PSPDFSignatureViewController

Objective-C


@interface PSPDFSignatureViewController
    : PSPDFBaseViewController <PSPDFStyleable, PSPDFOverridable>

Swift

class SignatureViewController : PDFBaseViewController, Styleable, Overridable

The signature view controller can be used to create ink signatures to add to a document.

These signatures optionally can be used to create a digital signature with a certificate.

This class requires that your license includes the Annotations feature and was originally purchased before the introduction of the Electronic Signatures component in March 2021. If you did not purchase your license before this time, then you should use SignatureCreationViewController from Electronic Signatures instead.
