WatchOS：每当启动第二个应用程序（如 NRC 或 Runtastic）时，HKWorkoutSession 就会结束

Question

我正在测试 Apple 的 SpeedySloth 演示应用程序：https://developer.apple.com/documentation/healthkit/workouts_and_activity_rings/speedysloth_creating_a_workout

好吧，到此为止，每当第二个应用程序启动时：

// MARK: - HKWorkoutSessionDelegate
extension WorkoutManager: HKWorkoutSessionDelegate {
    func workoutSession(_ workoutSession: HKWorkoutSession, didChangeTo toState: HKWorkoutSessionState,
                        from fromState: HKWorkoutSessionState, date: Date) {
        // Wait for the session to transition states before ending the builder.
        /// - Tag: SaveWorkout
        if toState == .ended {
            print("The workout has now ended.")
            builder.endCollection(withEnd: Date()) { (success, error) in
                self.builder.finishWorkout { (workout, error) in
                    // Optionally display a workout summary to the user.
                    self.resetWorkout()
                }
            }
        }
    }

当我在 Nike 运行 Club 中按下“开始”按钮时，使用 toState = .ended 直接调用委托。我假设，一次只能进行一种锻炼，但我可以将 Adidas 运行与 NRC 一起使用，因此，它一定是可行的。

Answer 1

HKWorkoutSession 的文档指出一次只能运行。

Apple Watch runs one workout session at a time. If a second workout starts while your workout is running, your HKWorkoutSessionDelegate object receives an HKError.Code.errorAnotherWorkoutSessionStarted error, and your session ends.

见https://developer.apple.com/documentation/healthkit/hkworkoutsession

在 Apple Watch 推出之前，有几个应用程序允许用户使用 CoreMotion API 测量运行或步行会话。我怀疑如果锻炼会话已经运行ning.

，你提到的其中一个应用程序可能会退回到这个
