The ORKSignatureStep class is used to represent collecting a signature. Typically, the consent signature is collected as a part of the consent review process.

However, since in some cases the signature is collected after displaying custom consent review steps, it is exposed to allow showing this as it’s own step.

To use a consent signature step, configure it and include it in a task. Then present the task in a task view controller.

The result of this step is an ORKSignatureResult which will include both the UIImage and the path used to draw the image.
