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;
}

使用私人通话是一个坏主意,因为苹果不再批准这样做的应用程序。 也许你可以试试这个:
//Init Animation
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: 0.50];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:YES];
//Create ViewController
MyViewController *myVC = [[MyViewController alloc] initWith...];
[self.navigationController pushViewController:myVC animated:NO];
[myVC release];
//Start Animation
[UIView commitAnimations];
这就是我总是设法完成这项任务的方法。
推动:
MainView *nextView=[[MainView alloc] init];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController:nextView animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[nextView release];
流行:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelay:0.375];
[self.navigationController popViewControllerAnimated:NO];
[UIView commitAnimations];
我还是从这里得到了很多反馈所以我将继续更新它,使用动画块这是苹果推荐的制作动画的方法。 推动:
MainView *nextView = [[MainView alloc] init];
[UIView animateWithDuration:0.75
animations:^{
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[self.navigationController pushViewController:nextView animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
}];
流行:
[UIView animateWithDuration:0.75
animations:^{
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
}];
[self.navigationController popViewControllerAnimated:NO];
以下是我如何在Swift中做同样的事情:
推动:
UIView.animateWithDuration(0.75, animations: { () -> Void in
UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
self.navigationController!.pushViewController(nextView, animated: false)
UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromRight, forView: self.navigationController!.view!, cache: false)
})
流行:
实际上,我对上面的一些回答做了一些不同的处理——但由于我是Swift开发的新手,这可能是不对的。我重写了viewWillDisappear:animated:,并在那里添加了弹出代码:
UIView.animateWithDuration(0.75, animations: { () -> Void in
UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromLeft, forView: self.navigationController!.view, cache: false)
})
super.viewWillDisappear(animated)
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];
}];
}
从示例应用程序中,可以看到这种变化。 https://github.com/mpospese/MPFoldTransition/
#pragma mark - UINavigationController(MPFoldTransition)
@implementation UINavigationController(MPFoldTransition)
//- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
- (void)pushViewController:(UIViewController *)viewController foldStyle:(MPFoldStyle)style
{
[MPFoldTransition transitionFromViewController:[self visibleViewController]
toViewController:viewController
duration:[MPFoldTransition defaultDuration]
style:style
completion:^(BOOL finished) {
[self pushViewController:viewController animated:NO];
}
];
}
- (UIViewController *)popViewControllerWithFoldStyle:(MPFoldStyle)style
{
UIViewController *toController = [[self viewControllers] objectAtIndex:[[self viewControllers] count] - 2];
[MPFoldTransition transitionFromViewController:[self visibleViewController]
toViewController:toController
duration:[MPFoldTransition defaultDuration]
style:style
completion:^(BOOL finished) {
[self popViewControllerAnimated:NO];
}
];
return toController;
}
