有UINavigationControllerDelegate和uiviewcontrolleranimatedtransiating你可以改变任何你想要的动画。

例如，这是VC的垂直流行动画:

@objc class PopAnimator: NSObject, UIViewControllerAnimatedTransitioning {

func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
    return 0.5
}

func animateTransition(transitionContext: UIViewControllerContextTransitioning) {

    let fromViewController = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
    let toViewController = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
    let containerView = transitionContext.containerView()
    let bounds = UIScreen.mainScreen().bounds
    containerView!.insertSubview(toViewController.view, belowSubview: fromViewController.view)
    toViewController.view.alpha = 0.5

    let finalFrameForVC = fromViewController.view.frame

    UIView.animateWithDuration(transitionDuration(transitionContext), animations: {
        fromViewController.view.frame = CGRectOffset(finalFrameForVC, 0, bounds.height)
        toViewController.view.alpha = 1.0
        }, completion: {
            finished in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
    })
}

}

然后

func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    if operation == .Pop {
        return PopAnimator()
    }
    return nil;
}

有用的教程 https://www.objc.io/issues/5-ios7/view-controller-transitions/

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];
    }];
}

为推动

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:ViewControllerYouWantToPush animated:NO];

为流行

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];

虽然这里所有的答案都很棒，而且大多数工作得很好，但有一个稍微简单一点的方法可以达到同样的效果……

推动:

  NextViewController *nextViewController = [[NextViewController alloc] init];

  // Shift the view to take the status bar into account 
  CGRect frame = nextViewController.view.frame;
  frame.origin.y -= 20;
  frame.size.height += 20;
  nextViewController.view.frame = frame;

  [UIView transitionFromView:self.navigationController.topViewController.view toView:nextViewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromRight completion:^(BOOL finished) {
    [self.navigationController pushViewController:nextViewController animated:NO];
  }];

流行:

  int numViewControllers = self.navigationController.viewControllers.count;
  UIView *nextView = [[self.navigationController.viewControllers objectAtIndex:numViewControllers - 2] view];

  [UIView transitionFromView:self.navigationController.topViewController.view toView:nextView duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
    [self.navigationController popViewControllerAnimated:NO];
  }];}

你现在可以使用uiview。transition。注意animated:false。这适用于任何转换选项，弹出，推或堆栈替换。

if let nav = self.navigationController
{
    UIView.transition(with:nav.view, duration:0.3, options:.transitionCrossDissolve, animations: {
        _ = nav.popViewController(animated:false)
    }, completion:nil)
}

意识到这是一个老问题。我仍然想张贴这个答案，因为我有一些问题弹出几个viewcontroller与建议的答案。我的解决方案是子类UINavigationController和覆盖所有的弹出和推方法。
