How to transfer image with Parse TableView - ios

Question

I want to transfer a file or a string from a cell on the table to my viewcontroller with parse but i'm completely stuck. Here is my code for segue
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "mySegue" {
let segue: myController = segue.destinationViewController as! myController
let segue2 = tableView.indexPathForSelectedRow?.row
segue.myLabelInViewController = objects[segue2!] as! String
}
}
And here is another code for UIImage transfer
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "mySegue" {
let segue: myController = segue.destinationViewController as! myController
let segue2 = tableView.indexPathForSelectedRow?.row
segue.myUIImageView.image = UIImage(data: objects[segue2!])
}
}

I think you have a few issues going on. First, if you're using a PFQueryTableViewController, objects is an array of PFObjects. This means you will want to either pass the entire PFObject to the destination view controller or you could pass individual properties.
Second, try the following in your table view controller to pass the whole object. In the destination view controller we can set the UILabel and UIImage.
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "mySegue" {
// Get the new view controller using [segue destinationViewController]
var detailScene = segue.destinationViewController as! myController
// Pass the selected object to the destination view controller
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = (objects?[row] as! PFObject)
}
}
}
Next, add the following to the top of your detail (destination) view controller
// Container to store the view table selected object
var currentObject : PFObject?
When the detail view controller loads, take the contents of currentObject and push the values into the appropriate labels and images so that they are displayed. Update your viewDidLoad() method to look like this.
override func viewDidLoad() {
super.viewDidLoad()
// Unwrap the current object
if let object = currentObject {
myLabelInViewController.text = object["someString"] as! String
myUIImageView.image = UIImage(data: object["someImageData"] as! NSData)
}
}
