Constant UIBarButtonItem in UINavigationController

Question

Is there any way that I can have a UINavigationController and have it always display the same UIBarButtonItem no matter how many times it is pushed?

Answer 1

Try this-

1. Create subclass(CustomNavigationController) of UINavigationController & use it to push your view controllers.
2. In CustomNavigationController create UIBarButtonItem in init or in viewDidLoad. Add target & action to it.
3. Implement UINavigationControllerDelegate delegates in CustomNavigationController and set barButtonYouCreated as right or left bar button item for each view controller in delegate method.

Use

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
     viewController.navigationItem.leftBarButtonItem = barButtonYouCreated;
}

or

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
