所以我想要做的是我有一個UICollectionViewController與單元格的圖像和視頻，我希望它，所以當你點擊視頻它全屏播放視頻。我已經爲這些圖像製作了這個圖片，但是我不太清楚如何爲視頻執行此操作？因此，使用圖像時，點擊圖像（單元格），圖像將以黑色背景視圖進入屏幕中央。我想合併相同的東西，但與視頻，當然，視頻將播放等...從全屏顯示一個單元格的視頻Swift 我從Firebase獲取視頻。 碼是什麼我對圖像： import UIKit import Firebase import MobileCoreServices import AVFoundation class ImagesAndVideosController: UICollectionViewController, UICollectionViewDelegateFlowLayout { lazy var messageImageView: UIImageView = { let imageView = UIImageView() imageView.translatesAutoresizingMaskIntoConstraints = false imageView.layer.cornerRadius = 16 imageView.layer.masksToBounds = true imageView.contentMode = .scaleAspectFill imageView.isUserInteractionEnabled = true imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleZoomTap))) return imageView }() func handleZoomTap(_ tapGesture: UITapGestureRecognizer) { if message?.videoUrl != nil { return } if let imageView = tapGesture.view as? UIImageView { self.chatLogController?.performZoomInForStartingImageView(imageView) } } var startingFrame: CGRect? var blackBackgroundView: UIView? var startingImageView: UIImageView? func performZoomInForStartingImageView(_ startingImageView: UIImageView) { self.startingImageView = startingImageView self.startingImageView?.isHidden = true startingFrame = startingImageView.superview?.convert(startingImageView.frame, to: nil) let zoomingImageView = UIImageView(frame: startingFrame!) zoomingImageView.backgroundColor = UIColor.red zoomingImageView.image = startingImageView.image zoomingImageView.isUserInteractionEnabled = true zoomingImageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleZoomOut))) if let keyWindow = UIApplication.shared.keyWindow { blackBackgroundView = UIView(frame: keyWindow.frame) blackBackgroundView?.backgroundColor = UIColor.black blackBackgroundView?.alpha = 0 keyWindow.addSubview(blackBackgroundView!) keyWindow.addSubview(zoomingImageView) UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: { self.blackBackgroundView?.alpha = 1 self.inputContainerView.alpha = 0 // math? // h2/w1 = h1/w1 // h2 = h1/w1 * w1 let height = self.startingFrame!.height/self.startingFrame!.width * keyWindow.frame.width zoomingImageView.frame = CGRect(x: 0, y: 0, width: keyWindow.frame.width, height: height) zoomingImageView.center = keyWindow.center }, completion: { (completed) in // do nothing }) } } func handleZoomOut(_ tapGesture: UITapGestureRecognizer) { if let zoomOutImageView = tapGesture.view { //need to animate back out to controller zoomOutImageView.layer.cornerRadius = 16 zoomOutImageView.clipsToBounds = true UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: { zoomOutImageView.frame = self.startingFrame! self.blackBackgroundView?.alpha = 0 self.inputContainerView.alpha = 1 }, completion: { (completed) in zoomOutImageView.removeFromSuperview() self.startingImageView?.isHidden = false }) } }} 我很抱歉，如果我提出沒有多大意義的代碼，我相信大家都知道，這東西是超級保密的，所以我不得不剪切和粘貼足以顯示，但不是全部。我再次道歉。 我也有一個播放按鈕，所以當有一個視頻加載到收藏視圖中時，它會知道並在其上面放置播放按鈕，以便播放視頻，但視頻播放在單元內部，這就是爲什麼我希望它能夠到達中心（就像你在大多數應用中看到的那樣）。 謝謝你這麼多！我希望我提供了足夠的信息？ 來源 2017-08-08 Jaqueline |
