Answer 1

If you didn't set the modalPresentationStyle property (like to UIModalPresentationFormSheet), the navigation bar will be displayed always. To ensure, always do

[[self.navigationController topViewController] presentViewController:vieController 
                                                            animated:YES 
                                                          completion:nil];

This will show the navigation bar always.
