Try this :

-(void) changeBarButtonVisibility:(UIBarButtonItem*) barButtonItem visibility:(BOOL) shouldShow {
    UIColor *tintColor = shouldShow == NO ? [UIColor clearColor] : nil;
    [barButtonItem setEnabled:shouldShow];
    [barButtonItem setTintColor:tintColor];
}

and call the above method and pass the bar button you want to hide

[self changeBarButtonVisibility:self.navigationItem.rightBarButtonItems[0] visibility:NO];
[self changeBarButtonVisibility:self.navigationItem.rightBarButtonItems[1] visibility:YES];

Try this

-(UIBarButtonItem *)getLeftBarbuttonItem{

  UIButton *menuButton = [UIButton buttonWithType:UIButtonTypeCustom];
  menuButton.frame = CGRectMake(0, 0, 24, 24);
  [menuButton setImage:[UIImage imageNamed:@"menu-icon.png"] forState:UIControlStateNormal];
  [menuButton addTarget:self.revealController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];

  UIBarButtonItem *leftbarButton = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
  return leftbarButton;

 }

 -(void)showNavBarItem:(BOOL)isShow{

  if(isShow){
      [self.navigationItem setLeftBarButtonItem:[self getLeftBarbuttonItem] animated:true];
  }else{
      [self.navigationItem setLeftBarButtonItem:nil animated:true];
   }

 }

Right BarButton Hide

   -(UIBarButtonItem *)getFirstBarbuttonItem:(BOOL)isHide{

   UIButton *menuButton = [UIButton buttonWithType:UIButtonTypeCustom];
    menuButton.frame = CGRectMake(0, 0, 24, 24);
   [menuButton setImage:[UIImage imageNamed:@"menu-icon.png"] forState:UIControlStateNormal];
   [menuButton addTarget:self.revealController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];
   menuButton.hidden = isHide;
   UIBarButtonItem *leftbarButton = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
return leftbarButton;
  }

 -(UIBarButtonItem *)getSecondBarbuttonItem:(BOOL)isHide{

    UIButton *menuButton = [UIButton buttonWithType:UIButtonTypeCustom];
    menuButton.frame = CGRectMake(0, 0, 24, 24);
    [menuButton setImage:[UIImage imageNamed:@"menu-icon.png"] forState:UIControlStateNormal];
   [menuButton addTarget:self.revealController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];
   menuButton.hidden = isHide;
   UIBarButtonItem *leftbarButton = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
   return leftbarButton;
  }

  self.navigationItem.rightBarButtonItems = @[[self getFirstBarbuttonItem:YES],[self getSecondBarbuttonItem:NO]];

There is no ".hidden" property to a native UIBarButtonItem.

There are a number of possible answers listed in this very related question, and I think the best one for you might be to try subclassing UIBarButtonItem (the HidableBarButtonItem subclass), only replacing the title with an empty string if the item is supposed to be hidden.
