/=== VIEW动画====/

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)
