我有一个基于导航的应用程序,我想改变推送和弹出动画的动画。我该怎么做呢?

这个问题有很多答案,现在已经有很长一段时间了,我重新选择了我认为最相关的答案。如果有人有不同的想法,请在评论中告诉我


当前回答

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;
}

其他回答

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。
