在 PDFView 上禁用缩放 (iOS)

Disable zooming on PDFView (iOS)

如何禁用 PDFView 的缩放功能?

我已经尝试过 here 的解决方案,但没有用。我仍然可以放大和缩小。

这是我的 PDFView:

let pdfView: PDFView = {
    let pdfView = PDFVIew()
    let urlPath = Bundle.main.path(forResource: "PdfFile", ofType: "pdf")
    let url = URL(fileURLWithPath: urlPath!)
    pdfView.document = PDFDocument(url: url)
    pdfView.autoScales = true
    pdfView.displayMode = .singlePageContinuous
    pdfView.displayDirection = .vertical
    pdfView.pageShadowsEnabled = false
    return pdfView
}()

添加以下代码行将禁用 PDFView.

的缩放
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    pdfView.minScaleFactor = pdfView.scaleFactor
    pdfView.maxScaleFactor = pdfView.scaleFactor
}
