スクロールビューでページングとズームを有効にして表示したい画像配列(サーバーからダウンロード)がありますが、解決策が見つかりませんでした。私は多くを探していますが、私は何の解決策も得ていませんでした。UIscrollViewスピーディーなページングとズームの画像
本当にありがとうございます。 ありがとう!メインコントローラ
var mainScrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
var x:CGFloat = 0

let images=["image.png","photo.jpg","3.png"]
for var i = 0; i < images.count; i++

let imageView = UIImageView(image: UIImage(named: images[i]))

// Do any additional setup after loading the view.
