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

First way:

Just set .title to ""

Second way:

Just call updateToolBar() whenever you want to show/hide the creeLigueBouton.

func updateToolBar() {
    var barItems: [UIBarButtonItem] = []

    if condition != true {
        // Make it appear
        barItems.append(creeLigueBouton)
    }

    barItems.append(anotherButton)

    myToolBar.setItems(barItems, animated: true)

    myToolBar.setNeedsLayout()
}
