隐藏iOS导航栏？

Question

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?

你不应该在viewDidLoad隐藏Navigation Bar吗？
