How do I make and use a Queue in Objective-C?

I want to use a queue data structure in my Objective-C program. In C++ I\'d use the STL queue. What is the equivalent data structure in Objective-C? How do I push/pop ite

re:Wolfcow -- Here is a corrected implementation of Wolfcow's dequeue method

- (id)dequeue {
    if ([self count] == 0) {
        return nil;
    }
    id queueObject = [[[self objectAtIndex:0] retain] autorelease];
    [self removeObjectAtIndex:0];
    return queueObject;
}
