Pass image from collectionview to VC - swift

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

Answer 1

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.
