Question

我有 UIScrollView ，其中包含许多订阅视图控制器。每个订阅视图控制器包含容器视图控制器。

目标是在右侧的4个视图控制器之间进行简单导航。

导航逻辑：

在 viewDidLoad 上显示容器

View Controller

当用户按下 View Controller 上的按钮时，在容器

View Controller

我尝试使用 Segues ，但这不起作用。实例化VC的方法 订阅视图控制器不是一个好主意。

Answer 1

使用此代码切换容器视图视图...

@IBOutlet weak var container: UIView!
   var currentViewController:UIViewController?

//put the view did load method here.



    @IBAction func buttonPressed() {

//the storyboard file that the view is in.
        let storyboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)


// the container view you want to switch to.
   self.currentViewController = storyboard.instantiateViewControllerWithIdentifier("containerViewStoryboardID") as? UIViewController


//switch the container view.
        self.addChildViewController(self.currentViewController!)

        self.container.addSubview(self.currentViewController!.view)

        self.currentViewController!.didMoveToParentViewController(self)


}

我发现最简单的方法是创建自定义 Segue 。 enter image description here

创建自定义UIStoryboardSegue

转到文件 - ＆gt; 新 - ＆gt; 文件... 并选择 Cocoa Class

enter image description here

从 UIStoryboardSegue

enter image description here

配置 MySegue

import UIKit

class NewSegue: UIStoryboardSegue {

    //Call when performSegueWithIdentifier() called
    override func perform() {
        //ViewController segue FROM
        var sourceViewController: UIViewController = self.sourceViewController as! UIViewController
        //ViewController segue TO
        var destinationViewController: UIViewController = self.destinationViewController as! UIViewController
        //Parent ViewController - ContainerViewController
        var containerViewController: UIViewController = sourceViewController.parentViewController!

        //Setting destinationViewController
        containerViewController.addChildViewController(destinationViewController)
        destinationViewController.view.frame = sourceViewController.view.frame
        sourceViewController.willMoveToParentViewController(nil)

        //Do animation
        containerViewController.transitionFromViewController(sourceViewController,
            toViewController: destinationViewController,
            duration: 0.3,
            options: UIViewAnimationOptions.TransitionCrossDissolve,
            animations: nil, completion: { finished in
                //Delete sourceViewController
                sourceViewController.removeFromParentViewController()
                //Show destinationViewController
                destinationViewController.didMoveToParentViewController(containerViewController)
        })
    }
}

转到 Storyboard 文件并控制从 ContainerViewController 拖动到所需的控制器，然后在上下文菜单中选择自定义

3.点击创建的segue并配置它们

enter image description here

现在，您可以在 ContainerViewController 或其他 ViewController

performSegueWithIdentifier("SugueID", sender: self)
