Swift自定义展开从导航控制器到View Controller的Segue

我有2个控制器：

• 第一视图控制器（1）

• 第二视图控制器（2）嵌入导航控制器（2a）

（1） - >（2a - 2）

和VC之间定制Segue导航：

• 正常的CustomSegue . 从1到2

• 展开CustomUnwindSegue . 从2到1

当我使用普通segue时：第二个控制器（包括导航栏!!!）从右侧推出第一个控制器

当我使用展开segue时：第一个控制器推动第二个控制器（没有导航栏!!!仅在导航控制器内部查看）到右侧 . 导航栏很粘！当导航完成栏消失时 .

如何使用导航栏推送View Controller .

我的代码：

class CustomSegue: UIStoryboardSegue {

    override func perform() {

        let toViewController: UIViewController = self.destinationViewController as! UIViewController
        let fromViewController: UIViewController = self.sourceViewController as! UIViewController

        let containerView: UIView? = fromViewController.view.superview
        let screenBounds: CGRect = UIScreen.mainScreen().bounds

        let finalToFrame: CGRect = screenBounds
        let finalFromFrame: CGRect = CGRectOffset(finalToFrame, -screenBounds.size.width, 0)

        toViewController.view.frame = CGRectOffset(finalToFrame, screenBounds.size.width, 0)
        containerView?.addSubview(toViewController.view)

        UIView.animateWithDuration(0.5, animations: {

            toViewController.view.frame = finalToFrame
            fromViewController.view.frame = finalFromFrame

            }, completion: { finished in
                let fromVC: UIViewController = self.sourceViewController as! UIViewController
                let toVC: UIViewController = self.destinationViewController as! UIViewController
                fromVC.presentViewController(toVC, animated: false, completion: nil)
        })
    }
}

class CustomUnwindSegue: UIStoryboardSegue {

    override func perform() {

        let toViewController: UIViewController = self.destinationViewController as! UIViewController
        let fromViewController: UIViewController = self.sourceViewController as! UIViewController

        let containerView: UIView? = fromViewController.view.superview
        let screenBounds: CGRect = UIScreen.mainScreen().bounds

        let finalToFrame: CGRect = screenBounds
        let finalFromFrame: CGRect = CGRectOffset(finalToFrame, screenBounds.size.width, 0)

        toViewController.view.frame = CGRectOffset(finalToFrame, -screenBounds.size.width, 0)
        containerView?.addSubview(toViewController.view)

       UIView.animateWithDuration(0.5, animations: {

            toViewController.view.frame = finalToFrame
            fromViewController.view.frame = finalFromFrame

            }, completion: { finished in
                let fromVC: UIViewController = self.sourceViewController as! UIViewController
                let toVC: UIViewController = self.destinationViewController as! UIViewController
                fromVC.dismissViewControllerAnimated(false, completion: nil)
        })
    }
}
