I believe that you already found a solution for your question, but I'll leave this in case anyone still needs it.

UIBarButtonItem is not a UIControl, however you can initialise it with a custom view, i.e. a custom UIButton programmatically as follows:

let playButton = UIButton(frame: CGRectMake(0, 0, 30, 30))
playButton.addTarget(self, action: "togglePlay:", forControlEvents: .TouchUpInside)
playButton.setImage(UIImage(named: "play-active"), forState: .Normal)
playButton.setImage(UIImage(named: "play-inactive"), forState: .Selected)
let rightButton = UIBarButtonItem(customView: playButton)
self.navigationItem.setRightBarButtonItems([rightButton], animated: true)

idea from Custom "Pressed" UIBarButtonItem Backgrounds
