Title Body

I have subclassed UIViewController into a new class, PageViewController (I'm writing a simple book app). I want to add a new view loaded from a nib file and am using the following code. It works. PageViewController *viewController1 = [[UIViewController alloc] initWithNibName:@"Page1" bundle:nil]; [viewController1.view setUserInteractionEnabled:YES]; [self.view addSubview:viewController1.view]; However, the first line is wrong because I should be calling alloc on PageViewController. When I correct it (below), the code compiles but the xib file doesn't load and the view is just transparent. PageViewController *viewController1 = [[PageViewController alloc] initWithNibName:@"Page1" bundle:nil]; [viewController1.view setUserInteractionEnabled:YES]; [self.view addSubview:viewController1.view]; The PageViewController initWithNibName method has been uncommented and is just the default, setting self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]. What I have tried: In the Page1 nib file, I have tried changing the File Owner class between PageViewController and UIViewController. Yes, I remembered to connect it back to the view outlet afterwards. Help, please! I am stumped.
