如何使用PDFKit iOS 11创建水平滚动PDF视图

Question

无法在ios 10中创建水平滚动PDF视图。 在iOS 11中这可能吗？使用PDFKit - PDFView？

Answer 1

您可以这样做：

//configure the pdfView or use it from an outlet in Storyboard
let pdfView = PDFView(frame: self.view.bounds)
let url = Bundle.main.url(forResource: "pdfFile", withExtension: "pdf")
pdfView.document = PDFDocument(url: url!)
//the important setting
pdfView.displayDirection = .horizontal
pdfView.usePageViewController(true, withViewOptions: nil)
//add to subview if you don't use an outlet
self.view.addSubview(pdfView)

Answer 2

这对我有用：

        if let path = Bundle.main.path(forResource: "myfile", ofType: "pdf") {
            let url = URL(fileURLWithPath: path)
            if let pdfDocument = PDFDocument(url: url) {
                pdfView.autoScales = true
                pdfView.displayMode = .singlePage
                pdfView.displayDirection = .horizontal
                pdfView.usePageViewController(true, withViewOptions: [UIPageViewControllerOptionInterPageSpacingKey: 5])
                pdfView.document = pdfDocument    
            }
        }
