Hide the rightBarButtonItem of a navigation controller

Question

Does anyone know how to hide a rightBarButtonItem of a UINavigationController? In my application, I have an edit button as a rightBarButtonItem

Answer 1

If you need to hide/show the button based on some condition, try this:

if (condition) { 
    self.navigationItem.rightBarButtonItem.title = @"";
    self.navigationItem.rightBarButtonItem.enabled = NO;
} else {
    self.navigationItem.rightBarButtonItem.title = @"my button title";
    self.navigationItem.rightBarButtonItem.enabled = YES;
}

This way you don't have to save a reference to the button in a property or worry about wiring up the action on a new button.
