Hide UIBarButtonItem but not make is nil

Is it possible to hide UIBarButtonItem (rightButton of navigationBar) but not making it nil? In my application I have a condition 

if(self.navigationItem.rightBarButtonItem == nil)

which is really important. But hiding the barButton is equally important.

Please check my answer here to similar question. It's applicable here too.

It adds isHidden property to UIBarButtonItem.

You can hide your button by which you have made your barbutton ....

UIButton *button1=[UIButton buttonWithType:UIButtonTypeCustom];
[button1 setFrame:CGRectMake(10.0, 2.0, 45.0, 40.0)];
[button1 addTarget:self action:@selector(showLeft:) forControlEvents:UIControlEventTouchUpInside];
[button1 setImage:[UIImage imageNamed:@"anyImage.png"] forState:UIControlStateNormal];
UIBarButtonItem *button = [[UIBarButtonItem alloc]initWithCustomView:button1];
self.navigationItem.leftBarButtonItem = button;

[button1 setHidden:YES];

One thing you can do is use the initWithCustomView property of UIBarButtonItem. Set up a UIButton and use initWithCustomView and assign it to this button. UIButton has hiding and unhiding property.

UIButton*someButton=[UIButton UIButtonTypeRoundedRect];
UIBarButtonItem*someBarButton=[[UIBarButtonItem alloc] initWithCustomView:someButton];

//To Hide/Unhide
[someButton setHidden:YES/NO];
