From Data

Display a PDFDocument

navigationController?.pushViewController(readerController, animated: true)

Customizations

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
