Answer 1

What you are actually looking for? In your code you are trying to present a navigationController from another navigation controller.

To present a vieController as a modelViewController you don't need a custom NavigationController.You can present it simply by:

PDFReaderViewController *avController = [[PDFReaderViewController alloc] initWithNibName:nil bundle:nil];
[self.navigationController presentModalViewController:avController animated:YES];
[avController release];
