PDFView不调整大小

Question

我们给出了PDFView的静态高度和宽度。假设300 * 300

之后，我们将从远程URL加载文档并将其添加到PDFView中。方向将是垂直。

它不适应我们给出的基本尺寸，它的水平滚动和缩放也不是很好。

代码：

import UIKit
import PDFKit
class ViewController: UIViewController {

    @IBOutlet weak var pdfView: PDFView!
    override func viewDidLoad() {
        super.viewDidLoad()
        DispatchQueue.main.async{
            // Instantiate PDFDocument
            let pdfDoc = PDFDocument(url: URL(string: "http://res.cloudinary.com/didzg9k3p/image/upload/v1564484497/Kuwy/2019/07/30/KW71211144636907/KW71211144636907/zvzinxp5oqwku2kqpwv6.pdf")!)
            self.pdfView.document = pdfDoc
            self.pdfView.autoScales = true
            self.pdfView.displayDirection = .vertical
            self.pdfView.backgroundColor = .orange
            let scaleFactor = self.pdfView.scaleFactor
            self.pdfView.scaleFactor = scaleFactor
        }
        // Do any additional setup after loading the view.
    }
}

Answer 1

您能在autoScales赋值之后添加并尝试这些代码吗？pdfView.minScaleFactor = pdfView.scaleFactorForSizeToFit
