how to hide navigationbar when i push from navigation controller?

Question

how to hide top bar in UIViewcontroller when i push from navigation controller using pushViewController ? any help please?

Answer 1

Put this code in the view controller you want to hide the navigation bar for.

- (void) viewWillAppear:(BOOL)animated {     [super viewWillAppear:animated];     [self.navigationController setNavigationBarHidden:YES animated:animated]; } 

And you may also want to stick this in there, depending on your needs:

- (void) viewWillDisappear:(BOOL)animated {     [super viewWillDisappear:animated];     [self.navigationController setNavigationBarHidden:NO animated:animated]; } 

Answer 2

Here's how to do it in Swift 3:

override func viewWillAppear(_ animated: Bool) {     super.viewWillAppear(animated)     self.navigationController?.setNavigationBarHidden(true, animated: animated) } 

P.S. I found that if you set animated to false, a black bar appears on push. But when it is set to true it's smooth as silk!
