Button needs to be disapear and come back - swift

Question

I've got now an app that if you click on a button it will disappear, now I want to make the button disappear even when your not clicking on that button, but it will come back in a few seconds (or even less than a second). On the moment this is how the button looks in the code.
#IBAction func increaseCount(button: UIButton) -> Void {
button.hidden = true
ourScore.text = "\(++score)"
let time = dispatch_time(DISPATCH_TIME_NOW, Int64(Double((arc4random_uniform(1) + 2)) * Double(NSEC_PER_SEC)))
dispatch_after(time, dispatch_get_main_queue()) {
button.hidden = false
}
}
How is it possible to make the button disappear even when your not clicking it, but it will come back in just a few seconds (and less than a second) back? The time should be random between 2 and a half second. When your clicking it should also disappear and it will come back less than 2 seconds.
Who could help me?

Answer 1

This code will have the button appear and reappear on its own every 2 seconds. You can modify the time so it is random (if you need help with that, let me know).
Link your button on the story board and the code below should do the trick.
#IBOutlet weak var button: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
button.hidden = true
NSTimer.scheduledTimerWithTimeInterval(2, target: self, selector: "appear:", userInfo: self, repeats: false)
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func appear(timer: NSTimer) {
self.button.hidden = true
NSTimer.scheduledTimerWithTimeInterval(2, target: self, selector: "disappear:", userInfo: self, repeats: false)
}
func disappear(timer: NSTimer) {
self.button.hidden = false
NSTimer.scheduledTimerWithTimeInterval(2, target: self, selector: "appear:", userInfo: self, repeats: false)
}
EDIT: For the button to disappear when clicked, register an Action event from the button and use the code:
#IBAction func clicked(sender: UIButton) {
self.button.hidden = true
NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: "appear:", userInfo: self, repeats: false)
}
Again, this hides it just for 1 second when it is clicked, but you can change the time to be random.
Edit 2: You should see this:
