Adding a back button without using a nav controller? about ios-pdf-reader HOT 3 OPEN

Its possible, the app should detect when its being presented in a modal, and if so, it should have some sort of close button to dismiss. Great idea!

from ios-pdf-reader.

I found a solution for this:

// Create a back button programmatically - the goBackTapped function just dismiss the viewcontroller.
let myBackButton = UIBarButtonItem(title: "Cancel", style: .done, target: self, action: #selector(self.goBackTapped(_:)))

//create the document
let document = PDFDocument(fileData: pdf_data, fileName: "contract_pdf")

//load the PDFViewController
let readerController = PDFViewController.createNew(with: document!, title: "Contract", backButton: myBackButton)

//Create a UINaviagationController and pass the readerController you just created
let targetNavigationController = UINavigationController(rootViewController: readerController)

// Present the NavitationController
self.present(targetNavigationController, animated: true, completion: nil)

Hope this help :)
