ios - 多个 ScrollView 彼此内部

Question

我在水平 ScrollView 中有一个垂直分页 ScrollView 。 水平 ScrollView 有效，但垂直 ScrollView 无效。

我在垂直 ScrollView 上使用了 scrollView.contentSize=CGSize(500,2000) 但它仍然不起作用。

现在问题是什么？

我应该说，垂直的添加到 View 中，以编程方式使用 xib。

这是我的Main.swift(我没有 Storyboard):

class test: UIViewController {

@IBOutlet weak var scroll: UIScrollView!
override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

override func viewDidLayoutSubviews() {

    let myView3:TourDetailsDescription = TourDetailsDescription(frame: CGRect(x: 0, y: 0, width: scroll.frame.width, height: scroll.frame.height))
    myView3.getView().frame.origin.x = CGFloat(2*scroll.frame.width)
    scroll.addSubview(myView3)

    let img1:UIImageView = UIImageView(image: UIImage(named: "kavir"))
    img1.frame = CGRect(x: 0, y: 0, width: 300, height: 600)
    myView3.mainScroll.addSubview(img1)
    myView3.mainScroll.contentSize = CGSize(width: 300, height: 600)


    self.scroll.contentSize = CGSize(width:UIScreen.main.bounds.width * CGFloat(2), height:self.scroll.frame.height)
}
}

和我的TourDetailsDescription.swift:

类 TourDetailsDescription:UIView {

@IBOutlet weak var mainScroll: UIScrollView!
var parent:UIView!
@IBOutlet var contentView: UIView!

override init(frame: CGRect) {
    super.init(frame: frame)
    commitInit()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    commitInit()
}
private func commitInit(){
    Bundle.main.loadNibNamed("TourDetailsDescription", owner: self, options: nil)
    addSubview(contentView)
    contentView.frame = self.bounds
    contentView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
}

func getView()->UIView{
    return contentView
}
}

也许这对你有帮助:)，这是在 Playground 上工作

class ScrollingViewController : UIViewController {

override func loadView() {

    let contentView = UIView(frame: CGRect(x: 0, y: 20, width: 2000, height: 200))
    contentView.backgroundColor = .green

    let scrollView = UIScrollView()
    scrollView.contentSize = contentView.frame.size
    scrollView.addSubview(contentView)
    scrollView.flashScrollIndicators()
    scrollView.backgroundColor = .white

    let verticalContainerView = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
    verticalContainerView.backgroundColor = .blue

    let verticalContentView = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 2000))
    verticalContentView.backgroundColor = .red

    let verticalScrollView = UIScrollView(frame: verticalContainerView.frame)
    verticalScrollView.contentSize = verticalContentView.frame.size
    verticalScrollView.addSubview(verticalContentView)
    scrollView.flashScrollIndicators()
    verticalScrollView.backgroundColor = .white

    verticalContainerView.addSubview(verticalScrollView)

    contentView.addSubview(verticalContainerView)

    self.view = scrollView
}

}
