In my program, I have a UIViewController subclass MyViewController and two subclasses of that view controller.
I want them all to use the same xib so I initiate them as
SubClass *SC = [[SubClass alloc] initWithNibName:@"MyViewController" bundle:nil];
[self presentModalViewController:SC animated:NO];
[SC release];
SubClass is a subclass of MyViewController, which is a subclass of UIViewController. In MyViewController.xib, I have File's Owner set to MyViewController.
If I only was going to have two subclasses, I would probably just duplicate the xib but I plan to have many, many subclasses, all using the same xib.

XIB and Storyboard are used for creating interfaces for users. One important point is,xibs are used for creating a single view(it has single file owner at the top of the xib file), but in-case for viewcontroller, multiple screens can be added and its flow can also be monitored(it has separate file owners).
The best way to do this is use cmd ⌘ ,shift, s on the xib or storyboard. Then save it with a new name or location. This is the easiest way to do it, and also the safest, I reckon. Note this is the Duplicate option under the File menu.
You can load any XIB with
- (NSArray *)loadNibNamed:(NSString *)name owner:(id)owner options:(NSDictionary *)options
of the NSBundle class. With
NSArray *arr = [[NSBundle mainBundle] loadNibNamed:@"foo" owner:nil options:nil];
you can load all contents of a XIB into an array. The order of the items in the array is the same you defined in Interface Builder without File's Owner and First Responder.
