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

@Luca Davanzo的答案在Swift 4.2

public extension UINavigationController {

    /**
     Pop current view controller to previous view controller.

     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func pop(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.popViewController(animated: false)
    }

    /**
     Push a new view controller on the view controllers's stack.

     - parameter vc:       view controller to push.
     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func push(viewController vc: UIViewController, transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.pushViewController(vc, animated: false)
    }

    private func addTransition(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        transition.type = type
        self.view.layer.add(transition, forKey: nil)
    }

}

其他回答

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)
}

我知道这个帖子很旧了,但我想我应该发表我的意见。你不需要制作一个自定义动画,有一个简单(可能是hack)的方法来做它。不使用push,而是创建一个新的导航控制器,使新的视图控制器成为那个nav控制器的根视图控制器,然后从原始的nav控制器中呈现出nav控制器。现在是很容易自定义的许多风格,不需要做一个自定义动画。

例如:

UIViewcontroller viewControllerYouWantToPush = UIViewController()
UINavigationController newNavController = UINavigationController(root: viewControllerYouWantToView)
newNavController.navBarHidden = YES;
self.navigationController.present(newNavController)

你可以随心所欲地改变演示风格。

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。

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];

使用iJordan的答案作为灵感,为什么不简单地在UINavigationController上创建一个Category来在整个应用程序中使用,而不是复制/粘贴这个动画代码的所有地方?

UINavigationController + Animation.h

@interface UINavigationController (Animation)

- (void) pushViewControllerWithFlip:(UIViewController*) controller;

- (void) popViewControllerWithFlip;

@end

UINavigationController+Animation.m

@implementation UINavigationController (Animation)

- (void) pushViewControllerWithFlip:(UIViewController *) controller
{
    [UIView animateWithDuration:0.50
                     animations:^{
                         [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                         [self pushViewController:controller animated:NO];
                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:NO];
                     }];
}

- (void) popViewControllerWithFlip
{
    [UIView animateWithDuration:0.5
                     animations:^{
                         [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:NO];
                     }];

    [self popViewControllerAnimated:NO];
}

@end

然后简单地导入UINavigationController+Animation.h文件并正常调用它:

[self.navigationController pushViewControllerWithFlip:[[NewViewController alloc] init]];

[self.navigationController popViewControllerWithFlip];
