Custom action on Back Button UINavigationController

by Hans Pinckaers

Yes! There is a way of using the backBarButton with a custom action. No, it’s not by overriding the backBarButton property of navigationItem. This is not an ugly solution with images that simulate the “Back”-button (arrow-shaped.) It’s possible to use the backBarButton for popping the current viewController as normal, but for example with other animations such as UIViewAnimationTransitionCurlDown.

Enough said, the solution is simple. You have to subclass your navigationController’s  popViewControllerAnimated:(BOOL)animated. So create a custom navigationController:


@interface customNavigationController : UINavigationController {}

And a custom “popViewControllerAnimated:(BOOL)animated”, this popViewControllerAnimated-function uses the “UIViewAnimationTransitionCurlDown” when popping from a SettingsTableView.


#import "CustomNavigationController.h"
#import "SettingsTableController.h"

@implementation CustomNavigationController

- (UIViewController *)popViewControllerAnimated:(BOOL)animated
	if([[self.viewControllers lastObject] class] == [SettingsTableController class]){

		[UIView beginAnimations:nil context:NULL];
		[UIView setAnimationDuration: 1.00];
		[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown
					forView:self.view cache:NO];

		UIViewController *viewController = [super popViewControllerAnimated:NO];

		[UIView commitAnimations];

		return viewController;
	} else {
		return [super popViewControllerAnimated:animated];

Use your custom navigationController in your appDelegate:

CustomNavigationController *navigationController =
 [[CustomNavigationController alloc]
