Well it makes some sense given that the method that calls it uses those
bits to decide who it should ask to resize (I had assuming you denoted
some axis was resizable). Hard to say how you should solve it without
knowing more about what you are trying to do.

For example you could subclass the containing view and override
resizeSubviewsWithOldSize: among other options.
