我在情节提要中创建了一个模态弹出窗口，以便在单击图像时会弹出该图像的弹出窗口，但可以调整大小。我想要的只是使弹出窗口等于超级视图的大小（以编程方式）。
如果需要，我会提供额外的代码。
@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()
}
}
}
任何帮助将不胜感激。
