Hide/Show NavigationBar & Toolbar on tap

Question

I'm trying to hide my navigationBar and toolbars on tap, similar to the way the Photos application works.

Any pointers would be greatly appreciated.

Thanks!

Answer 1

这也有效:)

[self.navigationController setNavigationBarHidden:YES animated:YES];

Answer 2

Try to animate the y value of UINavigationBar and UIToolBar like this

[UIView beginAnimations: nil context:NULL];
[UIView setAnimationDuration:0.4];
[UIView setAnimationDelegate: self];
CGRect rect = self.navigationController.navigationBar.frame;
rect.origin.y = -40;
self.navigationController.navigationBar.frame = rect;
[UIView commitAnimations];

Hope this helps you too.

Answer 3

在iOS 8中，您可以通过以下方式实现：

self.navigationController.hidesBarsOnTap = YES

Answer 4

well you can still use the

[self.navigationController setNavigationBarHidden:YES animated:YES];

and you can stop your view from sliding up when the navigation/ toolbar shows. You can have your navigation/tool bar fade in and out over the view without sliding the view. Try this code it did work for me.

self.wantsFullScreenLayout = YES;

that is if you are currently on the view controller.
