问题描述
当前,我有一个显示其他视图控制器的视图控制器.我想做的是重新创建推送视图控制器时使用的默认动画.
Currently, I have a view controller presenting other view controller. What I'm trying to do is to recreate the default animation used when pushing a view controller.
我目前的做法是:
FirstViewController
:
@IBAction private func push(sender: AnyObject) {
let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("SecondViewController")
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
view.window?.layer.addAnimation(transition, forKey: kCATransition)
presentViewController(vc, animated: false, completion: nil)
}
SecondViewController
:
@IBAction private func pop(sender: AnyObject) {
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromLeft
view.window?.layer.addAnimation(transition, forKey: kCATransition)
dismissViewControllerAnimated(false, completion: nil)
}
它几乎可以正常工作,但是我有一个奇怪的行为,在视图控制器之间转换时,我有一种黑屏/闪光灯.我已经尝试过更改 window.backgroundColor
,但是它不能解决问题.
It is almost working, but I have a weird behaviour, I'm having a kind of black screen/flash when transitioning between view controllers. I already tried changing window.backgroundColor
but it is not fixing the issue.

推荐答案
问题仅在于您在执行的操作不是如何针对当前/关闭过渡自定义动画.Apple为您提供了一种清晰,完善,正式的方法来执行此操作,而您正在执行的操作并非如此.您需要给呈现的视图控制器一个 transitioningDelegate
以及 animationControllerForPresentedController:
和 animationControllerForDismissedController:
的实现,并实现UIViewControllerAnimatedTransitioning协议,可能还包括一个自定义的UIPresentationController子类.
The trouble is merely that what you're doing is not how to customize the animation for a present/dismiss transition. Apple has provided you with a clear, well-establish, official way to do that, and what you're doing is not it. You need to give your presented view controller a transitioningDelegate
along with implementations of animationControllerForPresentedController:
and animationControllerForDismissedController:
, and implement the UIViewControllerAnimatedTransitioning protocol, possibly along with a custom UIPresentationController subclass.
