iOS 7 change pushviewcontroller animation direction - ios

Question

When i push a viewcontroller the animation is always from right to left. I want to change that animation to the inverse left to right.
I have tried this code but doesnt work. The animation is still from right to left. How can i achive this simply and correctly? Need help please. Thanks in advance.
//NOT WORKING
myViewController *mController = [self.storyboard instantiateViewControllerWithIdentifier:#"myViewController"];
CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[self.view.layer addAnimation:transition forKey:nil];
[self.navigationController pushViewController:mController animated:YES];

Answer 1

Since this question mentions iOS 7 I'm quite surprised the answer doesn't mention the Animated Transitions API introduced in iOS 7.
If you want to get straight into GitHub the objc.io guys have a great post with a linked project here
Take a look at the documentation and you will see the following:
#availability(iOS, introduced=7.0)
optional func navigationController(navigationController: UINavigationController,
animationControllerForOperation operation: UINavigationControllerOperation,
fromViewController fromVC: UIViewController,
toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning?
Or in Objective-C
- (id <UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
animationControllerForOperation:(UINavigationControllerOperation)operation
fromViewController:(UIViewController *)fromVC
toViewController:(UIViewController *)toVC NS_AVAILABLE_IOS(7_0);
What this means is that from iOS 7 you can control how the navigation controller implements its animations for pushes and pops.
All that is needed is for you to set the delegate of the navigation controller and vend the correct animator object when appropriate. So lets get started:
1. Set the UINavigationControllerDelegate
I typically like to have an App-Wide Navigation Coordinator that manages all my transitions etc. So ideally you want some object that will be alive for the duration of the NavigationController. So we might have a coordinator that looks like this:
class NavigationCoordinationController: NSObject {
private(set) var navigationController:UINavigationController
required init(navigationController: UINavigationController) {
self.navigationController = navigationController
super.init()
navigationController.delegate = self
}
}
I typically create this in the App Delegate so it can be referenced anywhere. You could also set the delegate on a per view controller basis, creating a custom UINavigationController subclass, or wherever you see fit.
2. Create A Custom Animator
Now we need an object that conforms to the UIViewControllerAnimatedTransitioning protocol. This object will be called upon to apply the animation whenever an animated transition is needed. This example is a simple animation that fades and expands the fromView in the transition so its relevant for a Push.
class CustomPushExpansionTransitioner: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
return 1
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let fromView: UIView = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
let toView: UIView = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
let container = transitionContext.containerView()
container.addSubview(toView)
container.bringSubviewToFront(fromView)
toView.frame = container.convertRect(fromView.bounds, fromView: fromView)
UIView.animateWithDuration(transitionDuration(transitionContext),
animations: { () -> Void in
fromView.alpha = 0
fromView.transform = CGAffineTransformConcat(fromView.transform, CGAffineTransformMakeScale(1.3, 1.3))
}) { (complete) -> Void in
transitionContext.completeTransition(true)
}
}
}
3. Vend The Animator Where Necessary
Now we need to implement the UINavigationController delegate and vend our custom animator when needed.
extension NavigationCoordinationController: UINavigationControllerDelegate {
func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
switch operation {
case .Push:
return LaunchToHomeTransitioner()
case .Pop:
break
case .None:
break
}
return nil
}
}
And there you go, you now have total control over your UINavigationController transitions

You are actually doing it right, but as far as I understand from your code, you are not overriding the method:
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
So, you need to inherit from UINavigationController and override the above method.
Here's how I do it (push + pop):
Push:
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
UIView *theWindow = self.view ;
if( animated ) {
CATransition *animation = [CATransition animation];
[animation setDuration:0.45f];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]];
[[theWindow layer] addAnimation:animation forKey:#""];
}
//make sure we pass the super "animated:NO" or we will get both our
//animation and the super's animation
[super pushViewController:viewController animated:NO];
[self swapButtonsForViewController:viewController];
}
Pop :
- (UIViewController *)popViewControllerAnimated:(BOOL)animated {
UIView *theWindow = self.view ;
if( animated ) {
CATransition *animation = [CATransition animation];
[animation setDuration:0.45f];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]];
[[theWindow layer] addAnimation:animation forKey:#""];
}
return [super popViewControllerAnimated:NO];
}

Answer 3

NextViewController *next = [[NextViewController alloc] initWithNibName:#"NextViewController" bundle:nil];
[UIView transitionWithView:self.navigationController.view
duration:0.75
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
[self.navigationController pushViewController:next animated:NO];
}
completion:nil];
Try Above code

Answer 4

You can try this as well.
CATransition *transition = [CATransition animation];
transition.duration = 0.5;
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromLeft;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
DrawingResultsViewController *dr = [DrawingResultsViewController createAndShowProfile:YES];
[self.navigationController pushViewController:dr animated:YES];

Answer 5

If some one is looking for the same answer in Xamarin.iOS (based on gran33 answer) :
public override void PushViewController(UIViewController viewController, bool animated)
{
if (animated)
{
CATransition animation = new CATransition()
{
Duration = 0.5,
Type = CAAnimation.TransitionPush,
Subtype = CAAnimation.TransitionFromTop,
TimingFunction = AMediaTimingFunction.FromName(CAMediaTimingFunction.EaseInEaseOut)
};
View.Layer.AddAnimation(animation, CALayer.Transition);
base.PushViewController(viewController, false);
}
}
public override UIViewController PopViewController(bool animated)
{
if (animated)
{
CATransition animation = new CATransition()
{
Duration = 0.5,
Type = CAAnimation.TransitionPush,
Subtype = CAAnimation.TransitionFromBottom,
TimingFunction = CAMediaTimingFunction.FromName(CAMediaTimingFunction.EaseInEaseOut)
};
View.Layer.AddAnimation(animation, CALayer.Transition);
return base.PopViewController(false);
}
return base.PopViewController(animated);
}

Answer 6

For Swift 4.0+
1 - Create a extension:
extension UINavigationController {
func customPopView(_ viewController: UIViewController) {
let transition: CATransition = CATransition()
transition.duration = 0.3
transition.type = CATransitionType.push
transition.subtype = CATransitionSubtype.fromLeft
view.layer.add(transition, forKey: nil)
pushViewController(viewController, animated: false)
}
}
2 - Call:
self.navigationController?.customPopView(yourViewController)

Answer 7

Assuming myViewController is your view controller, pass custom transition to the nav controller layer.
CATransition *transition = [CATransition animation];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[self.navigationController.view.layer addAnimation:transition forKey:#"pushViewController"];
[self.navigationController pushViewController:myViewController animated:NO];
