UINavigationController: pop view controller in the opposite direction

Question

I'm trying to call [[self navigationController] popViewControllerAnimated:YES] but making the animation slide right to left instead of left to right. Any easy way to do this? I want to return to the previous view. Any help is appreciated. Thanks!

It is possible, look at the following code I used a while back and try to make it work for yourself. Yu only need to change the setAnimationTransition

[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelay:0.375];
[self.navigationController popViewControllerAnimated:NO];
[UIView commitAnimations];

There are a few different kind of default animations to use, apples site says this kind of animations are possible:

typedef enum {
   UIViewAnimationTransitionNone,
   UIViewAnimationTransitionFlipFromLeft,
   UIViewAnimationTransitionFlipFromRight,
   UIViewAnimationTransitionCurlUp,
   UIViewAnimationTransitionCurlDown,
} UIViewAnimationTransition;

So in your case you would want to use the following:

    [UIView  beginAnimations:nil context:nil];
    [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.75];
    [self.navigationController popViewControllerAnimated:NO];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
    [UIView commitAnimations];

Thanks. Is there a way to slide it as if you were calling pushViewController? – Solenoid

Yes like i said, you only need to change the line here: [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; – Dynatron

I understand that. I can't find the correct transition though. – Solenoid

It's just that none of those do what I want them to do. I want it to have exactly the same motion as if the UINavigationController was pushing a new view controller – Solenoid

It does, i will edit my post to make this animation, this will be exactly what you want. – Dynatron

Your solution does something weird. It pops the view without any animation but only the title on the Navigation Bar slides in, not the view itself. Thoughts? – Solenoid

I don't know what your code is, but basically what i did there is exactly what you want to use, try to edit it to your own code. – Dynatron

Did not. That's okay, though, I ended up going with a different UI strategy. Thanks for the help! Will accept your answer so you can get the points. – Solenoid

This is how one can pop view controller in opposite direction. Its working for me 100%

CATransition *transition = [CATransition animation];
    transition.duration = 0.45;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];
    transition.type = kCATransitionFromRight;
    [transition setType:kCATransitionPush];
    transition.subtype = kCATransitionFromRight;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    [self.navigationController popViewControllerAnimated:NO];

You set the type twice? transition.type = kCATransitionPush should be enough. – Ebro

Answer 3

Swift version:

    let animation = CATransition()
    animation.duration = 0.3
    animation.type = .push
    animation.subtype = .fromRight
    animation.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
    navigationController?.view.layer.add(animation, forKey: nil)
    navigationController?.popViewController(animated: false)
