                    print("workoutevent unable to set up background ")
                    fatalError()
                }
                if error != nil {
                    print("workoutevent error is ")
                    print(error)
                }
            })


            backgroundObserver3 =
            HKObserverQuery(sampleType: workoutevent,
                            predicate: nil,
                            updateHandler: processUpdate3(query:completionHandler3:error:))
            if let queryworkout = backgroundObserver3 {
                print("Starting  workoutevent333 the background observer query.\(queryworkout)")
                store.execute(queryworkout)
            }

        }else{
            print("not determined....")
        }

每当我在Apple Watch上锻炼时， 都有以下代码 ProcessUpdate3 很好， 但是我需要知道的是用户完成锻炼时。 我该如何检测？

func processUpdate3(query: HKObserverQuery,
                       completionHandler3: @escaping () -> Void,
                       error: Error?) {
        print("come here when work out started ")

............. }

我在您的代码中看不到它。但是在某个地方，您必须有一个hkworkoutsessessessessessessessessessessessession。我的应用程序已设置为跟踪运行，我将会话配置为“这样”。

    let configuration = HKWorkoutConfiguration()
    configuration.activityType = .running

    do {
        // HKWorkoutSession is set up here.
        session = try HKWorkoutSession(healthStore: healthStore, configuration: configuration)
        workoutBuilder = session.associatedWorkoutBuilder()
    } catch {
        // handle errors
    }

当用户点击结束锻炼按钮时，我调用session.end（），
