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.
