ORKInstructionStep Class Reference

Inherits from ORKStep : NSObject
Declared in ORKInstructionStep.h

An ORKInstructionStep object gives the participant instructions for a task.

You can use instruction steps to present various types of content during a task, such as introductory content, instructions in the middle of a task, or a final message at the completion of a task.

To indicate the completion of a task, consider using an ORKCompletionStep object instead.

  footnote

Additional text to display for the step in a localized string at the bottom of the view.

@property (nonatomic, copy, nullable) NSString *footnote

Discussion

The footnote is displayed in a smaller font below the continue button. It is intended to be used in order to include disclaimer, copyright, etc. that is important to display in the step but should not distract from the main purpose of the step.

  auxiliaryImage

An image that provides visual context for the instruction that will allow for showing a two-part composite image where the image is tinted and the auxiliaryImage is shown with light grey.

@property (nonatomic, copy, nullable) UIImage *auxiliaryImage

Discussion

The image is displayed with the same frame as the image so both the auxiliaryImage and image should have transparently to allow for overlay.
