I am trying to run codes about PDFPageOverlayViewProvider, but the codes are not working. I cannot see what I wrote or annotate. Anyone know how can I solve and make this code working?
func pdfView(_ view: PDFView, overlayViewFor page: PDFPage) -> UIView? {
var resultView: PKCanvasView? = nil
if let overlayView = pageToViewMapping[page] {
resultView = (overlayView as! PKCanvasView)
} else {
let canvasView = PKCanvasView(frame: .zero)
canvasView.drawingPolicy = .anyInput
canvasView.tool = PKInkingTool(.pen, color: .yellow, width: 20)
canvasView.backgroundColor = .clear
pageToViewMapping[page] = canvasView
resultView = canvasView
}
let page = page as! WatermarkPage
if let drawing = page.drawing {
resultView?.drawing = drawing
}
return resultView
}
func pdfView(_ pdfView: PDFView, willEndDisplayingOverlayView overlayView: UIView, for page: PDFPage) {
let overlayView = overlayView as! PKCanvasView
let page = page as! WatermarkPage
page.drawing = overlayView.drawing
pageToViewMapping.removeValue(forKey: page)
}
