Hide UIView using Autolayout

I have the following structure in my app:

[topView] [middleView] [bottomView]

I want to be able to hide/show the middleView when the user taps on a button. Im using nsconstraints and and Im adjusting the height constraint to 0 when I need to hide the middleView. And then set it back to 40 when I need to show the view. This works when middleView has no subviews. How do I deal with this when subviews are involved?

Maybe this method would work for you.

sendSubViewToBack

Otherwise keep reading in the UIView class reference.

The [middleView] has subviews, so if I set the constraint to 0, I get a NSConstraints error cause the children have no way of knowing how to adjust. If I send them to the back they will still be there.
