You'll need to implement -(NSSize)ibMaximumSize in your view's integration class and return the height of your view and an arbitrarily large width (like 100000). Then you'll get the IB behavior you were talking about.
I had tried ibMinimunSize but found that it did not have any effect, so I figured I was at a dead end. It seems in fact that one must implement _both_ ibMinimunSize and ibMaximunSize. Thanks for this hint. So if I do:
- (NSSize)ibMinimumSize
{
   return NSMakeSize (21, 21);
}
- (NSSize)ibMaximumSize
{
   return NSMakeSize (CGFLOAT_MAX, 21);
}
Then IB does indeed stop me from changing the height, but it still lets me make the width less than 21. Why?

I haven't been able to use these methods to get IB to stop a vertical or horizontal resize at a particular point. I don't think IB supports that behavior at the moment.

You'll notice that there are no standard controls that behave in this way. Interface Builder allows the user to resize controls to a non- useful size if the particular axis is resizable (for instance, a slider can be resized to a width of 5 points – not very helpful). There's probably a good reason for this (since the IB plugin architecture is fairly well thought out), but I'm not aware of what that is.
