Move image to other view with double tap - ios

Question

I am new to Swift and I am looking for a way to move my image to other view controller with double tap.
I made my image into scroll view, so I can slide to view it.
Here is my code.
class Quotes: UIViewController, UIScrollViewDelegate {
#IBOutlet weak var scroll: UIScrollView!
let imageview = ["quotes1","quotes2","quotes3","quotes4"]
var imagine = UIImageView()
override func viewDidLoad() {
let tap = UITapGestureRecognizer(target: self, action: #selector(doubletap))
tap.numberOfTapsRequired = 2
view.addGestureRecognizer(tap)
self.navigationController?.setNavigationBarHidden(true, animated: true)
quotesimageload()
}
func quotesimageload() {
for index in 0 ... imageview.count - 1
{
imagine = UIImageView (frame:CGRect(x: self.scroll.frame.width * CGFloat(index), y: 0 , width: self.scroll.frame.width, height: self.scroll.frame.height))
imagine.image = UIImage(named : imageview[index])
imagine.tag = index
imagine.autoresizingMask = [.flexibleWidth, .flexibleHeight]
self.scroll.addSubview(imagine)
}
self.scroll.contentSize = CGSize(width: self.scroll.frame.width * CGFloat(imageview.count), height: self.scroll.frame.height)
}
func doubletap(){
let view = self.storyboard?.instantiateViewController(withIdentifier: "pinch")
self.navigationController?.pushViewController(view!, animated: true)
}
}

You don't exactly move the image to another view controller - you pass a copy of it to the target VC.
Set up a "var" UIImage in the secondVC (let's say you called it image) and before you push that VC into view, populate it from the first VC.
One more word of caution - naming a UIViewController as "view" can be very confusing, as many would think it's a UIView. So assuming you rename that to be pinchViewController, the full syntax would be:
Second VC:
var image:UIView!
First VC:
func doubletap(){
let pinchViewController = self.storyboard?.instantiateViewController(withIdentifier: "pinch")
pinchViewController.image = imagine.image
self.navigationController?.pushViewController(view!, animated: true)
}
And if you have things properly coded and/or wired up in IB, you should have you UIImageView in the second VC displaying the image.
