How do I set the top anchor point of a pdf in PDFKit? I am looking for the same behavior as iOS files app. When I tap the pdf I want the bars on top and bottom to slide away and the pdf to be full screen. The problem I am having is that the top of the pdf is unreadable do to the Dynamic Island. I want the top of the pdf to be where a navigation bar would end.
Here is the entire code file that I am using to render the pdf. I have modified some of the names but otherwise it’s the same.
class PDFViewController: UIViewController {
let document: PDFDocument?
var pdfView: PDFView!
init(document: PDFDocument?) {
self.document = document
super.init(nibName: nil, bundle: nil)
}
override func loadView() {
let view = PDFView()
self.view = view
self.pdfView = view
view.document = document
view.displayDirection = .vertical
view.autoScales = true
}
required init?(coder: NSCoder) {
document = nil
super.init(coder: coder)
return nil
}
override func viewDidLayoutSubviews() {
let bounds = view.bounds
if let document {
if let page = document.page(at: 0) {
let pageBounds = page.bounds(for: .mediaBox)
if bounds.width > 0 && pageBounds.width > 0 {
let scaleFactor = bounds.width / pageBounds.width
let subtractionFactor = scaleFactor * 0.0125 // 0.008 for 6.1" iPhone
pdfView.minScaleFactor = scaleFactor - subtractionFactor
}
}
}
}
}
struct SheetView: UIViewControllerRepresentable {
typealias UIViewControllerType = PDFViewController
let document: PDFDocument?
let file: AsyncFile?
func makeUIViewController(context: Context) -> PDFViewController {
if let file, document == nil {
file.invalidate()
}
let controller = PDFViewController(document: document)
return controller
}
func updateUIViewController(_ uiViewController: PDFViewController, context: Context) {
}
}
