Programmatically call navigation controller back button on iOS
IosObjective CButtonUinavigationcontrollerIos Problem Overview
In a UINavigationController-based iPhone app, in a method I would like to perform the programmatic equivalent of the back button being pressed and going back a view.
i.e. automatically press the Jobs button as seen here:
Is there a generic iOS call I can make, or is more information required?
Ios Solutions
Solution 1 - Ios
UINavigationController's -popViewControllerAnimated: method should do what you want:
[navigationController popViewControllerAnimated:YES];
Solution 2 - Ios
Assuming you don't actually want to PRESS the button programmatically, but simply copy the outcome of pressing the button, you should tell the navigation controller to pop the current view controller.
[self.navigationController popViewControllerAnimated:YES];
This will remove it from the stack, and return you to the previous view controller.
Solution 3 - Ios
Swift 3.0
> Back to the root view
self.navigationController?.popToRootViewController(animated: true)
> Back to the previous view
self.navigationController?.popViewController(animated: true)
Swift 2.3
> Back to the root view
self.navigationController?.popToRootViewControllerAnimated(true)
> Back to the previous view
self.navigationController?.popViewControllerAnimated(true)
Solution 4 - Ios
You should call
popViewControllerAnimated:
which is the opposite of adding view controllers with pushViewController:animated:
Solution 5 - Ios
[self.navigationController popViewControllerAnimates:YES];
is the best option but if you are nor on the same view controller class or your delegate changes before your back button method called then you can also try--
first you have to define back button---
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle: @"anyTitleForBackButton" style: UIBarButtonItemStyleBordered target: nil action: @selector(backButtonTapped)];
[[self navigationItem] setBackBarButtonItem: newBackButton];
[newBackButton release];
and then in backButtonTapped method you can call--
[self.navigationController pushViewController:desiredViewController animated:YES];
