问题描述
已经说过，运行HKWorkoutSession的应用程序将具有其他watchOS 2应用程序的特殊特权，因此，当用户查看其Apple Watch时，它将转到显示正在运行锻炼而不是表盘的视图.
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.
当前，在我的设备和模拟器上均不是这种情况.如果我启动HKWorkoutSession然后离开5分钟，然后与Apple Watch或Watch Simulator交互，它将显示表盘.
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.
如果我随后打开我的应用程序，则它似乎已冻结，而不是终止(这是我想象的其他应用程序发生的情况).因为UI将在我需要在query.updateHandler中接收响应时更新.另外，如果我将其设置为每次query.updateHandler接收到新的HKQuantitySample时都会提供触觉反馈，则它将这样做，因此该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.
还有其他人注意到这种行为吗?我做错了什么吗?还是期待某些我不应该做的事情?
Has anyone else noticed this behaviour, and am I doing anything wrong, or expecting something I shouldn't?
这是我开始HKWorkoutSession的方式:
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，我们已经确保已配置打开上一个活动".
We're seeing that too, for the moment we've made sure 'opens last activity' is configured.
当用户界面处于活动状态时，我们启动dispatch_timer，以每隔1秒的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.
但是请确保使用NSUserProcessInfo方法进行任何重要的处理，并在不再活动时暂停一下dispatch_timers.否则，您将崩溃.
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do any significant processing using the NSUserProcessInfo method though and pause the dispatch_timers whenever you are no longer active.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.
