ios - ContainerView Inside ScrollView 不要在 Swift 3 中滚动

Question

我在 GitHub 上有示例项目，您可以在 -> 上看到 https://github.com/LetSwiftDev/ContainerViewInsideScroll/tree/master

我有两个， View Controller ，一个是普通的 View Controller ，名为 oneViewController 第二个是 twoViewController 里面有 UIScrollView 当我点击 OPEN TWO 按钮将转到 ContainerView 内的 twoViewController 但是；

My twoViewController have different height size like 1500 and inside have scrollview and don't scroll to bottom? I didn't see middle side, bottom side labels.

我该如何解决？有什么想法吗？

下面还有我的 centerViewController 代码。我正在使用 centerViewController

控制过去的 View Controller

import UIKit

open class centerViewController: UIViewController {
    fileprivate weak var viewController : UIViewController!
    fileprivate var containerViewObjects = Dictionary<String,UIViewController>()

    open var currentViewController : UIViewController{
        get {
            return self.viewController

        }
    }


    fileprivate var segueIdentifier : String!

    @IBInspectable internal var startUp : String!


    override open func viewDidLoad() {
        super.viewDidLoad()



    }
    open override func viewDidAppear(_ animated: Bool) {
        if let identifier = startUp{
            segueIdentifierReceivedFromParent(identifier)
        }
    }
    override open func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    func segueIdentifierReceivedFromParent(_ identifier: String){

        self.segueIdentifier = identifier
        self.performSegue(withIdentifier: self.segueIdentifier, sender: nil)

    }




    override open func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == segueIdentifier{

            if viewController != nil{


                viewController.view.removeFromSuperview()
                viewController = nil

            }
            if ((self.containerViewObjects[self.segueIdentifier] == nil)){
                viewController = segue.destination
                self.containerViewObjects[self.segueIdentifier] = viewController

            }else{
                for (key, value) in self.containerViewObjects{

                    if key == self.segueIdentifier{

                        viewController = value


                    }

                }


            }

            self.addChildViewController(viewController)
            viewController.view.frame = CGRect(x: 0,y: 0, width: self.view.frame.width,height: self.view.frame.height)
            self.view.addSubview(viewController.view)
            viewController.didMove(toParentViewController: self)


        }

    }


}

这是带有解决方案的演示。你可以在这里下载 https://www.dropbox.com/s/zvrjd0gp06xe5nw/ContainerViewInsideScroll-master%202.zip?dl=0

问题是你必须学习 Scrollview 的自动布局。

我只是针对给定的 ScrollView 约束提供提示。

先取scrollview适配屏幕，如下约束

现在在 scrollview 中获取一个 View 并适合 scrollview 并给出类似的约束

仍然给出约束错误。所以现在，给 scrollview 相同的 View 宽度

现在您可以根据需要进行任意多的控制，并像我们对其他控件一样正常地给予约束。

希望你能理解。
享受编码。
