/ ===VIEW ANIMATIONS==== /

class func viewSlideInFromRightToLeft(views: UIView) {
        var transition: CATransition? = nil
        transition = CATransition()
        transition!.duration = 0.5
        transition!.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition!.type = kCATransitionPush
        transition!.subtype = kCATransitionFromRight
        transition!.delegate = self
        views.layer.addAnimation(transition!, forKey: nil)
    }
   class func viewSlideInFromLeftToRight(views: UIView) {
        var transition: CATransition? = nil
        transition = CATransition()
        transition!.duration = 0.5
        transition!.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition!.type = kCATransitionPush
        transition!.subtype = kCATransitionFromLeft
        transition!.delegate = self
        views.layer.addAnimation(transition!, forKey: nil)
    }
   class func viewSlideInFromTopToBottom(views: UIView) {
        var transition: CATransition? = nil
        transition = CATransition()
        transition!.duration = 0.5
        transition!.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition!.type = kCATransitionPush
        transition!.subtype = kCATransitionFromTop
        transition!.delegate = self
        views.layer.addAnimation(transition!, forKey: nil)
    }
   class func viewSlideInFromBottomToTop(views: UIView) {
        var transition: CATransition? = nil
        transition = CATransition()
        transition!.duration = 0.5
        transition!.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition!.type = kCATransitionPush
        transition!.subtype = kCATransitionFromBottom
        transition!.delegate = self
        views.layer.addAnimation(transition!, forKey: nil)
    }



 viewName.hidden=false 
self.viewSlideInFromLeftToRight(viewName)
