iphone - Animate presentModalViewController de derecha/izquierda

presentviewcontroller animated completion

Question

Actualmente estoy usando [self presentModalViewController :newVC animated:YES] . Deseo presentar newViewcontroller desde la izquierda / derecha / arriba / abajo con un efecto push. Traté de usar CATransition pero muestra una pantalla en negro entre la transición.

Answer 1

Cuando está presente:

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];
[self presentModalViewController:viewCtrl animated:NO];

Cuando descarte:

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[self.view.window.layer addAnimation:transition forKey:nil];
[self dismissModalViewControllerAnimated:NO];

Answer 2

Después de X> = 4 horas de trabajo, esto funciona sin "rasgar" u otros artefactos de fondo:

class AboutTransition: NSObject, UIViewControllerAnimatedTransitioning {
let presenting: Bool
let duration: NSTimeInterval
init(presenting: Bool, duration: NSTimeInterval = 0.25) {
self.presenting = presenting
self.duration = duration
}
@objc func transitionDuration(ctx: UIViewControllerContextTransitioning) -> NSTimeInterval {
return duration
}
@objc func animateTransition(ctx: UIViewControllerContextTransitioning) {
let duration = transitionDuration(ctx)
let containerView = ctx.containerView()
let fromViewController = ctx.viewControllerForKey(UITransitionContextFromViewControllerKey)!
let toViewController = ctx.viewControllerForKey(UITransitionContextToViewControllerKey)!
let fromView = fromViewController.view // 7.0 & 8.0 compatible vs. viewForKey:
let toView = toViewController.view // 7.0 & 8.0 compatible vs. viewForKey:
containerView.addSubview(fromView)
containerView.addSubview(toView)
let offScreenRight = CGAffineTransformMakeTranslation(containerView.frame.width, 0)
let offScreenLeft = CGAffineTransformMakeTranslation(-containerView.frame.width, 0)
fromView.transform = CGAffineTransformIdentity
toView.transform = self.presenting ? offScreenRight : offScreenLeft
UIView.animateWithDuration(duration, delay:0, options:UIViewAnimationOptions(0), animations: {
fromView.transform = self.presenting ? offScreenLeft : offScreenRight
toView.transform = CGAffineTransformIdentity
}, completion: { (finished: Bool) in
ctx.completeTransition(finished)
if finished {
fromView.removeFromSuperview()
fromView.frame = toView.frame // reset the frame for reuse, otherwise frame transforms will accumulate
}
})
}
}

Luego, en AppDelegate.swift :

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UINavigationControllerDelegate {
lazy var window: UIWindow? = {
return UIWindow(frame: UIScreen.mainScreen().bounds)
}()
lazy var storyboard = UIStoryboard(name: "Main", bundle: nil)
lazy var nav: UINavigationController = {
var r = self.storyboard.instantiateInitialViewController() as! UINavigationController
r.delegate = self
return r
}()
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
self.window!.rootViewController = nav
self.window!.makeKeyAndVisible()
// .. other setup
return true
}
// ...
// MARK: - UINavigationControllerDelegate
func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
// Example of a SettingsViewController which pushes AboutViewController
if fromVC is SettingsViewController && toVC is AboutViewController { // Push to About
return AboutTransition(presenting: true)
} else if fromVC is AboutViewController && toVC is SettingsViewController { // Pop to Settings
return AboutTransition(presenting: false)
}
return nil
}
}

Esto supone que una aplicación está utilizando el guión gráfico predeterminado con un VC inicial como un UINavigationController

Actualización para swift 3/4

class LTRTransition: NSObject, UIViewControllerAnimatedTransitioning
{
let presenting: Bool
let duration: TimeInterval
init(presenting: Bool, duration: TimeInterval = Theme.currentTheme.animationDuration) {
self.presenting = presenting
self.duration = duration
}
@objc func transitionDuration(using ctx: UIViewControllerContextTransitioning?) -> TimeInterval {
return duration
}
@objc func animateTransition(using ctx: UIViewControllerContextTransitioning) {
let duration = transitionDuration(using: ctx)
let containerView = ctx.containerView
let fromViewController = ctx.viewController(forKey: UITransitionContextViewControllerKey.from)!
let toViewController = ctx.viewController(forKey: UITransitionContextViewControllerKey.to)!
guard let fromView = fromViewController.view, // 7.0 & 8.0 compatible vs. viewForKey:
let toView = toViewController.view // 7.0 & 8.0 compatible vs. viewForKey:
else {
assertionFailure("fix this")
return
}
containerView.addSubview(fromView)
containerView.addSubview(toView)
let offScreenRight = CGAffineTransform(translationX: containerView.frame.width, y: 0)
let offScreenLeft = CGAffineTransform(translationX: -containerView.frame.width, y: 0)
fromView.transform = CGAffineTransform.identity
toView.transform = self.presenting ? offScreenRight : offScreenLeft
UIView.animate(withDuration: duration, delay:0, options:UIViewAnimationOptions(rawValue: 0), animations: {
fromView.transform = self.presenting ? offScreenLeft : offScreenRight
toView.transform = CGAffineTransform.identity
}, completion: { (finished: Bool) in
ctx.completeTransition(finished)
if finished {
fromView.removeFromSuperview()
// this screws up dismissal. at least on ios10 it does fromView.frame = toView.frame // reset the frame for reuse, otherwise frame transforms will accumulate
}
})
}
}

