Question

I would be really grateful if someone could explain how to show/ Hide UItoolbar and/or UINavigationBar by single taping. eg like in the fullscreen picture gallery. I would like to implement image gallery with controls on the toolbar which would be dissmissed/revealed by tapping once on the image.

Answer 1

I’d add a UIGestureRecognizer to the view you’re wanting to tap.

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTap)];
   [self.view addGestureRecognizer:tap]; 

- (void)didTap
{
  [self.navigationController setNavigationBarHidden:YES animated:YES];
//Or if you aren't using a nav controller just someToolbar.hidden = YES;

}
