objective c - Hide navigation bar

Question

I have 3 views. (say 1st,2nd,3rd). I have pushed the 2nd view (which has a load view method) on the 1st. In the 2nd view I have created the 3rd using initWithFrame (which is inherited from UIWebView). In 2nd view I wrote self.view=3rd view.

Now I want to hide the 2nd view's navigation bar in the 3rd view (i.e., when the user touch to 3rd view screen i.e. UIWebView). I got the touch recognition using gesture, but I can't hide the navigation bar.

3rd view don't support self.navigationController. And if I create 2nd view's object in 3rd, it does not hide the navigation bar. Can anybody help me?

Answer 1

Ok. So you need to set the navigation bar to be hidden right after you create the navigation controller for that tab. You cannot adjust this after you push the view controller (as far as I know).

If you want the first view to not have a navigation bar at the top, then use this in your appDelegate where you initially declare your navigation controllers:

localNavigationController = [[UINavigationController alloc] initWithRootViewController:theViewController];
[localNavigationController setNavigationBarHidden:YES animated:YES];

If you want the views after that to be hidden, then you need a viewController for the subsequent views, and you will have to add

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

right before you call this:

[[self navigationController] pushViewController:theThirdViewController animated:YES];

Hope this helps.
