Hi,
we have an application that observes PDFViewVisiblePagesChanged and PDFViewPageChanged notifications for detecting the scroll state of a PDFView
NotificationCenter.default.addObserver(self, selector: #selector(handleOnScroll), name: Notification.Name.PDFViewVisiblePagesChanged, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(handleOnScroll), name: Notification.Name.PDFViewPageChanged, object: nil)
With iOS14 this worked like a charm, the notification gets triggered immediately when the user starts scrolling the pdf.
In iOS16 we have issues, it seems that the notifications get triggered/send only after the scrolling has been completed/stopped.
Can anybody confirm this?
Has anybody a solution how we can detect a scrolling PDFView using a different method? Background: While the PDF is scrolling other elements of the UI need to be disabled.
Thanks
Jürgen
