我想在滚动视图中滚动五个按钮.当用户停止拖动按钮时,它应该移动到下一个按钮.我在这做错了什么？

class ViewController: UIViewController {

    @IBOutlet weak var categoryScrollView: UIScrollView!
    var categoryArr = ["Jack","Mark","Down","Bill","Steve"]

    override func viewDidLoad() {
        super.viewDidLoad()
        let scrollingView = colorButtonsView(CGSizeMake(150,categoryScrollView.frame.size.height), buttonCount: 5)
        categoryScrollView.contentSize = scrollingView.frame.size
        categoryScrollView.addSubview(scrollingView)
        categoryScrollView.showsVerticalScrollIndicator = false
        categoryScrollView.delegate = self
        categoryScrollView.pagingEnabled = true
        categoryScrollView.indicatorStyle = .Default
    }


func colorButtonsView(buttonSize:CGSize, buttonCount:Int) -> UIView {
        let buttonView = UIView()
        buttonView.frame.origin = CGPointMake(0,0)
        let padding = CGSizeMake(10, 10)
        buttonView.frame.size.width = (buttonSize.width + padding.width) * CGFloat(buttonCount)
        var buttonPosition = CGPointMake(padding.width * 0.5, padding.height)
        let buttonIncrement = buttonSize.width + padding.width …
