This is a quick tip that will show you how to show hide Navigation Bar when tap in iOS occurs. This is a great method if you want to benefit from every pixel of the screen real estate. So I suggest you do it when you have a view that will display images in fullscreen. An example is when you want to show hide Navigation Bar when the user taps the screen.

A lot of top apps use the show hide Navigation Bar, mainly when opening an image. Twitter, Facebook, eBay and a plethora of famous apps are using this technique. Why not you?

I will show you how in these simple steps in the following code.

Code for show/hide Navigation Bar

UITapGestureRecognizer *tapGesture = 
    [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showHideNavbar:)];
[self.view addGestureRecognizer:tapGesture];
 
-(void) showHideNavbar:(id) sender 
{ 
// write code to show/hide nav bar here 
// check if the Navigation Bar is shown
if (self.navigationController.navigationBar.hidden == NO)
{
   // hide the Navigation Bar
   [self.navigationController setNavigationBarHidden:YES animated:YES];
}
// if Navigation Bar is already hidden
else if (self.navigationController.navigationBar.hidden == YES)
{
   // Show the Navigation Bar
   [self.navigationController setNavigationBarHidden:NO animated:YES];
}
}
