Hi all,
I'm trying to zoom in on an image that is updated every second.
I have tried many ways (scroll view above all) but I like none very much.
the most interesting way was to create a PDF with this code:
self.pdfView = PDFView(frame: self.view.bounds)
self.pdfView.displayDirection = .vertical
self.pdfView.displayMode = .singlePage
self.pdfView.backgroundColor = UIColor.white
if let pdfPage = PDFPage(image: self.image) {
let pdfDoc = PDFDocument()
pdfDoc.insert(pdfPage, at: 0)
self.pdfView.document = pdfDoc
self.pdfView.autoScales = true
self.pdfView.minScaleFactor = self.pdfView.scaleFactorForSizeToFit
}
self.view.addSubview(self.pdfView)
I really like the zoom this way, but I have no ability to update the PDF image.
is this possible?
Or do you have other easy ways to zoom?
Thank you.
