  • if(self.parentViewController == self.navigationController ) { UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(Done)]; self.navigationItem.rightBarButtonItem = rightButton; self.navigationItem.hidesBackButton = YES; } if(self.parentViewController == self.tabBarController ){ self.navigationItem.rightBarButtonItem = nil; } –  Mar 22 '13 at 11:34
  • The top answer shows setting the button to nil, so it disables it. – petert Mar 22 '13 at 11:35

To Hide the right button: 

 self.navigationItem.rightBarButtonItem = nil;

And 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;

Just write this line in viewDidLoad or viewWillAppear of the class in which you want to hide the right bar button

self.navigationItem.rightBarButtonItem = nil;
