How to open files imported by UIDocumentPicker?

Question

In my app I picked files by UIDocumentPicker and put file names on a tableView . When clicking on a cell , I want the app open the file. I have no idea how to open the files picked before. Please help.

import UIKit

extension ViewController: UIDocumentMenuDelegate {
    func documentMenu(documentMenu: UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
        documentPicker.delegate = self

        self.presentViewController(documentPicker, animated: true, completion: nil)
    }
}

extension ViewController: UIDocumentPickerDelegate {
    func documentPicker(controller: UIDocumentPickerViewController, didPickDocumentAtURL url: NSURL) {
        if controller.documentPickerMode == UIDocumentPickerMode.Import {
          dispatch_async(dispatch_get_main_queue()) {

              if let fileName = url.lastPathComponent {

                self.files.append(fileName)

            }

          }            
        }      
    }        
}

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    var files = [AnyObject]()

    @IBOutlet weak var fileTableView: UITableView!
    @IBAction func addDocuments(sender: AnyObject) {
        let importMenu = UIDocumentMenuViewController(documentTypes: ["public.data", "public.text"], inMode: .Import)

        importMenu.delegate = self

        self.presentViewController(importMenu, animated: true, completion: nil)

        let documentPicker = UIDocumentPickerViewController(documentTypes: ["public.data", "public.text"], inMode: .Import)
        documentPicker.delegate = self
        documentPicker.modalPresentationStyle = UIModalPresentationStyle.FullScreen

        self.presentViewController(documentPicker, animated: true, completion: nil)
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    }

You need to keep a reference to the entire URL, not just the filename.

Add the full url to self.files . Then update your cellForRowAtIndexPath to show just the lastPathComponent of that URL.

Then in didSelectRowAtIndexPath you have the access to the full URL of the file.
