iOS) Scrollview Programmatically (코드로 작성)

예제 코드~

let scrollview : UIScrollView =
    {
        let sv = UIScrollView()
        sv.translatesAutoresizingMaskIntoConstraints = false
        //sv.backgroundColor = .black
        sv.isPagingEnabled = true //이걸해야지 한번 슬라이드할때마다 다음 화면으로 획 넘어감
        return sv
    }()
    
    var images : [UIImage] = [#imageLiteral(resourceName: "IMG_0058"),#imageLiteral(resourceName: "IMG_0058"),#imageLiteral(resourceName: "IMG_0058")]
    
    //scrollview 크기조절은 내키는데로~~
    
    func fitmeImages()
    {
        print(fitme_images_scrollview.frame.width)
        for i in 0..<images.count
        {
            let scroll_imageView = UIImageView()
            scroll_imageView.image = self.images[i]
            
            let xPosition = self.scrollview.frame.width * CGFloat(i)
            scroll_imageView.contentMode = .scaleAspectFit
            scroll_imageView.frame = CGRect(x: xPosition, y: 0, width: self.scrollview.frame.width, height: self.scrollview.frame.height)
            scroll_imageView.center = .init(x: self.scrollview.frame.width / 2 + xPosition, y: scrollview.frame.height / 2)
            scrollview.contentSize.width = scrollview.frame.width * CGFloat(i + 1)
            crollview.addSubview(scroll_imageView)
        }
    }
