@Magnus回答,只有Swift(2.0)才会这样
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromTop
self.navigationController!.view.layer.addAnimation(transition, forKey: nil)
let writeView : WriteViewController = self.storyboard?.instantiateViewControllerWithIdentifier("WriteView") as! WriteViewController
self.navigationController?.pushViewController(writeView, animated: false)
旁注:
你也可以用Segue做这个,只需要在prepareForSegue或shouldPerformSegueWithIdentifier中实现。但是,这也会保留默认动画。要解决这个问题,你必须转到故事板,单击Segue,取消选中“Animates”框。但这将限制你的应用在IOS 9.0及以上(至少当我在Xcode 7中这样做时)。
在segue中,最后两行应该替换为:
self.navigationController?.popViewControllerAnimated(false)
即使我设为false,它还是会忽略它。
其他回答
@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)
}
}
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。
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];
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)
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。
