I think there may be some error in your logic, below is the corrected code.

#define HELLS_NO !VERY_YES

if ([userName isEqualToString:@"BP"])
{
// by definition !VERY_YES == HELLS_NO
[coolnessSwitch setOn:!VERY_YES];
}

Sure, let’s say you had an application with a preferences dialog, and on the preferences dialog there was a UISwitch (with corresponding IBOutlet) with a label next to it that said “I am cool”, you might have code in your viewDidLoad that looks like this:

if ([userName isEqualToString:@"BP"])
{
[coolnessSwitch setOn:VERY_YES];
}

You’re welcome.

I’m not sure about this, could I see some example usages?
