passing the imageView to the next activity, does it require an outlet - ios

Question

I have minor problem that whenever I delete the Outlet (imageChosen) shown in the picture below (with the yellow warning), the app crashes when the image supposed to be passed
here how i defined it
var imageChosen: UIImageView!
this is how i saved the image chosen from the gallery to the imageChosen
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
var chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
imageChosen.contentMode = .ScaleAspectFit
imageChosen.image = chosenImage
dismissViewControllerAnimated(true, completion: nil)
self.performSegueWithIdentifier("next", sender: self)
}
this where I pass the image to the next activity
override func prepareForSegue(segue: (UIStoryboardSegue!), sender: AnyObject!) {
if segue.identifier == "next" {
var pass:postView = segue.destinationViewController as! postView
pass.currentImage = imageChosen.image
}
}
when I delete the outlet in the picture, the app crashes because the image is nil, even though the code seems to be okay,
can anyone please help me

Answer 1

The reason why you keep getting the error is because you are assign image without allocation of your imageChosen.
The Solution
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
// Add this line
imageChosen = UIImageView()
}
After you have declare that imageChosen = UIImageView(), it will solve your problem
Hope that helps!

You need to delete the outlet from the ViewController(swift file) as well, where you see the outlets in the pic you post click in the (x) to delete the outlet from imageChosen as it does not exist anymore (you can see the warning from Code in form of a yellow triangle).
You should also change your code to:
var imageChosen: UIImageView?
this is how i saved the image chosen from the gallery to the imageChosen
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let image = info[UIImagePickerControllerOriginalImage] as UIImage{
imageChosen.contentMode = .ScaleAspectFit
imageChosen.image = image
}
else
{
//something went wrong
}
dismissViewControllerAnimated(true, completion: nil)
self.performSegueWithIdentifier("next", sender: self)
}
this where I pass the image to the next activity
override func prepareForSegue(segue: (UIStoryboardSegue!), sender: AnyObject!) {
if segue.identifier == "next" {
if let pass = segue.destinationViewController as postView
{
if let image = imageChosen.image{
pass.currentImage = imageChosen.image
}
}
}
}
I did it very verbose to make it easier to understand