Y la implementación transitioniningDelegate para el VC se empuja / descarta:

extension WhateverVCyouArePresentingFrom: UIViewControllerTransitioningDelegate
{
public func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning?
{
return LTRTransition(presenting: true)
}
public func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning?
{
return LTRTransition(presenting: false)
}
}

Answer 3

Puede establecer un transitioningDelegate de transitioningDelegate en el controlador de vista que desea presentar. Debe cumplir con los protocolos UIViewControllerTransitioningDelegate y UIViewControllerAnimatedTransitioning . Y al implementar animateTransition(transitionContext: UIViewControllerContextTransitioning) puede animar cualquiera de las subvistas de los controladores de vista.

Función que realiza la transición

class fromViewController : UIViewController {
let transitionManager = TransitionManager()
func transitionToViewController() {
toController.transitioningDelegate = transitionManager
presentViewController(toController, animated: true, completion: nil)
}
}

Entonces, el TransitionManager se ve así:

import UIKit
class TransitionManager : UIPercentDrivenInteractiveTransition {
var presenting = false
}
// MARK: UIViewControllerAnimatedTransitioning
extension TransitionManager : UIViewControllerAnimatedTransitioning {
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let container = transitionContext.containerView()
let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)!
let toView = transitionContext.viewForKey(UITransitionContextToViewKey)!
let offScreenRight = CGAffineTransformMakeTranslation(container.frame.width, 0)
let offScreenLeft = CGAffineTransformMakeTranslation(-container.frame.width, 0)
toView.transform = self.presenting ? offScreenRight : offScreenLeft
container.addSubview(toView)
container.addSubview(fromView)
let duration = self.transitionDuration(transitionContext)
UIView.animateWithDuration(duration, delay: 0.0, usingSpringWithDamping: 1, initialSpringVelocity: 0.8, options: nil, animations: {
fromView.transform = self.presenting ? offScreenLeft : offScreenRight
toView.transform = CGAffineTransformIdentity
}, completion: { finished in
transitionContext.completeTransition(true)
})
}
func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
return 0.3
}
}
// MARK: UIViewControllerTransitioningDelegate
extension TransitionManager : UIViewControllerTransitioningDelegate {
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
self.presenting = true
return self
}
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
self.presenting = false
return self
}
}

Answer 4

Solo hay cuatro UIModalTransitionStyles:

UIModalTransitionStyleCoverVertical
UIModalTransitionStyleFlipHorizontal
UIModalTransitionStyleCrossDissolve
UIModalTransitionStylePartialCurl

Por ejemplo:

UIViewController *controller = [[[MyViewController alloc] init] autorelease];
UIModalTransitionStyle trans = UIModalTransitionStyleFlipHorizontal;
[UIView beginAnimations: nil context: nil];
[UIView setAnimationTransition: trans forView: [self window] cache: YES];
[navController presentModalViewController: controller animated: NO];
[UIView commitAnimations];

Answer 5

Yo tuve el mismo problema. Supongamos que desea presentar un controlador de vista 2 desde el controlador de vista 1. En el primer uso de controlador de vista

 [self presentModalViewController: controller animated: NO]];

En el controlador de la segunda vista, en el método viewWillAppear: agregue el código

 CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setDuration:0.40];
[animation setTimingFunction:
[CAMediaTimingFunction functionWithName:
kCAMediaTimingFunctionEaseInEaseOut]];
[self.view.layer addAnimation:animation forKey:kCATransition];

Funcionará bien. Si aparece una pantalla negra nuevamente, si está usando el controlador de navegación, reemplace

 [self.view.layer addAnimation:animation forKey:kCATransition];

con

 [self.navigationController.view.layer addAnimation:animation forKey:kCATransition];
