I created a modal popup in storyboard, so that when an image is clicked there is a popup of that image, but resizable. All I want is so that the popup is equal to the size of the superview (programmatically).
I will provide additional code if needed.
@IBOutlet var imageView: UIView!
@IBOutlet weak var scrollView: UIScrollView!
@IBOutlet weak var zoomImageView: UIImageView!
@IBOutlet weak var backgroundButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.setNavigationBarHidden(true, animated: false)
imageView.layer.cornerRadius = 10
imageView.layer.masksToBounds = true
self.scrollView.minimumZoomScale = 1.0
self.scrollView.maximumZoomScale = 6.0
}
func viewForZooming(in scrollView: UIScrollView) -> UIView? {
return self.zoomImageView
}
override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
if UIDevice.current.orientation.isLandscape{
imageView.center = self.view.center
imageView.frame = view.frame
} else if UIDevice.current.orientation.isPortrait{
imageView.center = self.view.center
imageView.frame = view.frame
}
}
@IBAction func showImageView(_ sender: Any) {
animateIn()
}
@IBAction func closeImageView(_ sender: Any) {
animateOut()
}
func animateIn() {
self.scrollView.zoomScale = 1.0
self.view.addSubview(imageView)
imageView.center = self.view.center
imageView.transform = CGAffineTransform.init(scaleX: 1.3, y: 1.3)
imageView.alpha = 0
self.backgroundButton.alpha = 0.7
UIView.animate(withDuration: 0.4) {
self.imageView.alpha = 1
self.imageView.transform = CGAffineTransform.identity
}
}
func animateOut() {
UIView.animate(withDuration: 0.3, animations: {
self.imageView.transform = CGAffineTransform.init(scaleX: 1.3, y: 1.3)
self.imageView.alpha = 0
self.backgroundButton.alpha = 0
}) { (success:Bool) in
self.imageView.removeFromSuperview()
}
}
}
Any help would be greatly appreciated.
Finally found the answer.
Instead of:
imageView.frame = self.view.frame
I just had to use:
imageView.frame = CGRect(x: 0, y: 0, width: self.view.bounds.width, height: self.view.bounds.height)
And in the animateOut() block I changed the transform scale to 1
self.image.transform = CGAffineTransform(scaleX: 1, y: 1)
All that fixed the problem.
