Question

我正在开发Apple watch app，我正在使用HKworkoutsession来访问心率数据样本。

在最新的watchos2 beta3发布错误中“在活动的锻炼期间，屏幕关闭时不会生成新的心率样本。”是固定的。

我的问题是我怎样才能将我的HKworkoutsession永远设置为“积极的锻炼课程”，因此我可以根据需要随时获取心率样本。

以下代码是如何开始或停止锻炼课程。

let healthStore = HKHealthStore()
healthStore.startWorkoutSession(workoutSession) {
  (result: Bool, error: NSError?) -> Void in
}

healthStore.stopWorkoutSession(workoutSession) {
  (result: Bool, error: NSError?) -> Void in
}

有HKWorkoutSessionDelegate通知其会话状态。

protocol HKWorkoutSessionDelegate : NSObjectProtocol {

func workoutSession(workoutSession: HKWorkoutSession,
  didChangeToState toState: HKWorkoutSessionState,
  fromState: HKWorkoutSessionState, date: NSDate)

func workoutSession(workoutSession: HKWorkoutSession,
  didFailWithError error: NSError)
}

ObjC版

HKWorkoutSession *workoutSession = [[HKWorkoutSession alloc] initWithActivityType:HKWorkoutActivityTypeRunning locationType:HKWorkoutSessionLocationTypeOutdoor];
workoutSession.delegate = self;

HKHealthStore *healthStore = [HKHealthStore new];
[healthStore startWorkoutSession:workoutSession];

[healthStore stopWorkoutSession:workoutSession];

HKWrokoutSessionDelegate

- (void)workoutSession:(HKWorkoutSession *)workoutSession
  didChangeToState:(HKWorkoutSessionState)toState
         fromState:(HKWorkoutSessionState)fromState
              date:(NSDate *)date;

- (void)workoutSession:(HKWorkoutSession *)workoutSession didFailWithError:(NSError *)error;

警告：使用最新版本更改方法名称，观看OS 2 beta 5。

stopWorkoutSession已更改为endWorkoutSession。

如何使HKworkoutsession始终是一个积极的锻炼课程
