workoutWithActivityType:startDate:endDate:workoutEvents:totalEnergyBurned:totalDistance:totalSwimmingStrokeCount:device:metadata:

If the optional total parameters are specified, matching samples that add up to the calculated total quantities should be associated with this workout using addSamples:toWorkout:completion: in HKHealthStore.

Parameters:

workoutActivityType - The activity type of the workout

startDate - The point in time that the workout was started

endDate - The point in time that the workout was ended

workoutEvents - An array of HKWorkoutEvents. The workout's duration is derived from these events. (Optional)

totalEnergyBurned - The amount of energy that was burned during the workout. (Optional)

totalDistance - The total distance that was traveled during the workout. (Optional)

totalSwimmingStrokeCount - The total count of swimming strokes that was accumulated during the workout. (Optional)

device - The HKDevice associated with the workout. (Optional)

metadata - Metadata for the workout. (Optional)

duration

public double duration()

[@property] duration

The length of time that a workout was recording

The duration is derived from the start and end dates of the workout and takes into account periods that the workout was paused. Periods that the workout was paused are based off of the workoutEvents property.

init

public HKWorkout init()

Overrides:

init in class HKSample

initWithCoder

public HKWorkout initWithCoder(NSCoder coder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoder in class HKSample

_supportsSecureCoding

public boolean _supportsSecureCoding()

Description copied from interface: NSSecureCoding

This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.

Specified by:

_supportsSecureCoding in interface NSSecureCoding

Overrides:

_supportsSecureCoding in class HKSample

totalDistance

public HKQuantity totalDistance()

[@property] totalDistance

The total distance that was traveled during a workout

This metric should represent the total distance traveled during the course of the workout. It should be a quantity with a unit representing length.

totalEnergyBurned

public HKQuantity totalEnergyBurned()

[@property] totalEnergyBurned

The amount of energy that was burned during a workout

This metric should represent the total active energy burned during the course of the workout. It should be a quantity with a unit representing energy.

totalSwimmingStrokeCount

public HKQuantity totalSwimmingStrokeCount()

[@property] totalSwimmingStrokeCount

The total count of swimming strokes that was accumulated during a workout

This metric should represent the total count of swimming strokes accumulated during the course of the workout. It should be a quantity with a unit representing count.

workoutActivityType

public long workoutActivityType()

[@property] workoutActivityType

Represents the activity that the user was performing during a workout

workoutEvents

public NSArray<? extends HKWorkoutEvent> workoutEvents()

[@property] workoutEvents

An array of HKWorkoutEvents that occurred during a workout.

These events will be ordered by date in ascending order. All events must take place between the start date and end date of the workout. The first workout event should never be a resume event because it is assumed that the workout begins in a running state.

totalFlightsClimbed

public HKQuantity totalFlightsClimbed()

[@property] totalFlightsClimbed

The total count of flights climbed during a workout

This metric should represent the total count of flights accumulated during the course of the workout. It should be a quantity with a unit representing count.
