I am using PDFKit to render PDF & form filling. I saw the video on WWDC 2017 for PDFkit. Using annotation is explained clearly there. But I want to use PDFAnnotationWidgetSubtype signature in my application. I am not able to get the expected output. I am attaching the code :
func addSignature() {
let bounds = CGRect(x: 100, y: 100, width: 300, height: 50)
let annotation = PDFAnnotation(bounds: bounds, forType: PDFAnnotationSubtype.widget, withProperties: nil)
annotation.backgroundColor = UIColor.blue
annotation.color = UIColor.darkGray
annotation.fieldName = "signature"
annotation.widgetFieldType = .signature
annotation.caption = "WORK"
annotation.shouldDisplay = true
annotation.shouldPrint = true
annotation.widgetControlType = .unknownControl
let border = PDFBorder() border.lineWidth = 2.0
annotation.border = border
print("Appareance Stream \(annotation.hasAppearanceStream)")
pdfView.document?.page(at: 0)?.addAnnotation(annotation)
}
This code just makes a box of given dimensions and do not detect apple pencil/hand touch gesture to take signature. Do let me know if I am missing anything here.
