Question

I am trying to load a nib file like this:

[[NSBundle mainBundle] loadNibNamed:@"PhotoViewController" owner:self options:nil];

but it makes the app crash

Answer 1

If you’re creating the view controller programmatically, you can use the initWithNibName:bundle: view controller method

I.e.

[[myViewcontroller alloc] initWithNibName:@"myNib" bundle:nil];

If you’re transitioning to the view controller via storyboard, and want to have the storyboard load that view controller from a particular nib file, you could do the following:

1. In the storyboard, delete the view controller’s view
2. Give the nib file the same name as the class of the storyboard view controller
