PSPDFSignatureViewController


@interface PSPDFSignatureViewController
    : PSPDFBaseViewController <PSPDFStyleable>

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.

  • Lines (arrays of boxed PSPDFDrawingPoints) of the drawView.

    Note

    Lines are in view coordinate space. To save them into PDF, first convert them to PDF coordinates

    See

    PSPDFConvertViewLinesToPDFLines for converting the points.

    Declaration

    Objective-C

    @property (readonly, nonatomic) NSArray<NSArray<NSValue *> *> *_Nonnull lines;

    Swift

    var lines: [[NSValue]] { get }

  • Enable natural drawing. Defaults to NO. Usually set via PSPDFConfiguration.naturalSignatureDrawingEnabled.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) BOOL naturalDrawingEnabled;

    Swift

    var naturalDrawingEnabled: Bool { get set }

  • Color options for the color picker (limit this to about 3 UIColor instances). Defaults to black, blue and red.

    Declaration

    Objective-C

    @property (readwrite, copy, nonatomic) NSArray<UIColor *> *_Nonnull menuColors;

    Swift

    var menuColors: [UIColor] { get set }

  • Signature controller delegate.

    Declaration

    Objective-C

    @property (readwrite, nonatomic)
    id<PSPDFSignatureViewControllerDelegate> _Nullable delegate;

    Swift

    @IBOutlet weak var delegate: PSPDFSignatureViewControllerDelegate? { get set }

  • Defines if a signature should be saved. Defaults to PSPDFSignatureSavingStrategySaveIfSelected. Usually set via PSPDFConfiguration.signatureSavingStrategy. Shows a checkbox, when set to PSPDFSignatureSavingStrategySaveIfSelected.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
    PSPDFSignatureSavingStrategy savingStrategy;

    Swift

    var savingStrategy: PSPDFSignatureSavingStrategy { get set }

  • Defines if the certificate picker button should be shown. Defaults to PSPDFSignatureCertificateSelectionModeIfAvailable. Usually set via PSPDFConfiguration.signatureCertificateSelectionMode.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
    PSPDFSignatureCertificateSelectionMode certificateSelectionMode;

    Swift

    var certificateSelectionMode: PSPDFSignatureCertificateSelectionMode { get set }

  • Internally used draw view. Use lines as a shortcut to get the drawn signature lines.

    Use the draw view to access additional drawing data, including biometric values.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFDrawView *_Nonnull drawView;

    Swift

    var drawView: PSPDFDrawView { get }

  • Signer used for digitally signing. If this is set, a digital signature will be created instead of an ink signature.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) PSPDFSigner *signer;

    Swift

    var signer: PSPDFSigner? { get }

  • Deprecated

    Deprecated in PSPDFKit 8.3 for iOS. A landscape ratio for drawing is now always used by default. Not using a landscape aspect ratio will cause drawing to be cut off on rotation or on app size changes.

    Keeps the drawing area aspect ratio regardless of the interface orientation. Setting this to NO might produce unexpected results if the view bounds change. Defaults to YES.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) BOOL keepLandscapeAspectRatio;

    Swift

    var keepLandscapeAspectRatio: Bool { get set }

SubclassingHooks
