Customsegue中的多维数据集效果错误

Question

我想在多维数据集上提供我的项目customsegue效果。 UIStoryboard认为这段代码。然而，立方体效应不会发生。我想知道我哪里出错了？

import UIKit
import QuartzCore

class CubeSegue: UIStoryboardSegue {

override func perform() {
   let source:UIViewController = self.sourceViewController as UIViewController
   let destination:UIViewController = self.destinationViewController as UIViewController

    let transition = CATransition()
    transition.type = "cube"
    transition.duration = 0.5
    transition.subtype = kCATransitionFromRight
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)

   self.sourceViewController.navigationController!!.pushViewController(self.destinationViewController as UIViewController, animated: true)
IS}
}

感谢您的帮助。

我需要以这种方式编写代码..

override func perform() {
    let source = self.sourceViewController as UIViewController;
    let destination = self.destinationViewController as UIViewController;

    let animation = CATransition()
    animation.type = "cube"
    animation.duration = 0.5
    animation.subtype = kCATransitionFromRight
    animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)

        source.navigationController?.view.layer.addAnimation(animation, forKey: kCATransition);
        source.navigationController?.pushViewController(destination, animated: true);

}
