Я пытаюсь добиться чего-то вроде следующего открытия бокового меню из tabbar
нажатия элемента.
Я использовал следующий класс для перехода Анимация ...
class SlideInTransition: NSObject, UIViewControllerAnimatedTransitioning {
var isPresenting = false
let dimmingView = UIView()
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 3
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
guard let toViewController = transitionContext.viewController(forKey: .to),
let fromViewController = transitionContext.viewController(forKey: .from) else { return }
let containerView = transitionContext.containerView
let finalWidth = toViewController.view.bounds.width * 0.3
let finalHeight = toViewController.view.bounds.height
if isPresenting {
// Add dimming view
dimmingView.backgroundColor = .black
dimmingView.alpha = 0.0
containerView.addSubview(dimmingView)
dimmingView.frame = containerView.bounds
// Add menu view controller to container
containerView.addSubview(toViewController.view)
// Init frame off the screen
toViewController.view.frame = CGRect(x: -finalWidth, y: 0, width: finalWidth, height: finalHeight)
}
// Move on screen
let transform = {
self.dimmingView.alpha = 0.5
toViewController.view.transform = CGAffineTransform(translationX: finalWidth, y: 0)
}
// Move back off screen
let identity = {
self.dimmingView.alpha = 0.0
fromViewController.view.transform = .identity
}
// Animation of the transition
let duration = transitionDuration(using: transitionContext)
let isCancelled = transitionContext.transitionWasCancelled
UIView.animate(withDuration: duration, animations: {
self.isPresenting ? transform() : identity()
}) { (_) in
transitionContext.completeTransition(!isCancelled)
}
}
}
и используйте ее в моем коде следующим образом
guard let menuViewController = storyboard?.instantiateViewController(withIdentifier: "MenuVC") as? MenuVC else { return }
menuViewController.modalPresentationStyle = .overCurrentContext
menuViewController.transitioningDelegate = self as? UIViewControllerTransitioningDelegate
menuViewController.tabBarItem.image = UIImage(named: "ico_menu")
menuViewController.tabBarItem.selectedImage = UIImage(named: "ico_menu")
viewControllers = [orderVC,serverdVC,canceledVC,menuViewController]
extension TabbarVC: UIViewControllerTransitioningDelegate {
func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
transiton.isPresenting = true
return transiton
}
func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
transiton.isPresenting = false
return transiton
}
}
, но анимация вообще не работает ... Я хочу открыть ее как боковое меню поверх текущий контекст ..
Как мне достичь чего-то подобного ...
