Hide indicator scroll in PDFKit

This is my PDFView config. I want to show PDF viewer with horizontal scroll, show single page.

But PDFView show the scroll indicator and it is not correct. I want to hide scroll indicator. My question is how to hide it or how to make its scroll position correct?

Horizontal scroll indicator visible at bottom of screen 
pdfView.autoScales = true
pdfView.displaysPageBreaks = true
pdfView.displayMode = .singlePageContinuous
pdfView.usePageViewController(true)
pdfView.displayDirection = .horizontal
pdfView.minScaleFactor = 1
pdfView.document = pdfDocument
Solution

  • Since PDFview is not giving access to its scrolling elements, the trick of accessing subviews of pdfview may work for you.

    Chain of subviews when printed on console looks like:

    (lldb) po pdfView.subviews
▿ 1 element
    - 0 : <_UIPageViewControllerContentView: 0x7fec7411d9f0; frame = (0 0; 414 808); clipsToBounds = YES; opaque = NO; autoresize = W+H; layer = <CALayer: 0x600001b33720>>

(lldb) po pdfView.subviews.first?.subviews.first
▿ Optional<UIView>
  - some : <_UIQueuingScrollView: 0x7fec7483aa00; frame = (0 0; 414 736); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x6000015153e0>; layer = <CALayer: 0x600001b33740>; contentOffset: {414, 0}; contentSize: {1242, 736}; adjustedContentInset: {0, 0, 0, 0}>

(lldb)

    So based on this, I have tested below code and it worked at my end. Try with code:

        let pdfScrollView = pdfView.subviews.first?.subviews.first as? UIScrollView
    pdfScrollView?.showsHorizontalScrollIndicator = false  // if pdf view scroll direction is horizontal
    pdfScrollView?.showsVerticalScrollIndicator = false // if pdf view scroll direction is vertical

    Edit:

    The view's hierarchy is been updated and scrollView is not at the first place Please refer answer from @Deepansh for getting scrollView object: https://stackoverflow.com/a/77080309/2677551
