Overview

Spatian span memory step.

This step type is used to present the interactive spatial span memory activity. You are not supposed to use this step on its own.

Discussion

This method is called when there is a need to validate the step’s parameters, which is typically the case when adding a step to an ORKStepViewController object, and when presenting the step view controller.

Subclasses should override this method to provide validation of their additional properties, and must call super.
