La transition Custom ViewController ne se redimensionne pas correctement

J'ai une Transition Viewcontroller personnalisée pour le controller de navigation dans mon application. Lorsque la transition est effectuée, il n'a pas redimensionné correctement le contenu du viewcontroller enfant. La transition par défaut le redimensionne. J'ai ajouté un exemple de projet sur Github pour démontrer le problème.

Le VC embedded dans le controller de navigation

import UIKit class PopoverVCViewController: UIViewController, UIViewControllerTransitioningDelegate, UINavigationControllerDelegate { let animator = Animator() override func viewDidLoad() { super.viewDidLoad() navigationController?.delegate = self // Do any additional setup after loading the view. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? { animator.reverse = operation == .Pop return animator } }

L'animateur

 class Animator: NSObject, UIViewControllerAnimatedTransitioning { var reverse: Bool = false func animateTransition(transitionContext: UIViewControllerContextTransitioning) { // get reference to our fromView, toView and the container view that we should perform the transition in let container = transitionContext.containerView()! let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)! let toView = transitionContext.viewForKey(UITransitionContextToViewKey)! // set up from 2D transforms that we'll use in the animation let offScreenRight = CGAffineTransformMakeTranslation(container.frame.width, 0) let offScreenLeft = CGAffineTransformMakeTranslation(-container.frame.width, 0) // start the toView to the right of the screen if (self.reverse == false) { toView.transform = offScreenRight } else { toView.transform = offScreenLeft } // add the both views to our view controller container.addSubview(toView) container.addSubview(fromView) // get the duration of the animation // DON'T just type '0.5s' -- the reason why won't make sense until the next post // but for now it's important to just follow this approach let duration = self.transitionDuration(transitionContext) // perform the animation! // for this example, just slid both fromView and toView to the left at the same time // meaning fromView is pushed off the screen and toView slides into view // we also use the block animation usingSpringWithDamping for a little bounce UIView.animateWithDuration(duration, delay: 0.0, usingSpringWithDamping: 1.0, initialSpringVelocity: 0.0, options: UIViewAnimationOptions.CurveEaseInOut, animations: { if (self.reverse == false) { fromView.transform = offScreenLeft } else { fromView.transform = offScreenRight } toView.transform = CGAffineTransformIdentity }, completion: { finished in // tell our transitionContext object that we've finished animating transitionContext.completeTransition(true) }) } // return how many seconds the transiton animation will take func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval { return 0.3 } // MARK: UIViewControllerTransitioningDelegate protocol methods // return the animataor when presenting a viewcontroller // remmeber that an animator (or animation controller) is any object that aheres to the UIViewControllerAnimatedTransitioning protocol func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? { return self } // return the animator used when dismissing from a viewcontroller func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? { return self } }

Vous pouvez définir le cadre de toView pour correspondre à la hauteur et la largeur de fromView :

 let container = transitionContext.containerView()! let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)! let toView = transitionContext.viewForKey(UITransitionContextToViewKey)! toView.frame = CGRectMake(toView.frame.origin.x, toView.frame.origin.y, fromView.frame.width, fromView.frame.height)

ou comme ceci:

 UIViewController* toController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey]; UIViewController* fromController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];

puis configurez ceci vers la fin de votre routine d'animation:

toController.view.frame=fromController.view.frame;
