@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)
    }

}

我做了以下工作，它很好..并且简单易懂。

CATransition* transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
//transition.subtype = kCATransitionFromTop; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[[self navigationController] popViewControllerAnimated:NO];

push也是一样。

Swift 3.0版本:

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionFade
self.navigationController?.view.layer.add(transition, forKey: nil)
_ = self.navigationController?.popToRootViewController(animated: false)

我最近也在尝试做类似的事情。我决定我不喜欢UINavigationController的滑动动画，但我也不想做UIView给你的动画，比如旋度之类的。我想做一个交叉淡出之间的观点，当我推或弹出。

The problem there involves the fact that the view is literally removing the view or popping one over the top of the current one, so a fade doesn't work. The solution I came to involved taking my new view and adding it as a subview to the current top view on the UIViewController's stack. I add it with an alpha of 0, then do a crossfade. When the animation sequence finishes, I push the view onto the stack without animating it. I then go back to the old topView and clean up stuff that I had changed.

它比这稍微复杂一点，因为你有navigationItems，你必须调整，使过渡看起来正确。此外，如果你做任何旋转，你必须调整帧的大小，因为你添加的视图作为子视图，使他们正确地显示在屏幕上。下面是我使用的一些代码。我子类化了UINavigationController并覆盖了push和pop方法。

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
      UIViewController *currentViewController = [self.viewControllers lastObject];
      //if we don't have a current controller, we just do a normal push
      if(currentViewController == nil)
      {
         [super pushViewController:viewController animated:animated];
         return;
      }
      //if no animation was requested, we can skip the cross fade
      if(!animation)
      {
         [super pushViewController:viewController animated:NO];
         return;
      }
      //start the cross fade.  This is a tricky thing.  We basically add the new view
//as a subview of the current view, and do a cross fade through alpha values.
//then we push the new view on the stack without animating it, so it seemlessly is there.
//Finally we remove the new view that was added as a subview to the current view.

viewController.view.alpha = 0.0;
//we need to hold onto this value, we'll be releasing it later
    NSString *title = [currentViewController.title retain];

//add the view as a subview of the current view
[currentViewController.view addSubview:viewController.view];
[currentViewController.view bringSubviewToFront:viewController.view];
UIBarButtonItem *rButtonItem = currentViewController.navigationItem.rightBarButtonItem;
UIBarButtonItem *lButtonItem = currentViewController.navigationItem.leftBarButtonItem;

NSArray *array = nil;

//if we have a right bar button, we need to add it to the array, if not, we will crash when we try and assign it
//so leave it out of the array we are creating to pass as the context.  I always have a left bar button, so I'm not checking to see if it is nil. Its a little sloppy, but you may want to be checking for the left BarButtonItem as well.
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,nil];
}

//remove the right bar button for our transition
[currentViewController.navigationItem setRightBarButtonItem:nil animated:YES];
//remove the left bar button and create a backbarbutton looking item
//[currentViewController.navigationItem setLeftBarButtonItem:nil animated:NO];

//set the back button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:title style:kButtonStyle target:self action:@selector(goBack)];
[currentViewController.navigationItem setLeftBarButtonItem:backButton animated:YES];
[viewController.navigationItem setLeftBarButtonItem:backButton animated:NO];
[backButton release];

[currentViewController setTitle:viewController.title];

[UIView beginAnimations:@"push view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePushDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[viewController.view setAlpha: 1.0];
[UIView commitAnimations];
}

-(void)animationForCrossFadePushDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{

UIViewController *c = [(NSArray*)context objectAtIndex:0];
UIViewController *n = [(NSArray*)context objectAtIndex:1];
NSString *title     = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:3];
UIBarButtonItem *r = nil;
//not all views have a right bar button, if we look for it and it isn't in the context,
//we'll crash out and not complete the method, but the program won't crash.
//So, we need to check if it is there and skip it if it isn't.
if([(NSArray *)context count] == 5)
    r = [(NSArray *)context objectAtIndex:4];

//Take the new view away from being a subview of the current view so when we go back to it
//it won't be there anymore.
[[[c.view subviews] lastObject] removeFromSuperview];
[c setTitle:title];
[title release];
//set the search button
[c.navigationItem setLeftBarButtonItem:l animated:NO];
//set the next button
if(r != nil)
    [c.navigationItem setRightBarButtonItem:r animated:NO];


[super pushViewController:n animated:NO];

 }

正如我在代码中提到的，我总是有一个左栏按钮项，所以在把它放在作为动画委托上下文传递的数组中之前，我不检查它是否为nil。如果你这样做，你可能想要检查一下。

我发现的问题是，如果你在委托方法中崩溃，它不会崩溃程序。它只是阻止委托完成但你不会得到任何警告。 因为我在那个委派例程中做清理，它引起了一些奇怪的视觉行为，因为它没有完成清理。

我创建的后退按钮调用一个“goBack”方法，该方法只调用pop例程。

-(void)goBack
{ 
     [self popViewControllerAnimated:YES];
}

还有，这是我的流行曲目。

-(UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    //get the count for the number of viewControllers on the stack
int viewCount = [[self viewControllers] count];
//get the top view controller on the stack
UIViewController *topViewController = [self.viewControllers objectAtIndex:viewCount - 1];
//get the next viewController after the top one (this will be the new top one)
UIViewController *newTopViewController = [self.viewControllers objectAtIndex:viewCount - 2];

