Good Evening. I am having trouble with transferring PFFile from my TableViewController to my SecondViewController. I want to be able for users to pick an image out of the tableview then edit the video how they see fit on the next view controller.
I am able to select the cell and transfer to the MovieDetailedViewController,if I remove the
if segue.identifier == "viewMe" {
if var indexPath = self.tableView.indexPathForSelectedRow() {
var object:PFObject = (self.resultsVideoFiles[indexPath.row] as? PFObject)!
var file:PFFile = object.objectForKey("video") as! PFFile
(segue.destinationViewController as! MovieDetailedViewController)
}
}
but the wrong video plays. How would I get the right video to play? And If I keep the same line of code under the prepareForSegue function then I get a break in my program saying Could not cast value of type 'PFFile' (0x10c4fff90) to 'PFObject'??
Here is the code to my first view controller.
import UIKit
import Parse
import ParseUI
class MovieListViewController: UITableViewController {
var resultsMovienameArray = [String]()
var resultsImageFiles = [PFFile]()
var resultsVideoFiles = [PFFile]()
var video:PFFile!
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewDidAppear(animated: Bool) {
resultsMovienameArray.removeAll(keepCapacity: false)
resultsImageFiles.removeAll(keepCapacity: false)
var query = PFQuery(className: "Videos")
var objects = query.findObjects()
for object in objects! {
self.resultsMovienameArray.append(object["name"] as! String)
self.resultsImageFiles.append(object["picture"] as! PFFile)
self.tableView.reloadData()
}
}
// MARK: - Table view data source
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
return resultsMovienameArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("movieCell", forIndexPath: indexPath) as! MovieViewCell
// Configure the cell...
cell.movieNameLblTxt.text = self.resultsMovienameArray[indexPath.row]
resultsImageFiles[indexPath.row].getDataInBackgroundWithBlock {
(imageData: NSData?, error:NSError?) -> Void in
if error == nil {
let image = UIImage(data: imageData!)
cell.movieImg.image = image
}
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
var cell = tableView.cellForRowAtIndexPath(indexPath) as! MovieViewCell
self.performSegueWithIdentifier("viewMe", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var detailScene = segue.destinationViewController as! MovieDetailedViewController
if segue.identifier == "viewMe" {
if var indexPath = self.tableView.indexPathForSelectedRow() {
var object:PFObject = (self.resultsVideoFiles[indexPath.row] as? PFObject)!
var file:PFFile = object.objectForKey("video") as! PFFile
(segue.destinationViewController as! MovieDetailedViewController)
}
}
}
}
Then here is my code to my SecondViewController
import UIKit
import MediaPlayer
import Parse
import ParseUI
class MovieDetailedViewController: UIViewController {
var moviePlayer:MPMoviePlayerController!
var detailItem: AnyObject?
var videoObject: PFObject!
override func viewDidLoad() {
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewDidAppear(animated: Bool) {
var query = PFQuery(className: "Videos")
query.findObjectsInBackgroundWithBlock { (objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
for object in objects! {
var theVideo:PFFile = object.objectForKey("video") as! PFFile
var url:NSURL = NSURL(string: theVideo.url!)!
theVideo.getDataInBackgroundWithBlock({ (data:NSData?, error: NSError?) -> Void in
if error == nil {
self.moviePlayer = MPMoviePlayerController(contentURL: url)
self.moviePlayer.view.frame = CGRect(x: 20, y: 100, width: 200, height: 150)
self.view.addSubview(self.moviePlayer.view)
self.moviePlayer.fullscreen = true
self.moviePlayer.controlStyle = MPMovieControlStyle.Embedded
self.moviePlayer.prepareToPlay()
self.moviePlayer.play()
}
})
}
}
}
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
I would greatly appreciate the help.
