How can I dynamically hide a button from a view?

Question

I would like to dynamically hide a button in one of my views depending on a certain condition.

I tried adding some code to the view controller\'s -viewWillAppe

This is a bit of a hack, but it works in my case (and it properly handles dynamic spacing):

To hide:

myButton.width = 0.1;

To show:

myButton.width = 0.0;

A width of 0.0 is "auto width", and with a width of 0.1, the button totally disappears (not even a "sliver" of a button, though I haven't tried this on a retina display).
