HKWorkoutSession 没有将应用程序放在 Apple Watch 前面 [英] HKWorkoutSession isn't keeping app at front of Apple Watch

问题描述

有人表示，运行 HKWorkoutSession 的应用程序将比其他 watchOS 2 应用程序具有特殊权限，因此当用户查看他们的 Apple Watch 时，它会转到显示正在锻炼的视图，而不是表盘.

It has been stated that an app running a HKWorkoutSession will have special privileges over other watchOS 2 apps, so when a user looks at their Apple Watch, it will go to the view showing running a workout rather than the watch face.

目前，在我的设备和模拟器上，情况并非如此.如果我开始 HKWorkoutSession，然后离开 5 分钟，然后与 Apple Watch 或 Watch Simulator 交互，它会显示表盘.

Currently, on both my device and simulator, this is not the case. If I start a HKWorkoutSession and then leave for 5 minutes and then interact with either the Apple Watch, or the Watch Simulator, it presents the watch face.

如果我然后打开我的应用程序，它似乎已被冻结，而不是终止(我认为其他应用程序会发生这种情况).当我需要在我的 query.updateHandler 中接收响应时，UI 会更新.此外，如果我将其设置为每次我的 query.updateHandler 收到新的 HKQuantitySample 时都提供触觉反馈，它就会这样做，因此应用程序必须以某种形式在后台运行.

If I then open my app, it appears to have been frozen, rather than terminated (which is what I imagine happens to other apps). As the UI will update when I need receive a response in my query.updateHandler. Also if I set it to provide haptic feedback every time my query.updateHandler receives a new HKQuantitySample it will do so, so the app must be running in the background in some form.

有没有其他人注意到这种行为，我是否做错了什么，或者期待我不应该做的事情?

Has anyone else noticed this behaviour, and am I doing anything wrong, or expecting something I shouldn't?

这是我如何开始我的 HKWorkoutSession:

Here is how I start my HKWorkoutSession:

    self.workoutSession = HKWorkoutSession(activityType: HKWorkoutActivityType.Other, locationType: HKWorkoutSessionLocationType.Indoor)

        self.healthStore.startWorkoutSession(self.workoutSession) {
            success, error in

            if error != nil {
                print("startWorkoutSession \(error)\n")
                self.printLabel.setText("startWorkoutSession \(error)")
                self.printLabel.setTextColor(UIColor.redColor())
            }

推荐答案

我们也看到了这一点，目前我们已经确保配置了打开上一个活动".

We're seeing that too, for the moment we've made sure 'opens last activity' is configured.

当 UI 处于活动状态时，我们会启动一个 dispatch_timer 以 1 秒为间隔请求和处理数据.

When the UI is active we start a dispatch_timer to request and process data in 1 second intervals.

确保您使用 NSUserProcessInfo 方法进行任何重要的处理，并在您不再活动时暂停 dispatch_timers.否则你会崩溃.

Make sure you do any significant processing using the NSUserProcessInfo method though and pause the dispatch_timers whenever you are no longer active. You'll get crashes otherwise.
