How to change the Push and Pop animations in a navigation based app

I did the following and it works fine.. and is simple and easy to understand..

CATransition* transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
//transition.subtype = kCATransitionFromTop; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[[self navigationController] popViewControllerAnimated:NO];

And the same thing for push..


Swift 3.0 version:

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionFade
self.navigationController?.view.layer.add(transition, forKey: nil)
_ = self.navigationController?.popToRootViewController(animated: false)

This is how I've always managed to complete this task.

For Push:

MainView *nextView=[[MainView alloc] init];
[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController:nextView animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[nextView release];

For Pop:

[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];


I still get a lot of feedback from this so I'm going to go ahead and update it to use animation blocks which is the Apple recommended way to do animations anyway.

For Push:

MainView *nextView = [[MainView alloc] init];
[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [self.navigationController pushViewController:nextView animated:NO];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                         }];

For Pop:

[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
                         }];
[self.navigationController popViewControllerAnimated:NO];
