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

Answer 1

This is what I did for button items that weren't part of the navigation bar (where Blank.png is a blank image I created that's the same size of the image it replaces):

theButton.enabled = NO;
theButton.image = [UIImage imageNamed: @"Blank.png"];
