 The below code snippet illustrates supressing the signature modal view and using a UI implemented in the app in its place. In this illustration, it is assumed that the signature is produced in the form of an image stream when the user completes drawing the signature in the custom dialog. When the PDF viewer is tapped, the created signature is added as a stamp annotation.
