记住,在Swift中,扩展绝对是你的朋友!
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: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.popViewControllerAnimated(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: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
self.addTransition(transitionType: type, duration: duration)
self.pushViewController(vc, animated: false)
}
private func addTransition(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
let transition = CATransition()
transition.duration = duration
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = type
self.view.layer.addAnimation(transition, forKey: nil)
}
}

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];
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)
基于jordanperry为swift 4更新的答案
用于推送UIViewController
let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "yourViewController") as! yourViewController
UIView.animate(withDuration: 0.75, animations: {() -> Void in
UIView.setAnimationCurve(.easeInOut)
self.navigationController?.pushViewController(terms, animated: true)
UIView.setAnimationTransition(.flipFromRight, for: (self.navigationController?.view)!, cache: false)
})
为流行
UIView.animate(withDuration: 0.75, animations: {() -> Void in
UIView.setAnimationCurve(.easeInOut)
UIView.setAnimationTransition(.flipFromLeft, for: (self.navigationController?.view)!, cache: false)
})
navigationController?.popViewController(animated: false)
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。
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)
}
