ORKTaskResult Class Reference

Inherits from	ORKCollectionResult : ORKResult : NSObject
Conforms to	ORKTaskResultSource
Declared in	ORKCollectionResult.h

An ORKTaskResult object is a collection result that contains all the step results generated from one run of a task or ordered task (that is, ORKTask or ORKOrderedTask) in a task view controller.

A task result is typically generated by the framework as the task proceeds. When the task completes, it may be appropriate to serialize it for transmission to a server, or to immediately perform analysis on it.

The results property of the ORKCollectionResult object contains the step results for the task.

`– initWithTaskIdentifier:taskRunUUID:outputDirectory:`

Returns an intialized task result using the specified identifiers and directory.

- (instancetype)initWithTaskIdentifier:(NSString *)identifier taskRunUUID:(NSUUID *)taskRunUUID outputDirectory:(nullable NSURL *)outputDirectory

Parameters

`identifier`	The identifier of the task that produced this result.
`taskRunUUID`	The UUID of the run of the task that produced this result.
`outputDirectory`	The directory in which any files referenced by results can be found.

Return Value

An initialized task result.

Declared In

ORKCollectionResult.h

`taskRunUUID`

A unique identifier (UUID) for the presentation of the task that generated the result.

@property (nonatomic, copy, readonly) NSUUID *taskRunUUID

Discussion

The unique identifier for a run of the task typically comes directly from the task view controller that was used to run the task.

Declared In

ORKCollectionResult.h

`outputDirectory`

The directory in which the generated data files were stored while the task was run.

@property (nonatomic, copy, readonly, nullable) NSURL *outputDirectory

Discussion

The directory comes directly from the task view controller that was used to run this task. Generally, when archiving the results of a task, it is useful to archive all the files found in the output directory.

The file URL also prefixes the file URLs referenced in any child ORKFileResult objects.
