【英文标题】：How To Create Animation of Segue perform and unwind segue?

【问题描述】：

我正在开发我试图用动画调用控制器的应用程序 第二个带有动画的视图控制器 就像我用 segue 调用第二个控制器时一样 第二个控制器来自右边，第一个控制器开始向左移动 像 android push pop 动画

我写了一些代码

class SegueFromRight: UIStoryboardSegue 
override func perform() 
    let src = self.source
    let dst = self.destination

    src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)
    dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width*2, y: 0)
    //Double the X-Axis
    UIView.animate(withDuration: 0.25, delay: 0.0, options: UIView.AnimationOptions.curveEaseInOut, animations: 
        dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
    )  (finished) in
        src.present(dst, animated: false, completion: nil)
    

但是从这段代码中，新控制器来自右侧，我也需要移动当前控制器向左移动 如果有人可以帮忙

【参考方案1】：

试试这个代码：

class CustomSegue: UIStoryboardSegue 
    override func perform() 
        let firstVCView: UIView = self.source.view
        let secondVCView: UIView = self.destination.view
        self.destination.modalPresentationStyle = .fullScreen

        let screenWidth = UIScreen.main.bounds.size.width
        let screenHeight = UIScreen.main.bounds.size.height

        secondVCView.frame = CGRect(x: screenWidth, y: 0, width: screenWidth, height: screenHeight)

        let window = UIApplication.shared.keyWindow
        window?.insertSubview(secondVCView, aboveSubview: firstVCView)

        UIView.animate(withDuration: 0.4, animations:  () -> Void in
            firstVCView.frame = firstVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
            secondVCView.frame = secondVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
               )  (Finished) -> Void in
                self.source.present(self.destination as UIViewController,
                       animated: false,
                       completion: nil)
           
    



class CustomSegueUnwind: UIStoryboardSegue 
    override func perform() 
        let secondVCView: UIView = self.source.view
        let firstVCView: UIView = self.destination.view
        self.destination.modalPresentationStyle = .fullScreen

        let screenWidth = UIScreen.main.bounds.size.width

        let window = UIApplication.shared.keyWindow
        window?.insertSubview(firstVCView, aboveSubview: secondVCView)

        UIView.animate(withDuration: 0.4, animations:  () -> Void in
            firstVCView.frame = firstVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
            secondVCView.frame = secondVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
               )  (Finished) -> Void in
                self.source.dismiss(animated: false, completion: nil)

【讨论】：

谢谢它也适用于 unwind？因为当我执行 segues 时它工作得很好

@MuhammadWaqas 我添加了放松类。希望对您有所帮助

你能指导我吗？我是 ios 的初学者，我添加了 unwind 功能，它关闭了控制器，但是当我按下后退按钮时，控制器关闭，但在 segue 上，它可以很好地使用你的代码

@MuhammadWaqas 观看 this video for unwind segue。如果我的回答对您的问题有帮助，请投票或检查它是否正确（或两者兼而有之）。谢谢兄弟！

谢谢兄弟，这与我在 ios 中想要的完全一样，你很棒：D
