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;
}

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;
}
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];
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。
翻转导航控制器.h
@interface FlippingNavigationController : UINavigationController
@end
FlippingNavigationController.m:
#import "FlippingNavigationController.h"
#define FLIP_DURATION 0.5
@implementation FlippingNavigationController
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[UIView transitionWithView:self.view
duration:animated?FLIP_DURATION:0
options:UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionTransitionFlipFromRight
animations:^{ [super pushViewController:viewController
animated:NO]; }
completion:nil];
}
- (UIViewController *)popViewControllerAnimated:(BOOL)animated
{
return [[self popToViewController:[self.viewControllers[self.viewControllers.count - 2]]
animated:animated] lastObject];
}
- (NSArray *)popToRootViewControllerAnimated:(BOOL)animated
{
return [self popToViewController:[self.viewControllers firstObject]
animated:animated];
}
- (NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated
{
__block NSArray* viewControllers = nil;
[UIView transitionWithView:self.view
duration:animated?FLIP_DURATION:0
options:UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionTransitionFlipFromLeft
animations:^{ viewControllers = [super popToViewController:viewController animated:NO]; }
completion:nil];
return viewControllers;
}
@end
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)
}
我不知道有什么方法可以公开更改过渡动画。
如果“后退”按钮不是必需的,你应该使用模态视图控制器来实现“push from bottom”/“flip”/“fade”/(≥3.2)“页面卷曲”过渡。
在私有端,方法-pushViewController:animated:调用未记录的方法-pushViewController:transition:forceImmediate:,因此,例如,如果你想要一个从左到右的翻转转换,你可以使用
[navCtrler pushViewController:ctrler transition:10 forceImmediate:NO];
但是,您不能以这种方式更改“pop”过渡。
