@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];
