How to make a button disappear when it is tapped while it is animating

I created a button and set some animations too it but now I can not tap it or interact with it while it is in motion and if it lets me tap it I get an error. My goal is to make the button disappear while it is moving when you click on it. Please help!! Thanks in advance!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    // Create button
    let button   = UIButton.buttonWithType(UIButtonType.System) as UIButton
    button.frame = CGRectMake(100, 100, 100, 100)
    button.setTitle("Test Button", forState: UIControlState.Normal)
    button.addTarget(self, action: "buttonAction", forControlEvents: UIControlEvents.TouchUpInside)

    self.view.addSubview(button)

    UIView.animateWithDuration(4, delay: 3, options: UIViewAnimationOptions.AllowUserInteraction | UIViewAnimationOptions.LayoutSubviews | UIViewAnimationOptions.Autoreverse, animations: {
        button.frame = CGRectMake(100, 300, 100, 100)
        }, completion: nil)

    // Create a function that makes the button dissapear when it is tapped
    func buttonAction() {

        button.alpha = 0
    }

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}
