Make a UIBarButtonItem disappear using swift IOS

Question

I have an IBOutlet that I have linked to from the storyboard

@IBOutlet var creeLigueBouton: UIBarButtonItem!

and I want to make it disappea

Answer 1

I had the same problem with a tool bar that I had to hide and show its last button. So I declared a var to hold the UIBarButtonItem and removed it from the bar or added depending on the situation like:

inside the class declared the var and linked the toolbar:

var buttonToHide : UIBarButtonItem?

@IBOutlet weak var toolbarOne: UIToolbar!

at the viewDidLoad :

buttonToHide = toolbarOne.items![toolbarOne.items!.count - 1] as? UIBarButtonItem

in my code I made the trick:

if situationOccurrsToHide {
   toolbarOne.items!.removeLast()
}

or

if situationOccursToShow 
{    
   toolbarOne.items!.append(buttonToHide!) 
}

You can use the removeAtIndex or insert(buttonToHide, atIndex: xx) to remove or reinsert the button at a specific position.

You must be careful not to insert or remove the button more than once.

Hope it helps.
