在scrollview ios swift中添加视图控制器

Question

我有带滚动视图的 baseview 控制器。在该滚动视图中，我添加了三个视图控制器视图（xib）。所以我可以水平滚动这三个。在我的第一个视图控制器中，我正在显示一个 tableview。在运行我的应用程序时，它正在显示我所有的 3 个视图控制器。但是当我触摸我的 tableview 单元格时消失了。我在 xcode 7.3 中所做的一样。它工作正常。但在 xcode 8 中它不起作用。请帮我解决这个问题。我附上了我的示例代码

let scrollViewWidth:CGFloat = self.scrollContainer.frame.width
        let scrollViewHeight:CGFloat = self.scrollContainer.frame.height
        let x = CGFloat(i) * scrollViewWidth

        if i == 0{
            let qualification = EducationViewController (nibName: "EducationViewController", bundle: nil)
            //qualification.view.frame.size.height = scrollViewHeight
            //qualification.view.frame.size.width = scrollViewWidth
            qualification.view.frame.origin.x = x
            self.scrollContainer!.addSubview(qualification.view)
            qualification.didMove(toParentViewController: self)
        }
        else if i == 1{
            let state = StateRegistrationViewController (nibName: "StateRegistrationViewController", bundle: nil)
            //state.view.frame.size.height = scrollViewHeight
           // state.view.frame.size.width = scrollViewWidth
            state.view.frame.origin.x = x
            self.scrollContainer!.addSubview(state.view)
            state.view.backgroundColor = UIColor.red
            state.didMove(toParentViewController: self)
        }
        else if i == 2{
            let exp = ExperienceViewController (nibName: "ExperienceViewController", bundle: nil)
           // exp.view.frame.size.height = scrollViewHeight
           // exp.view.frame.size.width = scrollViewWidth
            exp.view.frame.origin.x = x
            self.scrollContainer!.addSubview(exp.view)
            exp.view.backgroundColor = UIColor.orange

            exp.didMove(toParentViewController: self)
        }}

1. 启动视图控制器

   let storyboard = UIStoryboard(name: "Main", bundle: nil)
   let aViewController = storyboard.instantiateViewController(withIdentifier: "A") as! AViewController;
   let bViewController = storyboard.instantiateViewController(withIdentifier: "B") as! BViewController;
   let cViewController = storyboard.instantiateViewController(withIdentifier: "C") as! CViewController;
   

2. 将视图控制器添加到数组中

   let viewControllers = [aViewController, bViewController, cViewController]
   

3. 运行将 viewControllers 添加到滚动视图的 for 循环

   var idx:Int = 0
   for viewController in viewControllers {
   
       addChildViewController(viewController);
       let originX:CGFloat = CGFloat(idx) * width;
       viewController.view.frame = CGRect(x: originX, y: 0, width: width, height: height);
       scrollView!.addSubview(viewController.view)
       viewController.didMove(toParentViewController: self)
       idx += 1;
   }
   

全部完成！

在滚动视图上添加自定义视图控制器的视图时，您还应该将自定义视图控制器添加为主控制器的子控制器。

就像您的情况一样，您有三个自定义控制器，然后根据代码中的 if else 子句，您必须添加：

self.addChildViewController(qualification)
self.addChildViewController(state)
self.addChildViewController(exp)

在代码中的相应块中。

你的代码会是这样的：

let scrollViewWidth:CGFloat = self.scrollContainer.frame.width
        let scrollViewHeight:CGFloat = self.scrollContainer.frame.height
        let x = CGFloat(i) * scrollViewWidth

        if i == 0{
            let qualification = EducationViewController (nibName: "EducationViewController", bundle: nil)
            //qualification.view.frame.size.height = scrollViewHeight
            //qualification.view.frame.size.width = scrollViewWidth
            qualification.view.frame.origin.x = x
            self.scrollContainer!.addSubview(qualification.view)
            self.addChildViewController(qualification)
            qualification.didMove(toParentViewController: self)
        }
        else if i == 1{
            let state = StateRegistrationViewController (nibName: "StateRegistrationViewController", bundle: nil)
            //state.view.frame.size.height = scrollViewHeight
           // state.view.frame.size.width = scrollViewWidth
            state.view.frame.origin.x = x
            self.scrollContainer!.addSubview(state.view)
            self.addChildViewController(state)
            state.view.backgroundColor = UIColor.red
            state.didMove(toParentViewController: self)
        }
        else if i == 2{
            let exp = ExperienceViewController (nibName: "ExperienceViewController", bundle: nil)
           // exp.view.frame.size.height = scrollViewHeight
           // exp.view.frame.size.width = scrollViewWidth
            exp.view.frame.origin.x = x
            self.scrollContainer!.addSubview(exp.view)
            self.addChildViewController(exp)
            exp.view.backgroundColor = UIColor.orange

            exp.didMove(toParentViewController: self)
        }}