//if no animation was requested, we can skip the cross fade
if(!animated)
{
    [super popViewControllerAnimated:NO];
            return topViewController;
}



//start of the cross fade pop.  A bit tricky.  We need to add the new top controller
//as a subview of the curent view controler with an alpha of 0.  We then do a cross fade.
//After that we pop the view controller off the stack without animating it.
//Then the cleanup happens: if the view that was popped is not released, then we
//need to remove the subview we added and change some titles back.
newTopViewController.view.alpha = 0.0;
[topViewController.view addSubview:newTopViewController.view];
[topViewController.view bringSubviewToFront:newTopViewController.view];
NSString *title = [topViewController.title retain];
UIBarButtonItem *lButtonItem = topViewController.navigationItem.leftBarButtonItem;
UIBarButtonItem *rButtonItem = topViewController.navigationItem.rightBarButtonItem;

//set the new buttons on top of the current controller from the new top controller
if(newTopViewController.navigationItem.leftBarButtonItem != nil)
{
    [topViewController.navigationItem setLeftBarButtonItem:newTopViewController.navigationItem.leftBarButtonItem animated:YES];
}
if(newTopViewController.navigationItem.rightBarButtonItem != nil)
{
    [topViewController.navigationItem setRightBarButtonItem:newTopViewController.navigationItem.rightBarButtonItem animated:YES];
}

[topViewController setTitle:newTopViewController.title];
//[topViewController.navigationItem.leftBarButtonItem setTitle:newTopViewController.navigationItem.leftBarButtonItem.title];

NSArray *array = nil;
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,nil];
}


[UIView beginAnimations:@"pop view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePopDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[newTopViewController.view setAlpha: 1.0];
[UIView commitAnimations];
return topViewController;

 }

 -(void)animationForCrossFadePopDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
 {

UIViewController *c = [(NSArray *)context objectAtIndex:0];
//UIViewController *n = [(NSArray *)context objectAtIndex:1];
NSString *title = [(NSArray *)context objectAtIndex:1];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *r = nil;



//Not all views have a right bar button.  If we look for one that isn't there
// we'll crash out and not complete this method, but the program will continue.
//So we need to check if it is therea nd skip it if it isn't.
if([(NSArray *)context count] == 4)
    r = [(NSArray *)context objectAtIndex:3];

//pop the current view from the stack without animation
[super popViewControllerAnimated:NO];

//if what was the current veiw controller is not nil, then lets correct the changes
//we made to it.
if(c != nil)
{
    //remove the subview we added for the transition
    [[c.view.subviews lastObject] removeFromSuperview];
    //reset the title we changed
    c.title = title;
    [title release];
    //replace the left bar button that we changed
    [c.navigationItem setLeftBarButtonItem:l animated:NO];
    //if we were passed a right bar button item, replace that one as well
    if(r != nil)
        [c.navigationItem setRightBarButtonItem:r animated:NO];
    else {
        [c.navigationItem setRightBarButtonItem:nil animated:NO];
    }


 }
}

That's pretty much it. You'll need some additional code if you want to implement rotations. You'll need to set the frame size of your views that you add as subviews before you show them otherwise you'll run into issues the orientation is landscape, but the last time you saw the previous view it was portrait. So, then you add it as a sub view and fade it in but it shows up as portrait, then when we pop without animation, the same view, but the one that is in the stack, now is landscape. The whole thing looks a little funky. Everyone's implementation of rotation is a little different so I didn't include my code for that here.

希望它能帮助到一些人。我到处都在找这样的东西，但什么也没找到。我不认为这是完美的答案，但在这一点上，它对我来说真的很有效。

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)
    }

}

请参阅我对这个问题的回答，以了解如何用更少的代码行完成它。这个方法允许你以任何你喜欢的方式动画一个新视图控制器的伪“Push”，当动画完成时，它就像你使用标准的Push方法一样设置导航控制器。我的示例允许您从左边或从右边对滑入进行动画操作。 为了方便起见，这里重复了代码:

-(void) showVC:(UIViewController *) nextVC rightToLeft:(BOOL) rightToLeft {
    [self addChildViewController:neighbor];
    CGRect offscreenFrame = self.view.frame;
    if(rightToLeft) {
        offscreenFrame.origin.x = offscreenFrame.size.width * -1.0;
    } else if(direction == MyClimbDirectionRight) {
        offscreenFrame.origin.x = offscreenFrame.size.width;
    }
    [[neighbor view] setFrame:offscreenFrame];
    [self.view addSubview:[neighbor view]];
    [neighbor didMoveToParentViewController:self];
    [UIView animateWithDuration:0.5 animations:^{
        [[neighbor view] setFrame:self.view.frame];
    } completion:^(BOOL finished){
        [neighbor willMoveToParentViewController:nil];
        [neighbor.view removeFromSuperview];
        [neighbor removeFromParentViewController];
        [[self navigationController] pushViewController:neighbor animated:NO];
        NSMutableArray *newStack = [[[self navigationController] viewControllers] mutableCopy];
        [newStack removeObjectAtIndex:1]; //self, just below top
        [[self navigationController] setViewControllers:newStack];
    }];
}

@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。
