Ios 如何使用SWIFT显示多文档PDF页面的单个页面

我想为选定的PDF文件显示一个页面，即使PDF有多个页面

因此，根据所选页码，仅显示单个PDF页面

我在写这段代码：

    let path = NSURL(fileURLWithPath: Bundle.main.path(forResource: "PDFName", ofType: "pdf")!)
    let request = NSURLRequest(url: path as URL)
    webView.loadRequest(request as URLRequest)

但这会显示文档的所有页面。

我只想按页码显示一页？

对于分步实施，您可以获得教程和

swift3

class ViewController:UIViewController,UIDocumentInteractionControllerDelegate

并像这样调用函数

@IBAction func btnOpenModal(_ sender: UIButton) {

  //  var button: UIButton? = (sender as? UIButton)
    let URLName: URL? = Bundle.main.url(forResource: "sample", withExtension: "pdf")
    if URLName != nil {
        // Initialize Document Interaction Controller
        let  documentInteractionController: UIDocumentInteractionController = UIDocumentInteractionController(url: URLName!)
        // Configure Document Interaction Controller
        documentInteractionController.delegate = self
        // Present Open In Menu
        documentInteractionController.presentOpenInMenu(from: sender .frame, in: self.view, animated: true)
    }
}

func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {

    return self
}

将UIDocumentInteractiveViewController用于您的概念我查找了这个，但没有找到解决方案。有没有一个例子或解释可以帮助我这么做。我正在处理UIPageViewController应用程序，我想添加一个PDF文件，以便所有页面都显示在一个单独的页面中。谢谢，谢谢。现在您可以显示第4页，例如PDF文件的独立ViewControllero包含20页？谢谢。你的回答帮助我完成了这个项目，效果很好。

@IBAction func btnOpenModal(_ sender: UIButton) {

  //  var button: UIButton? = (sender as? UIButton)
    let URLName: URL? = Bundle.main.url(forResource: "sample", withExtension: "pdf")
    if URLName != nil {
        // Initialize Document Interaction Controller
        let  documentInteractionController: UIDocumentInteractionController = UIDocumentInteractionController(url: URLName!)
        // Configure Document Interaction Controller
        documentInteractionController.delegate = self
        // Present Open In Menu
        documentInteractionController.presentOpenInMenu(from: sender .frame, in: self.view, animated: true)
    }
}

func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {

    return self
}
