NSClassFromString()

No, just use [ClassName class]. NSObject's +class method returns the class itself (in other words, it's as if the metaclass defined -class to return self).

Am I misunderstanding? The given code has an array of NSStrings which are names of controller classes. I assumed Nathaniel wanted to convert one of those names to a class.

NSString *nameOfClass = fooViewController

NSArray *classNameArray = [NSArray arrayWithObjects: @"FooViewController", @"BarViewController", nil];

if ([classNameArray containsObject:nameOfClass])
{
	[[[??????? alloc]initWithNibName:nameOfClass] autorelease]
}

I think the solution is

[[[NSClassFromString(nameOfClass) alloc] initWithNibName:nameOfClass] autorelease];

This may or may not be correct for other reasons, but I *think* it's what Nathaniel wanted.
