看看ADTransitionController,用自定义过渡动画替换UINavigationController(它的API与UINavigationController的API匹配),这是我们在Applidium创建的。
您可以使用不同的预定义动画推送和弹出动作,如滑动,淡出,立方体,旋转,缩放等。

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];
}];}
I found a mildly recursive way to do this that works for my purposes. I have an instance variable BOOL that I use to block the normal popping animation and substitute my own non-animated pop message. The variable is initially set to NO. When the back button is tapped, the delegate method sets it to YES and sends a new non-animated pop message to the nav bar, thereby calling the same delegate method again, this time with the variable set to YES. With the variable is set to YES, the delegate method sets it to NO and returns YES to allow the non-animated pop occur. After the second delegate call returns, we end up back in the first one, where NO is returned, blocking the original animated pop! It's actually not as messy as it sounds. My shouldPopItem method looks like this:
- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
{
if ([[navigationBar items] indexOfObject:item] == 1)
{
[expandedStack restack];
}
if (!progPop)
{
progPop = YES;
[navBar popNavigationItemAnimated:NO];
return NO;
}
else
{
progPop = NO;
return YES;
}
}
对我有用。

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。
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)
