Create a PDFDocument

let document = PDFDocument(url: documentFileURL)!
From a remote URL
let remotePDFDocumentURLPath = "http://devstreaming.apple.com/videos/wwdc/2016/201h1g4asm31ti2l9n1/201/201_internationalization_best_practices.pdf"
let remotePDFDocumentURL = URL(string: remotePDFDocumentURLPath)!
let document = PDFDocument(url: documentRemoteURL)!
From Data
let document = PDFDocument(fileData: fileData, fileName: "Sample PDF")!

Display a PDFDocument

let readerController = PDFViewController.createNew(with: document)
navigationController?.pushViewController(readerController, animated: true)


Controller Title

PDFViewController.createNew(with: document, title: "Favorite Cupcakes")

Background Color

controller.backgroundColor = .white

Action Button Image and Action

Available Action Styles
/// Action button style
public enum ActionStyle {
    /// Brings up a print modal allowing user to print current PDF
    case print

    /// Brings up an activity sheet to share or open PDF in another app
    case activitySheet

    /// Performs a custom action
    case customAction((Void) -> ())
let actionButtonImage = UIImage(named: "cupcakeActionButtonImage")
PDFViewController.createNew(with: document, title: "Favorite Cupcakes", actionButtonImage: actionButtonImage, actionStyle: .activitySheet)

Override the default backbutton

/// Create a button to override the default behavior of the backbutton.  In the below example we create a cancel button which will call our myCancelFunc method on tap.
let myBackButton = UIBarButtonItem(title: "Cancel", style: .done, target: self, action:  #selector(self.myCancelFunc(_:)))
/// Provide your button to createNew using the backButton parameter.  The PDFViewController will then use your button instead of the default backbutton.
PDFViewController.createNew(with: document, title: "Favorite Cupcakes", backButton: myBackButton)

Do not load the thumbnails in the controller

let controller = PDFViewController.createNew(with: document, isThumbnailsEnabled: false)

Change scroll direction of the pages from left to right to top to bottom

controller.scrollDirection = .vertical
