You'll need to implement -(NSSize)ibMaximumSize in your view's

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.
