Usually when I pass in nil as the first parameter of initWithNibName:bundle: it will automatically find the name, but sometimes it doesn’t and it just shows a black screen. Under what circumstances does this happen? There are no errors in the console window and the app happily keeps running as a black screen unless I change the nil to a string literal of the nib name. Where can I check to fix this problem?

    I’ve never passed “nil” in the first parameter of [UIViewController initWithNibName: bundle:] before, but Apple’s documentation says:

    If you specify nil for the nibName parameter and you do not override
    the loadView method, the view controller searches for a nib file using
    other means. See nibName.

    So presumably you’re doing something in your loadView method.

    It’s probably safest (and a best practice) to probably just specify the explicit .xib name when instantiating your view controller.
