ORKAccelerometerRecorderConfiguration Class Reference
| Inherits from | ORKRecorderConfiguration : NSObject |
|---|---|
| Declared in | ORKRecorder.h |
The ORKAccelerometerRecorderConfiguration subclass configures
the collection of accelerometer data during an active step.
Accelerometer data is serialized to JSON and returned as an ORKFileResult object.
For details on the format, see CMAccelerometerData+ORKJSONDictionary.
To use a recorder, include its configuration in the recorderConfigurations property
of an ORKActiveStep object, include that step in a task, and present it with
a task view controller.
