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
Lines (arrays of boxed PSPDFPoints) 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 }
naturalDrawingEnabled
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 }
menuColors
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: [NSColor] { get set }


                        
                        
                        delegate

Signature controller delegate.

Declaration

Objective-C

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

Swift

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

savingStrategy
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 }
certificateSelectionMode
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 }

Styling

keepLandscapeAspectRatio
Keeps the drawing area aspect ration regardless of the interface orientation. Setting this to NO might produce unexpected results if the view bounds change. Defaults to YES, except if the view is presented inside a form sheet on iPad.
Declaration
Objective-C

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

var keepLandscapeAspectRatio: Bool { get set }
