RightBarButtonItem disappears when view appears again

My problem is that my RightBarButtonItem, in my navigationItem, disappears after the view appears a second time. The first time the view loads, it displays properly, but the second time it disappears completely.

The button is init'd in viewWillAppear as such:

UIBarButtonItem *optionsButton = [[UIBarButtonItem alloc] initWithCustomView:roundedButton];
self.navigationItem.rightBarButtonItem = optionsButton;

and i remembered to call super

I only touch my navigation controller once more:

Any ideas how this might be happening?

Try this in viewWillAppear:
UIBarButtonItem *optionsButton = [[UIBarButtonItem alloc] initWithCustomView:roundedButton]; self.navigationItem.rightBarButtonItem = optionsButton; self.navigationItem.rightBarButtonItem = nil; self.navigationItem.rightBarButtonItem = optionsButton;

I had the same problem.

If you check the subviews of your navigation-bar, you will see that the barButtons are removed and you have to create new ones.

I tried to store the arrays with buttons before, and add them in viewWillAppear but it did not work so I stayed with create new ones in viewWillAppear.

Implement your BarButton in ViewWillAppear method,so every time when your View Will appear ,you will find the bar button. This will resolve your problem.

- (void)viewWillAppear:(BOOL)animated

{

}

you can use a category to add custom image on navigation bar. Override drawRect method by creating a category on navigation bar. Search on google you will find it. If not let me know. I'll do it for you.

I have always added bar button items in viewDidLoad and never had any problem like yours. Try moving the bar button addition to viewDidLoad.
