Q:

Hide iOS nav bar?

My program uses 
-(void)viewWillAppear:(BOOL)animated{
        [super viewWillAppear:animated];
        [self.navigationController setNavigationBarHidden:YES];   //it hides
    }
to hide a navigation controller and 
- (void)viewWillAppear:(BOOL)animated{
}
to describe a AVFoundation camera method. I get a warning for using the same method names. Is there another naming convention i can set to use both methods in my app?

A:

Shouldn't you hide the Navigation Bar in viewDidLoad?
