正如提到的 Heximal scrollview 具有属性 pagingEnabled 您需要启用它才能在 scrollview 中进行分页

你的示例代码可以是这样的:

@IBOutlet weak var scrollPagination: UIScrollView!
var numberOfPages:CGFloat = 5

override func viewDidLoad() {

    super.viewDidLoad()

    scrollPagination.pagingEnabled = true
    scrollPagination.contentSize = CGSizeMake(numberOfPages * scrollPagination.frame.size.width, scrollPagination.frame.size.height)

    for i in 0...Int(numberOfPages) {
        let tmpLabel: UILabel = UILabel(frame: CGRectMake(CGFloat(i) * self.view.bounds.width + 20, 20, 120, 20))
        tmpLabel.textAlignment = .Center
        tmpLabel.text = "This is page \(i)"
        scrollPagination.addSubview(tmpLabel)
    }
}
