set timer to change an UIButton properties

Question

How can I make a timer that change the properties of a UIButton from hidden to show, and from show to hidden alternating between 4 buttons?

I'm using xCode 4.4

Thanks!

I don't know exactly what to do, but I've tried to use a timer inside a touch down event, but even if this is right, I don't know how to change the properties by codes. — Pablo, Jul 31 '12 at 18:09

 NSTimer *aTimer = [NSTimer scheduledTimerWithTimeInterval: 2.0
                      target: self
                      selector:@selector(onTick:)
                      userInfo: nil repeats:YES];

And, onTick method should look like this

-(void)onTick:(NSTimer *)timer {
   //This is where you need to set your button hidden property.
}

Check this link out.It's well detailed.
