hide and show a ui nav bar button

I am having a situation in which I have to hide the button on the right side of nav bar. Button name is btnRefresh, and I can hide it successfully by this way

self.nvbar.topItem?.rightBarButtonItem = nil

but when I use this for showing it again, it didn't get displayed again

self.nvbar.topItem?.rightBarButtonItem = btnRefresh

Any help???

You need to change the tint color to clear and disable the button as the following : 

let barButtonItem = UIBarButtonItem()
barButtonItem.tintColor = .clear
barButtonItem.isEnabled = false

And to display it again change the color and enable it again : 

barButtonItem.tintColor = .black 
barButtonItem.isEnabled = true
