Question

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.

Answer 1

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];
