Why does UIViewController's subclass's init method sometimes not loading same name nib file?

I know that UIViewController's designated initializer is

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

If you call init,according to the documentation it will load the class's same name nib file(if it exist).

But what I encounterd is that sometimes init does do everything right. But sometimes some UIViewController's subclass 's init method just don't load it's nib file. I create them using the same way(using Xcode's assistant to create a UIViewController subclass and it's associated nib file at the same time, so the file name should all be the same).

Why is this happening?

I figure out that if the class is UITableViewController's subclass, you must use - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil to init from nib.

This is because UIViewController's designate initializer is:

(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

so if you use init,it would therefore call (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil for you.

But UITableViewController's designate initializer is:

- (id)initWithStyle:(UITableViewStyle)style

using initon UITableViewController will call initWithStyle not initWithNibName
