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 of a UINavigationController. I want to hide this ? UIBarButton` when some operations are done.

`self.navigationItem.rightBarButtonItems[1] setEnabled:NO];` if you have an array, like if you use flexible space. — Nike Kov, Apr 28 '16 at 12:18

To Hide the right button: self.navigationItem.rightBarButtonItem = nil;

Now, to show it:

If you setup the right button in your view controller by assigning it to self.editButtonItem then simply assign it again in order to show it:

self.navigationItem.rightBarButtonItem = self.editButtonItem;
If you setup the right button in your view controller by allocating and initing a UIBarButtonItem, then simply keep a reference to the UIBarButtonItem in your view controller, and assign it again when you need to show it.

I tried assigning rightBarButtonItem to nil in Objective C it doesn't work for me — Durai Amuthan.H, Nov 25 '16 at 10:24

Try

self.navigationItem.rightBarButtonItem = nil;

When you want it back though you will have to instanciate a button i.e.

UIBarButtonItem *rightBarButton = 
 [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch
                                               target:self
                                               action:@selector(searchBar:)];
self.navigationItem.rightBarButtonItem = rightBarButton;
[rightBarButton release];

what if i dont want to recreate object? for example, i want to hide rightBarButton to wide frame of searchBar on titleView of navigationBar. i mean, does hiding is possible by changing property or something? – Valerii Pavlov Nov 09 '11 at 12:35
if you would like to subclass UINavigationController. you can do: self.topViewController.navigationItem.rightBarButtonItem = rightBarButton; self is your UINavigationController custom class – Jenel Ejercito Myers Nov 23 '16 at 20:06

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.
