Pass image from collectionview to VC

Question

I've tried a lot of methods i couldn't get it to work

ViewController 1 have : Collectionview > Cell > image inside the cell

ViewController 2 want to display the image which in VC 1

When you click on cell it has segue to push you to VC 2

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

    if segue.identifier == "popup" {

        let viewController: friendpopup = segue.destination as! friendpopup
        let indexPath = sender as! NSIndexPath
        let nicknamex = self.nicknameArray[indexPath.row]
        let usernamex = self.userArray[indexPath.row]
        let photox = self.friendsphotos[indexPath.row] // the photos PFFiles i think


        viewController.snick = nicknamex
        viewController.suser = usernamex
        viewController.sphoto = // ????
}

nickname and user works fine only the image i couldn't display it.

I tried when you click on cell it will send the image to var but isn't working

var photovar:UIImage!

didSelectItemAt( self.photovar = cell.profilepic.image) then in prepareSegue( viewcontroller.sphoto = self.photovar)

isn't woking, Anyone could help me to fix that to display the image? Thanks

What do you mean by "isn't working"? ...compile error? ...crash? ...? — Phillip Mills, Nov 11 '16 at 19:59

Tightening up your code a bit....

First VC

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "popup" {
        if let vc = segue.destination as? friendpopup {
            let indexPath = sender as! NSIndexPath
            vc.snick = self.nicknameArray[indexPath.row]
            vc.suser = self.userArray[indexPath.row]
            vc.sphoto = self.friendsphotos[indexPath.row]
        }
    }
}

Second VC:

// making assumptions on variable types
var snick:String!
var suser:String!
var sphoto:UIImage!

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    // do work here
    if sphoto != nil {
        imageView.image = sPhoto
    } else {
        // set a default image here
    }
}

Most of this is similar to your code, but one last note - if the first 2 properties are coming across correctly, check in the first VC that you are pulling the image out properly.

Thank you, but this wont work because include friendsphotos PFFile, i'm working on Parse. I have tried that it gonna be nil, I just solved my problem, Its just to append photos while to download them in array then you can take them. — Salah, Nov 11 '16 at 21:40
