记住，在Swift中，扩展绝对是你的朋友!

public extension UINavigationController {

    /**
     Pop current view controller to previous view controller.

     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func pop(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.popViewControllerAnimated(false)
    }

    /**
     Push a new view controller on the view controllers's stack.

     - parameter vc:       view controller to push.
     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func push(viewController vc: UIViewController, transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.pushViewController(vc, animated: false)
    }

    private func addTransition(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = type
        self.view.layer.addAnimation(transition, forKey: nil)
    }

}

@Luca Davanzo的答案在Swift 4.2

public extension UINavigationController {

    /**
     Pop current view controller to previous view controller.

     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func pop(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.popViewController(animated: false)
    }

    /**
     Push a new view controller on the view controllers's stack.

     - parameter vc:       view controller to push.
     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func push(viewController vc: UIViewController, transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.pushViewController(vc, animated: false)
    }

    private func addTransition(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        transition.type = type
        self.view.layer.add(transition, forKey: nil)
    }

}

如何改变一个基于导航的应用程序的推送和弹出动画…

如果你是iOS开发新手。对于最简单、最常见的动画(如“滑动”或“一个推另一个”)，你必须做大量的工作。

1. 你需要一个自定义的uiviewcontrolleranimatedtransiting

You need popStyle boolean - is it popping on, or popping off? You must include transitionDuration (trivial) and the main call, animateTransition You must write the two different animations routines, one for the push, and one for the pop. Inside animateTransition, simply branch on the boolean popStyle to one the two routines The example below does a simple move-over/move-off In your animatePush and animatePop routines. You must get the "from view" and the "to view". (How to do that, is shown in the code example.) and you must addSubview for the new "to" view. and you must call completeTransition at the end of your anime

复制粘贴…

  class SimpleOver: NSObject, UIViewControllerAnimatedTransitioning {
        
        var popStyle: Bool = false
        
        func transitionDuration(
            using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
            return 0.20
        }
        
        func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
            
            if popStyle {
                
                animatePop(using: transitionContext)
                return
            }
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.finalFrame(for: tz)
            
            let fOff = f.offsetBy(dx: f.width, dy: 55)
            tz.view.frame = fOff
            
            transitionContext.containerView.insertSubview(tz.view, aboveSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    tz.view.frame = f
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
        
        func animatePop(using transitionContext: UIViewControllerContextTransitioning) {
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.initialFrame(for: fz)
            let fOffPop = f.offsetBy(dx: f.width, dy: 55)
            
            transitionContext.containerView.insertSubview(tz.view, belowSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    fz.view.frame = fOffPop
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
    }

然后……

2. 在视图控制器中使用它。

注意:奇怪的是，你只需要在“first”视图控制器中这样做。(在“下面”的那个。)

对于你放在上面的那个，什么都不做。一件容易的事。

所以你的班级…

class SomeScreen: UIViewController {
}

变得……

class FrontScreen: UIViewController,
        UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {
    
    let simpleOver = SimpleOver()
    

    override func viewDidLoad() {
        
        super.viewDidLoad()
        navigationController?.delegate = self
    }

    func navigationController(
        _ navigationController: UINavigationController,
        animationControllerFor operation: UINavigationController.Operation,
        from fromVC: UIViewController,
        to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        
        simpleOver.popStyle = (operation == .pop)
        return simpleOver
    }
}

就是这样。

和平常一样，没有变化。推…

let n = UIStoryboard(name: "nextScreenStoryboardName", bundle: nil)
          .instantiateViewController(withIdentifier: "nextScreenStoryboardID")
          as! NextScreen
navigationController?.pushViewController(n, animated: true)

要弹出它，你可以在下一个屏幕中这样做:

class NextScreen: TotallyOrdinaryUIViewController {
    
    @IBAction func userClickedBackOrDismissOrSomethingLikeThat() {
        
        navigationController?.popViewController(animated: true)
    }
}

唷。

@Magnus回答，只有Swift(2.0)才会这样

    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromTop
    self.navigationController!.view.layer.addAnimation(transition, forKey: nil)
    let writeView : WriteViewController = self.storyboard?.instantiateViewControllerWithIdentifier("WriteView") as! WriteViewController
    self.navigationController?.pushViewController(writeView, animated: false)

旁注:

你也可以用Segue做这个，只需要在prepareForSegue或shouldPerformSegueWithIdentifier中实现。但是，这也会保留默认动画。要解决这个问题，你必须转到故事板，单击Segue，取消选中“Animates”框。但这将限制你的应用在IOS 9.0及以上(至少当我在Xcode 7中这样做时)。

在segue中，最后两行应该替换为:

self.navigationController?.popViewControllerAnimated(false)

即使我设为false，它还是会忽略它。

基于jordanperry为swift 4更新的答案

用于推送UIViewController

let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "yourViewController") as! yourViewController
    UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    self.navigationController?.pushViewController(terms, animated: true)
    UIView.setAnimationTransition(.flipFromRight, for: (self.navigationController?.view)!, cache: false)
})

为流行

UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    UIView.setAnimationTransition(.flipFromLeft, for: (self.navigationController?.view)!, cache: false)
})
navigationController?.popViewController(animated: false)

非常简单

self.navigationController?.view.semanticContentAttribute = .forceRightToLeft
