It is quite late to reply but looking for an answer for my problem I found this topic. The marked answer did not help me, but I managed to solve my problem thanks to @haiLong's answer. My solution works for all types of bar buttons... I think. Add this to your ViewController and use as needed.

var tintColorsOfBarButtons = [UIBarButtonItem: UIColor]()

    func hideUIBarButtonItem(button: UIBarButtonItem) {
        if button.tintColor != UIColor.clear {
            tintColorsOfBarButtons[button] = button.tintColor
            button.tintColor = UIColor.clear
            button.isEnabled = false
        }
    }

    func showUIBarButtonItem(button: UIBarButtonItem) {
        if tintColorsOfBarButtons[button] != nil {
            button.tintColor = tintColorsOfBarButtons[button]
        }
        button.isEnabled = true
    }

I hope it saves some time to other developers :)
