func exitApplication() { let app = UIApplication.sharedApplication().delegate as! AppDelegate let window = app.window dispatch_async(dispatch_get_main_queue(), { UIView.animateWithDuration(0.5, animations: { window!.alpha = 0 window?.frame = CGRectMake((window?.bounds.size.width)!/2.0, (window?.bounds.size.height)!/2.0, 0, 0) }) { (finish) in exit(0) } }) }
