我做一个自定义的过渡,如果存在的话动画后,设备将被旋转,然后destinationVC将被解雇,originVC变换是不正确的(未履行屏幕)。如果没有设备旋转,一切工作完全正常。是否有任何人能帮助我吗?
这里是我的现在和解雇动画代码:
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
guard let originViewController = transitionContext.viewController(forKey: .from),
let destinationViewController = transitionContext.viewController(forKey: .to) else { return }
destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
let duration = transitionDuration(using: transitionContext)
UIView.animate(withDuration: duration, animations: {
destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: 0)
originViewController.view.transform = originViewController.view.transform.scaledBy(x: 0.95, y: 0.95)
originViewController.view.layer.cornerRadius = 8.0
}, completion: { completed in
transitionContext.completeTransition(completed)
})
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
guard let originViewController = transitionContext.viewController(forKey: .from),
let destinationViewController = transitionContext.viewController(forKey: .to) else { return }
let duration = transitionDuration(using: transitionContext)
UIView.animate(withDuration: duration, animations: {
originViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
destinationViewController.view.transform = CGAffineTransform.identity
destinationViewController.view.layer.cornerRadius = 0.0
}, completion: { completed in
transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
})
}
编辑:当我添加destinationViewController.view.frame = transitionContext.finalFrame(for: destinationViewController)
解雇动画一切似乎都做工精细,但我不知道这是否是正确的方式
在ViewC1添加一个子视图与领先,顶部,底部,尾随限制。全职工作代码
class ViewC1: UIViewController {
@IBAction func presentNow(_ sender: Any) {
let viewc = storyboard!.instantiateViewController(withIdentifier: "ViewC2") as! ViewC2
viewc.transitioningDelegate = viewc
viewc.modalPresentationStyle = .overCurrentContext
present(viewc, animated: true, completion: nil)
}
}
class ViewC2: UIViewController {
let pres = PresentAnimator()
let diss = DismissAnimator()
@IBAction func dissmisNow(_ sender: Any) {
dismiss(animated: true, completion: nil)
}
}
extension ViewC2: UIViewControllerTransitioningDelegate {
func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return pres
}
func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return diss
}
}
class PresentAnimator: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 1.0
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
guard let originViewController = transitionContext.viewController(forKey: .from),
let destinationViewController = transitionContext.viewController(forKey: .to) else { return }
transitionContext.containerView.addSubview(destinationViewController.view)
destinationViewController.view.frame = transitionContext.containerView.bounds
let originView = originViewController.view.subviews.first
destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
let duration = transitionDuration(using: transitionContext)
UIView.animate(withDuration: duration, animations: {
destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: 0)
originView?.transform = CGAffineTransform(scaleX: 0.95, y: 0.95)
originView?.layer.cornerRadius = 8.0
}, completion: { completed in
transitionContext.completeTransition(completed)
})
}
}
class DismissAnimator: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 1.0
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
guard let originViewController = transitionContext.viewController(forKey: .from),
let destinationViewController = transitionContext.viewController(forKey: .to) else { return }
let originView = destinationViewController.view.subviews.first
let duration = transitionDuration(using: transitionContext)
UIView.animate(withDuration: duration, animations: {
originViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
originView?.transform = CGAffineTransform.identity
originView?.layer.cornerRadius = 0.0
}, completion: { completed in
transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
})
}
}
更新:或者你可以覆盖将旋转和旋转,如果你不希望使用qazxsw POI
view.subviews.first
