In my iOS-App I'm using a PDFView
with pdfView.usePageViewController(true, withViewOptions: nil)
.
I want to hide the PDFThumbnailView
when the user swipes to another page.
I already looked inside PDFViewDelegate
but there's no suitable function to use.
you can try adding observer for PDFViewPageChanged notification like this
// Add page changed listener
NotificationCenter.default.addObserver(
self,
selector: #selector(handlePageChange(notification:)),
name: Notification.Name.PDFViewPageChanged,
object: pdfView)
And then handle the page change event :
@objc private func handlePageChange(notification: Notification)
{
// Do your stuff here like hiding PDFThumbnailView...
}
Hope it helps
